San Diego Commercial HVAC Contractor

Additionally, we are backed by York®, a multi-billion dollar company based on technical innovation and business relations in the market place.

California Design Build & Installation

Every business is different. Even the same business in different locations has varied needs. We know that a department store differs greatly from a grocery store in its HVAC requirements. Even if you try to establish a high degree of standardization throughout your buildings, you need a California contractor who can help combine standardization with a sound understanding of different applications. Each of our jobs is different, yet each builds on the expertise we have acquired over our years of service.

Properly designed systems achieve higher performance levels and efficient operation. Conversely, a poorly designed system will affect load capabilities and running costs. You can rely on our commercial design build services to calculate things like part-load efficiency, unit placement and system flexibility, providing you with ideal recommendations for your specific requirements. We execute commercial HVAC installations according to code resulting in a reliable, high performance solution.

A commercial heating, cooling and ventilation system is no different than any other equipment: it requires attention to maintain peak running efficiency and performance levels. 5 Diamond Heating and Cooling preventive maintenance plans cover everything from tune-ups to seasonal preps and routine filter changes. Avoid the downtime and costly repairs associated with a neglected system by entrusting us with the ongoing care of your investment!

 

These guys are life savers! Over the holidays, I'd installed a Nest thermostat. I did it myself, meticulously following directions. But it wasn't heating like it should. I called one of the big-name HVAC services (you probably know their TV jingle), but they didn't work on Nest equipment. So I got 5 Diamond's number from the list of service pros on the Nest website. Carlos answered on the first ring and said they could fit me in today! Nick showed up right on time and couldn't have been nicer or more helpful. He explained my system to me, so I would understand what he was doing and why. It took some detective work to figure out the issue, including getting up on the roof, but he fixed it. And the charge was very reasonable. This is a small outfit with no fancy TV jingles--just prompt, competent, reasonably priced service. I will definitely use them again!
