The 6 Biggest HVAC Companies in San Diego

How to find the best HVAC Companies Near me

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 discuss this concept extensively in the following article. Learn how to find the best local HVAC company near you.

I was very impressed with Luke Hamel's knowledge and professionalism, plus that he listened and answered all my questions and concerns without... hesitation, as we went over my existing heating and air conditioning system.When Bradley, Hamel's estimator/proposal representive, came to my home a couple of days later, he examined every nook and cranny available to see where the system would/could be improved. The company's digital camera pictures showing the attic, along with highlighting the ducting, was great. This also allowed Bradley the option of having the exact square footage for all the rooms in my home.After checking and asking many questions (plus getting input from many people with good intentions), I feel completely confident in using Hamel's Air Conditioning & Heating.Hamel's owner, Luke, and Bradley provided a feeling of confidence in what will be "a job well done".Kay Larimerread more

Luke Hammel himself came to troubleshoot my HVAC unit and found the discrepancies in a timely fashion. Corrections were made and it was surprisingly... less than I anticipated.read more
