"Called Josh on a Saturday morning to report a problem with our heat pump by noon he was here and had identified the problem. We are very happy with this company as they do not use a 1000% markup on parts like some HVAC companies in the area seem to charge. With Air Adviser you get Honest service at an Honest price."

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

Heating and Air Conditioning questions, answered by experts

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
