Highly recommend Bell for all your HVAC needs

I called Bell a/c to just do a checkup for my a/c before the heat starts. I was so impressed with the young man Stephen.
“He came in wearing a mask, booties and told me what to expect. He was so polite, knowledgeable, explained everything he was doing. I expected him to say that I needed a new unit (it is about 20 yrs. old) but he said it is working very well- needed nothing - not even Freon. Last year I used a different company and was told that I would need to replace the entire unit within a yr. which I didn't. I appreciated his honesty.”Leslie -
Fantastic Sales Rep - Giovanni
“I contacted Bell for estimates to install 3 hvac/places. I heard back from another contractor that I had contacted before Bell, so the timing was not right for me to choose Bell. However, I wanted to say that Giovanni was so helpful, had a wonderful manner and represents the company so well that I would contact Bell for any future needs. This was the first time in a long time that I had a conversation with a company representative that truly puts the customer's needs first. Kudos to Bell!”LBL
