We aren't just a San Diego HVAC Contractor, but a family owned business.

Why the importance of family owned? Why does it matter? It matters because it means we are long term, and we care at a level that is hard for large corporations to understand.

We are a San Diego HVAC contractor who will be here tomorrow, and the next day. Not a fly by night dealer gone when you need us most.

Family owned also ensures you will experience a level of customer service that is unique to family owned companies. We understand the importance of reliable and efficient air conditioning, heating and indoor air quality products for our own homes and office, and we know that the same is important to you.

For this reason we provide our San Diego area customers with the latest in heating and air conditioning technology - products that we would trust in our own home.

We appreciate your interest, and hope that you will call us at (833) 353-4822 if you need further information. Trust your San Diego air conditioning and heating needs with us, and we'll make sure our family keeps your family comfortable.


We could not be happier with our choice of 5 Diamond. Carlos and the entire group were great. We had 3 Fujitsu Mini splits installed and an old wall heater taken out. The job took a few days to complete and everyone that worked on it was friendly and courteous. The installation looks great and we are extremely happy with the product and the work they did. At the time of installation they were unable to test the units ( we were having the house rewired at the same time) so we did have a small problem with the condensation lines once the units were up and running. It of course happened on Labor Day weekend. We contacted them after hours and left a message, the next a.m. they were out there to start fixing the problem. It ended up taking 2 days of the long weekend to resolve but they were there to make sure it was takin care of. Trust me when I tell you I will never use anyone else except 5 Diamond for our HVAC needs!!!
