It can be overwhelming looking for the biggest or The Best HVAC & Furnace Company in San Diego, California. We at Hamel’s hear this from potential clients every day. But, with Google searches and word-of-mouth recommendations, it’s hard to know who to trust.

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. While we’re confident in our award-winning service and being customer-focused, we also understand knowing your options is essential. For this reason, we have compiled a complete list of who we consider the biggest HVAC companies in San Diego.

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. Maintaining a large number of highly skilled workers can oftentimes be extremely difficult. In turn, that may affect the quality of service received.

I have a home that is >100 yrs old with floor furnaces that most companies will NOT touch. I was relieved to find that Hamel's is not daunted by older homes.Aaron called ahead and was able to arrive early which was excellent for my schedule. He quickly diagnosed the problem, remedied it and was on his way in less than an hour.They are now my go to company for floor furnace issues.

We just had Hamels(Greg, Corey, and Aaron was our team) replace our entire HVAC system. We couldn’t be happier with the results, the quality of the system recommended, and the work performed. They found code issues in the attic with our old system and willingly corrected those issues to code. Particularly noteworthy was the care they took protecting the interior of our house, my wife and I really appreciated that. We wanted to have a local company do the work and we’re so happy we did. If you need any heating or air conditioning work, we can recommend Hamels without reservation.

The whole system and process was great. The technicians were all knowledgeable, professional, very courteous. I feel I received a great value. My brother who runs his own plumbing company recommend Hamel's and I liked their proposal the best compared to the other two companies.
