Very impressed with the quality of service we received from Della-Mora HVAC. The owner (Mike Della-Mora) was very knowledgeable, professional, and friendly. He arrived on time, and had our A/C unit fixed quickly. Very reasonable pricing (much less than I was expecting). He also provided valuable recommendations to help prolong the life of our old unit. We will be using Della-Mora for any of our heating & air conditioning repairs in Chula Vista going forward. Thanks Mike 👍

Della-Mora Heating and AC did a great job following through on a repair for one of my real estate clients. They worked closely with the property manager to make sure the repairs could be completed.

Michael is very professional and knew exactly what needed to be done to fix my mom’s boiler radiant heating system. This was no easy job, as it took me almost 3 months to find someone to even look at what was wrong with the heater. His knowledge and problem solving expertise helped us get heat back into the house.
Thank you so much and my mom is very happy and loves her warm house!
