HVAC Service Covering All Makes & Models

As your trusted San Diego HVAC contractor, we understand heating and cooling. We know it inside and out, and we naturally have certain manufacturers who we trust for reliable and efficient performance for our customers. However, when performing repair and maintenance, we are qualified and able to service all makes and models of heating and air conditioning equipment. We know the strong and weaker points of different equipment, and can help you utilize these to your advantage as much as possible, so that you experience efficient indoor comfort control.

Preventive Maintenance

We are constantly urging our California customers to perform seasonal maintenance on their systems. Compare your heating and air conditioning system to your automobile. Some attention is required for proper maintenance, else you'll end up with the need for pricey repairs. Just like fuel efficiency suffers in a car when it isn't maintained, your energy bill will feel the affect of a neglected HVAC system.


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!
