Frequently Asked Questions

Please take a few minutes to read through our frequently asked questions and answers to find helpful information about our company, our products, and our services.

Can I install my own air conditioner?
Installation requires a license and a highly trained installation crew to ensure the unit is installed correctly and to check for any potential issues that only an experienced technician knows to look for.
Do air conditioning units need servicing?
Yes, all air conditioning units need servicing. We recommend all units to be serviced twice a year to ensure any possible issues are found early. For this reason, we have tiered maintenance plans.
How can I keep my room cool without AC?
The best way to keep cool without ac is by keeping shades closed and running a fan. A fan does not make the room cooler but it does make you feel cooler in a room.
How do I reset my air conditioning unit?
Air conditioning systems don't have a reset button. If there are issues, you should have the unit inspected by a professional and if any issues are found, they must be repaired.
How do you install a central air conditioner?
Installation is a difficult process that involves locating and creating all of the ductwork required to move the air through the house. It is a process that should be left to a trained and skilled professional.
How much does it cost for AC maintenance?

What are some signs that my air conditioning system may need repairs?
Some of the biggest signs that your air conditioning needs repair are:
  • No longer blowing cold air.
  • High humidity in parts of the home.
  • Unable to keep the home at the set temperature.
  • Water leaking from the unit either inside or outside.

Who is the largest air conditioning manufacturer?
The largest manufacturer of air conditioners is the Carrier / Bryant brand.
Why do air conditioners stop working?
Most air conditioners stop working due to failed parts. After 10 years of regular use, many parts begin to wear out. There are many common parts that wear out first which is what our technicians will check for during regular maintenance.
How much does emergency AC repair cost?
The cost of emergency AC repair varies by the severity of the repair. Typically, between the service call, parts, and labor a minimum cost of $250 can be expected while in some severe cases a repair can cost over $1,000.
Why does my hot surface igniter keep breaking?
Repeat hot surface igniter failure can be caused by a few things. One is improper handling of the igniter during installation. The surface of the igniter should not be touched. Oils from the skin can cause premature failure. Also, a failing igniter should be upgraded to a silicone nitride igniter. This type of igniter is slightly more expensive, but typically outlast the life of the appliance.
How long does it take to repair an air conditioner?
A repair can be made in as quick as 15 minutes or take as long as 3 hours.
Should my AC unit run all day?
You should hear your a/c unit cycling on and off regularly. If you hear the system running non stop and you do not have your fan programmed to run continuously, you should check your filters. If they are clean, call for service.

Do heating and air conditioning systems really need regular maintenance?
The simple answer is yes. Regular maintenance services and tune-ups can extend the lifespan of your system, increase its working efficiency, and allow technicians the opportunity to catch and address minor issues before they become major problems. This ultimately saves you money in the long-run, not to mention time and stress.

At ABA Heating and Cooling, we recommend that you schedule tune-up services twice a year - once before the start of the summer months and once before winter begins. This can help you avoid unnecessary problems during the hottest and coldest months of the year.

If you have disposable filters, we recommend that you replace them at least once a month. If you have washable we recommend they be cleaned once a month. For media filters they only need to be replaced once every 3 months.
What size air conditioning and heating system should I have?
Selecting the right size heating, ventilation, or air conditioning system is important as it can improve your home's energy efficiency, reduce costs for homeowners, and ensure that your home stays comfortable all year-round. There is no one-size-fits-all rule for choosing the right size air conditioning and heating system; instead, a trained technician can look at various factors, including the size and construction of your home, and use this information to determine what size air conditioning and heating system you should have. At ABA Heating and Cooling, we provide free in-home energy analysis services to help you select the right system for your unique needs.
What are the benefits of a wifi/programmable thermostat?
Wifi and programmable thermostats have many benefits the biggest being that they help conserve energy which in turn helps lower your electric bill. Programmable thermostats can also allow you the ability to automatically set the ideal temperature for different seasons or times of the day, wifi thermostats also have this capability however, because its connected to the internet you have the convenience of being able to adjust it from you cell phone.
How important is indoor air quality?
Most homeowners don't think about the indoor air quality of their home, but it is actually very important to the overall comfort and health of you and your family members. When it comes to indoor air quality, it's important to keep in mind the following factors: ventilation, purification, humidity, and filtration. Our Comfort Specialists can help you assess your home's indoor air quality and select the right purification or filtration system, or humidifier/dehumidifier for your home.
How can I increase my home's heating and air conditioning efficiency?
The best way to increase the energy efficiency of your home is to select an efficient air conditioning and heating system. When it comes to heating and air conditioning, bigger doesn't always mean better. In fact, larger systems with more capacity can actually lead to reduced efficiency as they tend to cycle more rapidly, turning on and off frequently while in use. Choosing the right size air conditioning and heating system for your home can improve its overall efficiency and cleaning and replacing filters frequently can also lead to improved functioning of your system. Keeping the blower in the "on" position can also help your system heat and cool your home more efficiently as this allows for better filtration and constant air movement throughout your home. Finally, installing a wifi or programmable thermostat can also increase energy efficiency because you can program the temperature settings by the time of day.
How can I tell if I need professional air conditioning and heating service?
Generally speaking, if your heating, air conditioning, or ventilation systems are not working properly, it's wise to schedule service with a trained professional. How can you tell if your air conditioning and heating system isn't working properly? Check for strange noises, unusual smells, reduced efficiency, higher energy bills, or other unexplained issues with your home's systems.
When should I replace my air conditioning or heating system?
Many factors play a part in determining if you should have your A/C or heating system replaced, including how often it is used, the system's overall efficiency, whether or not the system is meeting your personal comfort needs, and if repairs would be more costly than a full system replacement. Lifespans for A/C and heating systems vary but, generally speaking, most air conditioners last 12 years, as do most furnaces.
What is the SEER Rating?
The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 21.
How can I keep my air conditioning drain line clean?
Pouring a cup of bleach in the access opening in the drain line near the AC unit will help to kill any algae, mold, or mildew that has formed in the pipe. If the condensation line is clogged, you will most likely need to call a trained professional.
How does the phaseout of R-22 (Freon) affect me?
R-22 is a refrigerant often used in air conditioners and heat pumps. Because R-22 depletes the ozone layer, production and import was significantly reduced in 2010. Since 2015, there has been almost a complete ban on the production of R-22. The price of R-22 refrigerant is skyrocketing as we speak. It has already doubled since this time last year and is expected to triple in the next few years, and the supply of R-22 refrigerant is already limited, and as the phase out continues and prices rise, you can expect availability to fall. If you have an existing R-22 heat pump or air conditioning system, you do not have to rush out and buy a new R-410A system right away. You can continue using it, but at the very least, you should make sure to properly maintain your unit. Regular servicing minimizes potential environmental damage along with the higher maintenance costs due to mechanical breakdowns or refrigerant leaks. But for our customers who have R-22 systems over 10 years old, you may want to consider replacing now rather than later.
Should the thermostat be set at ON or AUTO?
Variable speed equipment utilizes the fan ON mode very well. This method constantly circulates the air keeping temperatures even and takes advantage of air purifying equipment.
What maintenance can I do myself?
Keeping filters clean in furnaces and keeping foliage away from condensers at least 12 feet are the best things you can do to keep your equipment running smoothly on your own. Call ABA Heating and Cooling for annual tune ups and safety inspections to ensure your equipment has a longer life. We will perform maintenance and troubleshoot other problems too.
