"I conducted a lot of research prior to hiring Air Factor, and obtained bids from 6 different contractors. Air Factor was the ONLY company to calculate the size of my home to determine the appropriate size of the AC unit to properly cool my home. They were VERY thorough on the initial visit - spending 2 hours with me. Tim had a great presentation put together, including reviews from customers, insurance information, and BBB ratings/reviews (ZERO complaints by the way). The detailed information he provided built trust in the contractor. I would use them again in a heartbeat, and will definitely recommend them to my friends and family."

"After a sleepless night (too hot) with little AC, I put in a request for AC service with Angi. Within seconds of completing my request, one hour Heating and Air Conditioning reached out. I scheduled service for a few hours later that same day. Cody came out and worked on the system for around two hours to resolve our issue. He stayed long enough to insure the system was working as it should. Upon completion I was expecting a fairly large bill for the service but was delighted to find I could sign up for regular service for a small fee. Everything is working great and we are happy and Cool!"

"Our AC stopped working suddenly due to a grounded compressor. He came out to our house that night, helped diagnose what went wrong (while showing me all the steps he was taking) and was back the next day with a new unit to install. Friendly, punctual, and always kept me updated on everything. Will definitely recommend to family and friends!"

Heating and Air Conditioning questions, answered by experts

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

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.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
