Kevin Gaines is awesome. He’s friendly and so competent. He answered many questions I asked about the furnace. I had questions about the water heater as well and he went the extra mile to send pictures & get answers from the proper person. I will definitely sign up for their furnace checkups and will ask for Kevin for the visits. I’m sold in the company thanks to Kevin!

My hvac company told me I needed a new compressor after it stopped warming my home as much as it used to. I called Kevin Gaines of National Heating and Air. After diagnostics and visual inspection, I discovered unattached wires and an incompatible capacitor were the reasons for my problems. After these issues were corrected, my house heated up quickly, just as it used to. I was happy to feel the heat again and relieved I did not have to worry about the expense or inconvenience of replacing my compressor. Thank you much, Kevin.

We couldn’t be more pleased with Kevin’s services this week. He assessed the problem for us on Sunday and had our heat pump back up on Wednesday. Kept the temperature needed in the furnace mode in between. We’re in Florida most of the year, so we’re totally dependent on his skills. Our thanks to Kevin for a great job.
