The Size – Because a residential HVAC system doesn’t need to cool, heat, or ventilate as big of an area, it is smaller than a commercial HVAC system. The components of commercial HVAC systems are different in regard to the blower motor, compressor, condenser fan, damper, evaporator, and thermostat. This is because typically, the size of areas between residential and commercial are dramatically different, a commercial HVAC system has to service larger areas. 

The Placement – Your residential HVAC system has a component placed just outside of your home. A commercial HVAC system is situated on the rooftop or in swamp coolers. Why? 

• A commercial HVAC system is installed on the roof for space-saving. 
• A commercial HVAC system on the roof minimizes noise pollution inside the building.
• Repairs or replacement of commercial HVAC on the roof doesn’t interrupt activities and business proceedings inside the building.   

The Complexity – A residential structure and commercial structure vary in shapes and sizes, so a commercial HVAC system needs to adapt to the structure it is servicing. For a commercial HVAC system, it needs to be adaptable to how the structure is used and the activities inside and may take more electrical power to ease exhaust.

The Drainage – A residential HVAC system is servicing a smaller area, thus has less drainage than a commercial HVAC system. A residential HVAC unit will have one drain pan, whereas a commercial HVAC system has multiple pans and pipes. 

The Mechanism –  A commercial HVAC system is modular and a residential HVAC system is standalone. Because the commercial HVAC system is modular, the parts are installed together for ease of maintenance and upgrade. A residential HVAC system is installed both inside and outside, eliminating the ability to expand or modify the system. 

The Equipment – Commercial HVAC systems are very intensive, requiring them to be customized for effective cooling and heating.  In a residential setting, the variance of the humidity and temperature is minimal compared to a commercial structure and the commercial HVAC system is designed to meet the varying needs of the structure shape and size. Additionally, commercial HVAC filters are different than residential filters and require trained technicians to clean or replace the filters in a commercial HVAC system. 

The Maintenance Cost  – As you can imagine, there is more maintenance for a commercial  HVAC system compared to the residential system. They are more complex, larger, and the mechanism is different. The technicians for a commercial HVAC go through different training than a residential HVAC technician. HVAC technicians can be trained for both residential and commercial HVAC equipment, but most are specialized and focused on one or the other. 

How does a commercial HVAC system work?

HVAC (heating, ventilation, and air conditioning) all work together to create the comfort for the occupants of a commercial structure. For the heating, as the system is engaged, the system’s burners  create combustion gases, and they travel to a heat exchanger. Then the air blows over the heat exchanger, and warm air is dispersed through the ductwork throughout the building.

The ventilation of the commercial HVAC system allows fresh air to enter the building and pulls out any contaminated air. When there isn’t adequate ventilation, the indoor air becomes stale and odors accumulate and linger, allowing a high growth rate of mildew, mold, and other harmful byproducts that are created during the combustion process. 

 The air conditioning part of a commercial HVAC unit utilizes the refrigeration process to cool the air and removes the heat.  This process lowers the air temperature and maintains and appropriate humidity level with an air-cooled or water-cooled system.

What are the different types of commercial HVAC systems?

Commercial HVAC systems come in three main categories with countless ways they can be configured. Which category and why configuration all depend on the individual building requirements and any unique circumstances. The three categories are: 

• A Commercial HVAC Single-Split System: For small commercial properties, this is an affordable and  popular option. It allows individualized cooling and heating per room and large areas. They all work together for a complete environment comfort control. 
• A Commercial HVAC Multi-Split System: The same principles as the single-split system, but the multi-split system can have up to nine indoor units all connected to a single unit located outdoors. Ideal for a larger office space, a healthcare facility, and retail stores. The compressor has variable speeds that rely on inverter technology.  Built-in sensors help conserve energy by detecting small fluctuation in temperatures so that adjustments can be made when needed. 
• A Commercial HVAC VRF or VRV System: A VRF (variable refrigerant flow) or VRV (variable refrigerant volume) system utilizes a heat pump that provides either cooling or heating, a great system for a large open area. Or a Heat recovery system that simultaneously provides cooling and heating, great for a commercial structure with multiple rooms. 

How do you size a commercial HVAC system?

First things first, when determining the size of commercial HVAC system, remember a BTU is the amount of energy required to adjust one pound of water temperature by 1 degree Fahrenheit. Thus, 12,000 BTUs equals one ton. There are four main factors to determine the right commercial HVAC equipment:

• The Application: Grocery store, office space, restaurant, retail, etc.  
• The Building Type: A multi-story structure or a warehouse. 
• The Square Footage: How much space will need to be cooled and heated.  
• The Type of HVAC Equipment: Electric or gas equipment, air cooled, water cooled, etc. 

In addition to those factors, add these into your equation in determining the size of commercial HVAC system too: 

• What are the interior and exterior walls are made of?
• What type of insulation is between the walls, what is the R-Value? 
• What type of flooring is in the structure?
• What type of windows are in place?
• What type of roofing material is on the structure?
• What is the occupancy level of the building?
• What types of electronics, lights, and what kind of lighting is in place?
• Are there plants in the building? 

The actual calculation is an involved process and is labor intensive that has always been done by hand. Today, there are programs designed specifically for the HVAC industry to determine the load calculation. 

Maybe house you move into has an HVAC system already, aren’t they all energy efficient? Absolutely not!  Any HVAC system more than 10 years old is not going to be as energy efficient as an HVAC system today. So, what is HVAC efficiency? 

The energy use of an HVAC system is measured by SEER (Seasonal HVAC Energy Efficiency Rating) which computes the cooling equipment of the HVAC system energy efficiency on an average. An energy efficient HVAC system should get you no less that a SEER rating of 10 to 13 units. There are HVAC units on the market today with a Seer rating of 20 to 28 units. 

What is the most energy efficient HVAC system?

The most energy efficient HVAC system for cooling and heating your home that you can purchase today is a Geothermal heat pump. You want an HVAC system that will keep your home and family comfortable but keep the energy expenses low.  A geo-thermal heat pump can do that for cooling and heating needs. 

A Geothermal heat pump has a EER (Energy Efficiency Rating) between 12 and 45, the higher he number, the more efficient. Little maintenance is required, a plus for homeowners, and have a life expectancy of fifty years. A Geothermal heat pump uses the ground around your home to cool and heat your home, making it one of the most enviro-friendly methods of cooling and heating. 

If a geothermal heat pump pulls heat from the ground to heat your home, how does it cool your home?  The heat pump will remove the heat from the air around your home, transfers it a fluid that circulates into the ground.  The temperature of the ground is 55F, and the heat will dissipate from the fluid to the ground, the results is cold air coming into your home as the result of the heat being removed from the air that is circulating, sending the heat back into the ground. 

Is high efficiency HVAC worth it?

The older your HVAC system is, the less efficient it is, so with a new energy efficient HVAC system, the more you’ll save each month in energy cost and the longer the HVAC system will last.   The other factor in getting an energy efficient HVAC system installed, and this may be as important as the energy savings, is your home’s overall comfort.  

How can I improve my HVAC efficiency?

Yes!  Here, we’re going to offer you six tips on how to make an HVAC system efficient and keep your home comfortable.

• Annual professional maintenance.
  Your HVAC system will be more efficient and perform better with regular professional maintenance. In the spring, schedule an air conditioning tune-up and in the fall, schedule a tune- up for the heating. This will minimize the chance of having any performance problems on the hottest day of summer or the coldest night of the winter, and anywhere in between! 
• Regularly change the filter.
  This is your responsibility as a homeowner! To have the best energy efficient HVAC system possible, change the HVAC filter regularly, a recommendation is every 30 days. This is a simple maintenance task, but the most important to keeping your HVAC system running efficiently and minimize any breakdowns. Every 30 days change the filter, even if it doesn’t look dirty. 
• Install a programmable thermostat.
  A programmable thermostat, can lessen the cooling and heating demands on your HVAC system, and in exchange, you get an energy efficient HVAC system that will save you as much as 15% on your cooling and heating costs. 
• Ductwork inspection.
  You may be surprised what is living in your air duct system. Dander, dust, and more, including critters and insects. These air pollutants in the duct system are pulled through your HVAC system and blow out into your home. Every five years have your air duct inspected by a professional. They will any debris, make repairs if needed so that the air blowing into your home’s air is cleaner and healthier. 
• Energy audit.
  Getting a home energy audit isn’t as scary as an IRS audit, and in fact, it will help you save money by finding where your home is losing energy. A professional home audit will include an evaluation of your HVAC equipment, attic insulation and ventilation, and the doors and windows. 
• Time to Upgrade.
  After the energy audit, you may want to consider getting your HVAC system upgraded with an energy efficient HVAC system. Yes, this will be a costly investment, but it will also improve your energy cost, while it improves the air quality and comfort in your home.     

What is the most efficient heating system for a home?

Just as with the cooling of your home, a Geothermal Heat pump is one of the most energy efficient ways to heat your home too. A geo pump will pull the heat from the ground and circulate it into your home. You’re using a source of heat that is constantly recreating itself and not putting anything into the environment. 

How often should you have your furnace serviced?

Professionally, a gas furnace need to have annual service at the very minimum.  Recommendation is for twice a year, once before winter and again the end of winter. A quarterly maintenance program will follow a heating maintenance checklist designed by the manufacturer of your furnace. This is a good idea when the furnace is 12 to 15 years old. 

The purpose of professional maintenance is for any issues to be discovered before they become a problem and leave you without heat. The benefits of a professional with a heating maintenance checklist are: 

• Prevent Unexpected Costs: Whenever a professional follows their heating maintenance checklist, they often find little issues that can aren’t causing a problem now but will in time.  This is proactive and keeps your home warm in the winter, protects your budget and wallet, and is safer for your home. 
• Energy Efficiency:  When a professional has performed their heating maintenance checklist, they will do the cleaning and oiling that keeps your furnace working efficiently so that it is giving you the best service without costing a fortune each month. 
• Extended Life:  If you have a combined HVAC system, keeping up with the heating maintenance checklist and the air conditioning checklist will assure that your HVAC system will have a long healthy lifespan, giving you years of comfort. 

How often should you clean your central heating system?

The system itself, for your homeowner heating maintenance checklist, as we have mentioned already, should be professional serviced no less than once a year, twice a year is recommended.  As the homeowner, you should change or clean the filter every 30 days and if your home as several animals or live in a dusty area, you may need to do that every 2 weeks. 

For the air ducts, when you start seeing dust collecting as soon as you’ve dusted, it is time to get the air ducts cleaned.  If you don’t have problem with dust accumulating quickly, you should schedule a professional duct leaning every three years. 

How do you service a heating system?

As a homeowner, it is important that you know how do you maintain a central heating system in order for it to work efficiently without costing you a fortune. A professional heating maintenance checklist should include the following: 

• Replace the Air Filter
• Check the Thermostat
• Switch High and Low Wall Returns according to the weather
• Inspect Blower Motor and Wheel
• Lubricate Motor and All Moving Parts 
• Inspect Electrical Wiring
• Inspect Heat Exchanger
• Clean Burners and Check for Drafts
• Check Air Flow and Capacitors
• Check Temperature Difference

Cost savings are always an important issue when it comes to installing an air conditioning system. One distinct advantage ductless systems have over central air conditioning is increased energy efficiency. These units have a SEER rating of 14 or more, and many older central units have a rating of six or less. SEER measures a system’s ability to cool efficiently during a typical cooling season, and the higher the rating, the greater the energy efficiency. What this means for consumers is that ductless systems use less energy to operate, so they will save you money on utility expenses in the long term.

How many ductless units do I need?

Duct air conditioners cool in zones. This means you only cool the rooms that you want to cool. Depending on the size of your home, however, this also means you’ll have to install more than one air handler—the inside unit—in your home, which often means added upfront costs, one of the main disadvantages of this type of system. Most outside condenser units in a ductless system, however, can fit up to eight air handlers. As a rule of thumb, depending on the size of your home, you’ll probably need one air handler per room. Also, the larger the rooms, the larger the air handler needs to be.  

How many square feet can a ductless air conditioner cool?

When you’re installing a ductless air conditioner, the square footage of your property is the key to what size air handler you’ll need to cool each zone. At a minimum, to cool a 150-200 square foot home, you’ll need a 6,000 BTU unit. The larger the space, the larger the unit you’ll need to cool it. For a 400-450 square foot space, for instance, you would need a unit with 10,000 BTU output, while spaces of up to 1,500 square feet require 24,000 BTU.

Can I install ductless AC myself?

Ductless air conditioners require an outside condenser unit and one or more air handlers inside, depending on whether they are single-zone, double-zone, or multizone units. The more air handlers needed, the more complex the installation. While you can install the units themselves with little trouble, professionals are required to install the refrigerant line. The line has to be cut and charged to complete the installation. Some DIY units, however, already have the refrigerant charged and no professional is required for installation.

Does ductless AC add value to home?

While having any cooling system in your home is valuable, many homebuyers view central cooling systems to have the most value because these systems cool the whole home from one centralized unit. However, ductless air conditioners are also highly valued because they are more energy-efficient than central cooling. Either system, though, adds more value to homes than a wall unit does.

Do ductless air conditioners also heat?

Installed on their own, ductless air conditioners are unable to simultaneously serve as heaters. But, if you install a mini-split with a heat pump, then you’ll be able to heat your home. The reversing valve is the key component in this case because it redirects refrigerant flow depending on the season.

Are ductless air conditioners noisy?

Along with being energy efficient, people like ductless air conditioners because they produce almost no noise. The decibel rating is about 25, equivalent to the sound of rustling leaves.

How to clean ductless air conditioner

Like all air conditioners, ductless systems need to be cleaned and maintained regularly so they continue to run efficiently. When cleaning a ductless system, you’ll need to clean both the outdoor and indoor units.

Cleaning the outdoor unit

• Clear twigs, grass, and other debris away from the unit.
• Use a damp cloth and soap and water to clean the outdoor cabinet. Use a dry cloth to dry it.
• Scrub and wash the fan cage or grill by first spraying it with water and using a brush to scrub away excess dirt and grime.
• Use a damp soapy cloth to clean the fan blades, then rinse and dry with a dry cloth.
• Remove dirt from the interior unit with a dry cloth or vacuum.
• Wash off any mold growing on the condensate pan with soap or bleach solution and then rinse it.
• Remove debris or objects that might block water from the drain hose and wash the hose with soap and water.

Cleaning the indoor unit

• Wipe the outside of the air handler with a damp cloth and dry it immediately with a dry cloth.
• Remove the air filters and clean them either with a dry cloth or soap and water.
• Wipe dirt away from the evaporator coils with a dry cloth or use a coil cleaner.

• Energy Efficient, Lower Energy Bills: Keeping your HVAC maintenance up will keep it running at the highest level of efficiency. When it is running at its best, it uses less energy, which means you’re paying for less energy.
• Healthier Air: With proper HVAC maintenance, your home will be cooler in the summer, warmer in the winter, and the air quality will be cleaner, making the air you breathe healthier. 
• Long Lifespan: Routine HVAC maintenance will keep your HVAC unit healthier and give it a longer lifespan. Today, they are given a lifespan of 10 years or more with proper maintenance. 
• Fewer Emergency Repairs: By keeping your HVAC maintenance up-to-date, you’ll have fewer, maybe no, emergency repair bills. 
• Manufacturer Warranty: A manufacturer warranty will be honored when you have proof that you have kept the maintenance up-to-date. After the HVAC system warranty has expired, the practice of HVAC maintenance will also be beneficial for any replacement parts your system may need, and the service warranty will be intact as well. 

What is HVAC maintenance?

As a homeowner, your part of HVAC maintenance is preventive and proactive. You’re doing things like changing the filter every 30 days, cleaning the coils. As long as you create an HVAC maintenance checklist and follow it monthly, bi-annually, and annually, you’ll be doing all you can to keep your HVAC system in good condition. These steps include having the system inspected professionally and tuned up twice a year.

What is included in HVAC tune up?

Most common HVAC inspection and tune-up will include: 

• Condenser Coil Cleaning
• Calibrating the Thermostat
• Checking Refrigerant Levels
• Checking Refrigerant Leaks
• Examine and Tighten Electrical Parts
• Analyze Blower Belt and Motor Operation 

How long does HVAC maintenance take?

A professional HVAC maintenance process takes approximately two hours maximum, depending on the HVAC unit. It isn’t an all-day thing, but it is worth your time as part of the investment to your HVAC system and your home. 

How often should you have HVAC maintenance?

The HVAC system in your home should be checked and inspected no less than once a year, twice a year is recommended with one the spring before the summer heat and again in the fall before winter cold. If your HVAC system is a heat pump, definitely twice a year is needed. 

When it comes down to it, as a homeowner, comparing the hassles of HVAC maintenance vs HVAC repair cost, the time to perform HVAC maintenance is well worth the savings. This simple checklist of preventive maintenance is doable and manageable. Doing the preventive maintenance steps that we’ve discussed should not be a replacement for hiring a professional HVAC company no less than once a year to inspect and perform professional maintenance on the HVAC system each fall and spring. They will inspect all the mechanisms and wiring for both parts of the HVAC system air conditioner and furnace. Dial (678) 964-5617 today for your HVAC maintenance in Lawrenceville, GA.

1. Hot Air: If your air conditioner system is only blowing sultry air, it could be the compressor has quit working or there is a refrigerant leak. Both can be sometimes be repaired, and the repair is much less expensive than replacing the entire HVAC system. The emergency ac repair technician will conduct tests on the compressor and other parts, check for refrigerant leaks, and advise you what they have diagnosed to be the issue. 
2. Moisture: If you have noticed moisture or water around your air conditioning system, that is a sign that something is wrong, but it may be a minor issue, like the drain tube is blocked and the condensation is backing up. This does not makes an emergency ac repair, but it constitutes getting tended to immediately before it becomes an emergency ac repair. Check the drain and drain tube, clear any obstruction away and clean up the water. If the drain is working and the moisture appears again, it is possible you have a refrigerant leak, and that is an emergency ac repair. 
3. Sounds: An air conditioner that is running correctly should run quietly. A quiet, steady noise coming from the motor is a normal sound. The sounds that aren’t normal is a grating, grinding, or squealing sound. When you hear any of those noises, you need to make that emergency ac repair service call immediately after you have turned the system off. These sounds mean something isn’t working properly and leaving the system on could burn up the motor or other components inside your air conditioning system. 
4. Smells: A strong and powerful smell could be the insulation in and around the air conditioning system is burning. It can also be from mildew and mold. Either way, you need a professional service to inspect your system and make any repairs needed. If the smell is a burning smell, turn the system off and make an emergency ac repair call. If the smell is mildew or mold, clean what you can around and inside the general area, like the drain, and replace the filter. If that doesn’t clear the odor, then call for a basic service call to have your system professionally inspected and cleaned.  
5. Humidity: Your air conditioner pulls the humidity from inside your home if it is proper working order. If you notice water pooled around windows or the air in your home is sticky feeling, this is a sign that your air conditioning system isn’t working right. It isn’t a need for an emergency ac repair call, and you can change the filter, that may help.  Otherwise, you need to get a professional scheduled to check your system out and make sure all is in working condition.   

Is air conditioning not working an emergency?

If your air conditioner isn’t keeping you cool enough, is that what is an ac emergency is? Failure of an air conditioning system is NOT always considered an emergency – in general. However, we all have a different level of discomfort with heat, so if it is miserable hot to you and your air conditioning system isn’t cooling your house fast enough for you, it is your opinion and your bank account if you want to make that emergency ac repair call. Remember, after hours and off-days are charged a higher rate by HVAC service people. 

What is considered an air conditioning emergency?

The following situations constitutes as an emergency ac repair and you should contact your air conditioning service company immediately: 

• Strange Noises: A loud screeching sound could be a loose belt or the compressor freezing up. Turn the unit off and make that emergency ac repair service call.  Do not turn the system back on until the technician has a arrived, inspected, repaired, and gives you the all-clear sign. 
• Air Flow: If there isn’t any air flow coming from your air conditioning unit, this could be sign that your system has a major failure and you need to make that emergency ac repair service call.  This is something that a trained professional needs to inspect and diagnosis. 
• Unusual Odors: If you smell something burning coming from your air conditioner system, it could likely be something with the electrical components within the system. Turn it off immediately and the make that emergency ac repair service request. 

Here is a list of the most common types of emergency ac repairs that technicians all around the country experience with emergency ac repair requests:

1. Unusual Noises and Sounds
2. Warm Air Blowing from Vents
3. System Repeatedly Cycling Fast
4. Ice Inside or Outside the System
5. Humid Inside House with Air Conditioner Running
6. Unpleasant Odors
7. Air Current is Weak
8. Breakers Keep Tripping
9. The Fan Not Blowing
10. Thermostat Not Working
11. Air Conditioner Not Blowing Cool

So, how long should an air conditioner last? A well-maintained air conditioning system can last 20 years, maybe longer. By well maintained, this means regularly changing or cleaning of the air filter and keeping debris away from the exterior unit. It also means having a professional inspection of your unit twice year to make sure everything is in proper working order.  That service call can save you a lot of money by not having to make that emergency ac repair service call. Dial (678) 964-5617 today for your ac needs.

What are examples of energy efficiency?

We can consume less power to reduce the toxic fumes from the power plants by switching to other power sources like LED light bulbs and solar power. By going solar with as much as possible, we are conserving our natural resources and protecting the ecosystem. We can do our laundry in cold water and hang them to dry instead of using hot or warm water and not using a clothes dryer. We can all practice energy efficiency with examples like these: 

• Repurpose: Since we’ve already used energy and resources to make things, let’s use those things! Repurpose an old building using recycled materials and products. 
• Passive Designing: Design structures with more windows so less electricity is needed. Build cool buildings in the south and warm buildings in the north.   
• Use Free Resources:  Solar energy is free. Using solar panels is capturing that free energy instead of using generated electricity, a great energy efficiency way to live. 
• Design with Efficiency: Design and build things with engineering that will use less energy. One example is the incandescent light bulb versus the LED light bulb with 5% energy efficiency versus 20% energy efficiency. 
• Our Way of Living: Making small changes to our lifestyle can make huge impact on energy efficiency like living closer to work and changing dress codes in the office for summertime. 
• Powering Down: A huge source of energy efficiency is to turn off anything you’re not using, like extra lighting indoor and outdoor, televisions, fans, computers, etc. 
• Maintenance and Upkeep: By doing the maintenance and upkeep around our homes, this keeps things like the air conditioner and appliances running property is a great source of energy efficiency. 
• Reduce Waste: Fixing water drips and leaks, adding insulation to the attic, and other energy saving measures is one of the best ways a home can have more energy efficiency. 

How can we increase energy efficiency?

You may feel like you’re practicing energy efficiency all you can at home, there may be a few more things you can do. The following things may cost you money upfront, but in the long run, the money you’ll save will be a bonus.

1. Upgrade Appliances and More: If your home has appliances, air conditioning, or heating that is more than fifteen years old, you will save a lot money over time with new components that are designed for energy efficiency.  Other home improvements that will help your home with energy efficiency and sustainability is new doors and windows and adding insulation to the attic and improving the ductwork can do wonders for both.
2. Programmable Thermostat: Purchase a programmable thermostat will enhance the cooling and heating efficiency by being able to set the climate control to achieve optimal temperature at a minimal cost. Once you have the temperature settings to fit your home’s occupancy, it isn’t just a matter of energy efficiency and comfort, but easier too. 
3. Add Caulking and Reseal Doors and Windows: Not everyone can afford new doors and windows but caulking and weather stripping can improve energy efficiency at a fraction of the cost and still make a difference in the utility bills. 
4. Add Ceiling Fans: Ceiling fans made a splash in the 1970s and then as home decorating shows took to the airways, they were coming down fast. Now, homeowners are realizing that they created a gentle breeze and circulate the air too. During the summer, they keep the hot air up and during the winter, they keep the warm air down. Both are energy efficiency that save you money on utilities.   
5. Water Energy Efficiency: Install low-flow faucets, showerheads, and toilets that use the minimum water needed to accomplish the job needed. These are fairly easy to install and within just a few months, you will notice the savings on your water bill. Next time your water heater needs replacing, go with the new tankless style that produces hot water on demand, using less energy than the traditional water heater. 
6. Light Improvements: Each time you have to replace a lightbulb around the house, use a CFL or LED bulb instead of the traditional light bulbs will be energy efficiency and money saving too.  Replace a light fixture each month and you’ll notice a savings on your electric bill, and if you can’t afford new lights, go natural as much as you can using the light from the windows. 

Be smarter with your laundry days by doing only full loads and cold water. Be sure tore change or clean your air conditioner or HVAC filters every 30 days, and where possible, find other ways to cool and heat your room. Dial (678) 964-5617 today for your energy efficient AC needs.

Some of these things can cause the cooling lines to freeze up with air conditioner refrigerant. Once you have checked each of these troubleshooting tips, you’re still not getting frosty air from your air conditioner, you must call an authorized, experienced repair service.

The sooner the better, and not because it’s getting hot and they’re getting busy, but because the longer you wait, the problem could get worse. How? If there is any water leaking from the system into the attic walls or under your house, the problem will grow into a bigger problem.  

How do I find a leak in my AC?

Budgets are tight for everyone, so it is understandable that you want to do as much as you can yourself when it comes to home repairs, like your HVAC system. Fortunately, technology has come to the public so that you can purchase some equipment, supplies, and tools, like air conditioner refrigerant, that once were only available to authorized, experienced, and licensed technicians. 

However, if you don’t know how to correctly us them, you could do more harm than good. As we provide you the following steps for checking the air conditioner refrigerant to your HVAC system, make sure you read the instructions and follow the directions. You may ask yourself, “Is air conditioner refrigerant harmful?” and we have to give you an astounding YES!  It must be handled with care and used properly. If this gives you any doubt, call a reputable air conditioning repair company. Err to the side of safety, not budget. 

Dealing with AC refrigerant leaks and air conditioner refrigerant charge can be stressful. Before you explore the possibility of doing this yourself, ask yourself if you can afford a new HVAC system. Because if you do this wrong, that is exactly what you could need next: A new HVAC system.

How do you know if your AC needs refrigerant?

These four things are signs that you may needair conditioner refrigerant added to your HVAC system:

1. The energy bill increased, but your house isn’t feeling any cooler. This typically means your AC must work harder to keep up with the demands of the thermostat.
2. The vents have warm air coming out instead of chilly air.
3. You see frost or ice on the coils in the outside component of your AC system.
4. You’re hearing bubbling or hissing noises coming from the internal component.

With summer here, for most of the country, we’ll be turning on that air conditioner. If run your AC without refrigerant, you will not get cooled off at all. In fact, you will get heated up in frustration.  Call your local HVAC technician today and get your system ready for those hot summer days and nights. For your air conditioner refrigerant recharge in Lawrenceville, GA, call (678) 964-5617 today.

Which is better ductless AC or central AC?

A ductless air conditioner is less noisy than central AC systems and since condensers are smaller they can be located away from the home to minimize noise. Ducts will also echo noise which can amplify the sounds of moving air. Since a ductless air conditioner uses hoses the echo is not there so the system will be quieter. What’s more, a ductless air conditioner will be more energy-efficient as it is designed to be operational per square feet of space.

How long do ductless air conditioners last?

A ductless air conditioner if well maintained can last up to 20 years. This is longer than most AC options which tend to last anywhere from 10-15 years.

Are ductless AC units more efficient?

A ductless air conditioner will be more efficient with energy use as it cools homes faster. They have fans that can change their speed based on the conditions outdoors and indoors. These variable speed air handlers are in most ductless air conditioner systems.

Are ductless air conditioners noisy?

Ductless air conditioners are one of the quietest ACs on the market with an average noise level of 32 decibels. A ductless air conditioner also has some of the highest SEER ratings and one of the highest efficiency performances as well.

Where to Place Ductless Air Conditioner

A ductless air conditioner is usually mounted on the wall indoors at least 10 feet from the floor, this will avoid sending air to the ceiling. Units can also be installed in the bedroom and should be placed directly above the bed or above your feet on the wall for better comfort.

How long does it take to install a ductless mini split?

A ductless air conditioner can be installed with skilled professionals pretty quickly and without complications. The average installation usually takes 1-2 days for completion yet the length of time will depend on the size of the system and how many indoor air units need to be mounted in the property.

How much does it cost to install a ductless air conditioning system?

Why is my heater not working in my house?

• A dirty air filter
• Leaky ductwork
• Problem with the pilot light if it’s a gas furnace
• A broken or malfunctioning thermostat
• The blower is malfunctioning 
• A faulty heating element causing the heater to blow cold air

These are just some problems that will require central heating repair. Again, it’s best to consult with an HVAC professional to ensure the problem is diagnosed and repaired properly.

How do I fix my central heating system?

If your heater has stopped working properly you want to get a professional out for major central heating repair. There are some actions you can take, however, before calling out the technicians to troubleshoot the system. The thermostat is the first place to check when there is a problem with your HVAC, especially if you have a battery-operated thermostat. Test the batteries and change them if they are low. Follow up by switching the heat on the thermostat, and if the heat doesn’t come on, check your circuit breaker to see if a circuit has been tripped. You can also check the furnace door. If it isn’t fully closed, a switch inside the door will shut off power to the furnace as a safety measure. 

Next, check your filter. If it is dirty, it needs to be changed. A dirty filter can stifle airflow in the system and even cause the system to shut down. If you have a gas system, check the pilot light or igniter. You can try to reset the igniter by first shutting off the gas reset valve in the unit, wait five minutes and turn it back on. If you have gas and this doesn’t reset the igniter you will need to replace the igniter. You may also want to check your registers. If any are closed, they can affect airflow.
