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.

We had Mike fix our heater. He gave us an honest assessment and fixed our heater. It took some troubleshooting since it was old Heater but he was... good with follow up and explained everything. We are so happy with their honest and kind service. Sometimes it’s hard to find in this market. People are so salesy and trying rip you off. But not this company. I would recommend them to anybody! Will be using them again if need be. (: Thank you for excellent customer service!read more

This is a follow-up to our original 5 Star rating we gave Hamel's for the estimate and negotiation part of the project The unit is now installed and... certified. Installation went quick and smooth. Jack came in with his crew and walked us through the install process. Placement of the indoor air handler was tricky because it was over the stairs to the master bedroom loft. In fact, Jack went out and bought them a new adjustable ladder to make the job safer. Thomas and Jessie did the install and always took time to explain the steps and what they were doing. The outside condenser was set up and tested and by the end of day two was up and running. They ran us through the remote which is has lots of features and left the place cleaner than when they came in. Hamel's office called the next day to see how things went and explained the certification process. They set up a date and time for inspection within a couple of days and then followed up to set up inspection for CA approval. It all went without a hitch. Our only disappointment is the weather changed and we have not needed the new air con at all. Hoping for a heat wave to put our air con to the test. Would highly recommend Hamel's. Their pricing was compatible and their work was excellent. I'd say this was one of out best experiences with contractors we have had. Another 5 STARs for Hamel's.read more

Our air conditioning needed to be replaced in the main dining room of our restaurant during the hottest week of summer. I called Hamel’s and even... though the particular unit we needed was scarce they were able to locate one nearby and had it shipped asap. The day of the install there was a storm moving in and they arrived early in the morning so the crane operator could place the unit on the roof before the winds picked up. They worked through the rain and had us up and running by lunchtime. Luke and his employees are extremely professional and knowledgeable about what the best and most efficient setup for your situation is. I have been using Hamel’s for years and will continue to do so.read more

All members of Hamel who I spoke with and arranged for a new HVAC installation were of the highest professional caliber. Very accommodating,... knowledgeable and with a high work ethic that mandated a commitment to the customer that the installation would be accomplished with the highest of standards. They take pride in the work that they do to achieve customer satisfaction. I felt very fortunate to have Hamel correcting a major problem with such consideration. Luke, Jack, Nick and Amanda are representative of a company that goes the distance. Thank youread more
