Hamel’s was recently voted San Diego’s Favorite Heating & Air Company in the 2021 & 2022 union-tribune readers poll. We’ve been awarded the best HVAC company of 2022 in the San Diego Reader.

The focus of this list is on the size of the company. While some of these companies may end up on our “Best of Sd HVAC List.” A company’s size does not guarantee quality.

I wanted you to know how much my husband and I were impressed with the three young men who did our installation. They were diligent in their work, courteous, respectful of our property, and honored the time of the appointment. We are so pleased with the work! You are fortunate to have these men as employees. He presented himself well Also, your staff was always courteous and helpful on the phone

Brian and Aaron were GREAT!!! They worked hard installing a difficult floor heater and stayed with it to complete the job late in the day. My thanks for their effort.

I may be an older "woman" but I'm sure as heck not stupid. This was absolutely sales driven!! Guy walks in, gets down on his knees, looks at my floor heater with his flashlight, asks me to look as well. Stands up and tells me it needs to be replaced and it will cost around $5000!!! Says he can go under the house and check to see if there is a "serial number" on the unit. I go outside with him. He bends down,shines the light, says he sees the unit which was over 10' away., stands up and tells me he is going to go out to his truck to see if he can possible find parts for it. The unit is over 65 years old! I call BS!! I WILL NEVER USE YOUR COMPANY AGAIN!! I have had 2 other companies come out and give me a bid of half that price!!Shame on you!!
