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.

Had my scheduled spring tune up on Monday to turn the AC on and test it before summer hits. Unfortunately a problem was found, tech worked well and... found the isssue was a contactor. I was at work so he called me to explain and he said with our membership this service call would be covered for free and wouldn’t count as the spring tune up. He could fix it on the spot but I wasn’t ready to spend the $540 for a contactor. He agreed there was no rush since we have some time before hot weather.When I got home I looked at it and noticed he had unplugged one wire from the contactor and taped the butt connector up. Don’t understand why this would be needed if the AC disconnect switch was pulled and no power was going to the AC unit. Maybe this is common practice? Or was part of the diagnostic, just seems like a high estimate for an easily accessible $20 more
