"Aire Serv did a great job for me. Tuned up my main AC unit. I expected more charges but everything checked out fine. Thanks! The technician ran short of time, due to the rain. He could only get to one of the units and said they would follow up the next day to reschedule. Unfortunately, they did not follow up and I've not had the second unit completed."

"I would highly recommend First Class for your heating and air needs. My AC went out and they were able to come the same day and fix the problem. Shelby who coordinates scheduling went above and beyond to schedule me that day. She was friendly, courteous and professional. Jonathan Pepper was the tech who came out and repaired my unit. He was knowledgeable, professional and had the best attitude. I could not have asked for better service."

Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.
