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 give this business a million stars. Never have I experienced such great service from such expert installers. They explained, they demonstrated, they checked and rechecked. They made sure that I was familiar with and understood my HVAC system & was aware of how to take good care of it. I highly recommend Nick Hamel and his crew to anyone who is contemplating a new HVAC system.
