"Air Serv was the finest contractor that we have ever used. No stress, no worries about the service personnel or the Technicians. Very courteous personnel at all levels of the Company. Any questions we had were answered thoroughly and efficiently by Ken Q, our representative. On these hot and miserable humid days we (my family) send a whole heartly "Thank You" to Air Serv for everything that have done!!"

"This was for semiannual maintenance under contract. Danny performed an excellent job, he has many years of experience. I have used ARS for the heating/air conditioning maintenance for about 35 years. They replaced the equipment about six years ago. It has not failed since replacement."

"My Mother is 91 years old and her air conditioner went out. One of your technicians, JOE BIGO came and gave my Mother a estimate on a new unit. Joe was very polite and very professional. Joe went out of his way to work with us so my mother can get another air conditioner unit. You all are coming next Thursday (20th) to install her unit. Excel is the only ones that my husband and I have service our air and heating in our home. We are always very satisfied with yals service. Thank you Joe for coming out and working with us for my Mother. She is excited about getting her new unit.My Mother also thanks you Joe.We really appreciate every thing you did. You made her day. THANK YOU SO MUCH JOE."

Air Conditioning questions, answered by experts

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours.
