San Diego Commercial HVAC Contractor

Your business relies on an economical and robust solution that will provide reliable performance and high operating efficiency. We understand the demands of commercial HVAC applications, and have the technical experience required to provide you with superior design build and installation services. 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.

Preventive Maintenance

5 Diamond Heating and Cooling provides our San Diego customers with extensive preventive maintenance plans. 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!


It all started with a Groupon to check why our furnace wasn't blowing hot air and to perform a tune up on our lagging AC unit. It ended with the recommendation of replacing our entire 30 year old HVAC system. We didn't anticipate the full enchilada being necessary but it made sense to upgrade and get a fully functioning and much more efficient system. Carlos was extremely communicative and professional, as were his assistants. He worked with us on price and brand we desired, and even had his crew start at 6am on installation day to get the job done in a timely fashion and that worked better for our schedules. Talk about commitment to the customer! While we haven't had the chance to use the AC yet, we've been happy with the furnace during this recent "California cold snap". Thank you Carlos for your professionalism and workmanship. Will be recommending 5 Diamond to friends and will be back ourselves for our heating and cooling needs!
