"Justin and his assistant did incredibly high quality precision work removing an old furnace and installing a new furnace and AC. The price was very competitive and work was scheduled and completed quickly. It was amazing to see such high quality work after working with so many mediocre companies."

"Air Pros did the heating & A/C in our home when we remodeled last spring. Sheldon and I discussed my project and after going over the all the options we chose to go with splits for heating & A/C. Sheldon and his crew were very professional, they showed up as scheduled, were very efficient and always left the site clean. I was very impressed with there work and pricing. Ii was so pleased with their work that later last year I had them replace heaters at two other properties. This work involved installing new gas heaters and modifying some duct work. Again we were very pleased with Air Pros work. They worked out a schedule with the occupants and we’re in and out in one day at each site. Thanks Air Pros get a 5 stars rating from us."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Air Conditioning FAQs, answered by experts

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

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.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
