Della-Mora just finished repairing my 26 year old air conditioner and I couldn’t be happier! They went above and beyond trying to locate parts for my out of date system. They even installed a temporary motor so we could get some relief during this heat wave while they continued to look for the correct part. They really cared about us and our problem even though they were very busy.

Absolutely, 5 out of 5, would even go above and beyond and say 10 out of 5 stars. We needed urgent assistance and that was received, the work was done incredibly well & the price was beyond fair. I highly recommend this business and would use them again in the future. It’s rare to find such great service nowadays. Grateful to have found someone good!

I don't write many reviews, but Michael and the entire Della-Mora team absolutely deserve this one. Throughout our extensive home renovation, I've dealt with dozens of contractors across many specialties. Michael stood out immediately for his honesty, integrity, knowledge, and genuine commitment to customer service. He drove from Chula Vista to Carlsbad to inspect our HVAC system and took the time to carefully access and inspect the difficult-to-reach evaporator coil and blower motor. After doing so, he honestly told me that **neither needed to be cleaned**. He could have easily performed the work we had scheduled and charged me, but instead he recommended that it was unnecessary. I even offered to pay him for his time and long drive, and he refused. He was also incredibly knowledgeable about our older HVAC system and caught an issue with advice we had received from another company that could potentially have damaged our exterior unit. He clearly knows his craft and, more importantly, puts the customer's interests first. Michael told me he wants to bring genuine customer service back to the industry, and he absolutely demonstrated that. His integrity isn't just something he says—he proved it by choosing not to sell me unnecessary work. I've already referred him to my family and will absolutely use Della-Mora for future HVAC needs. If you want an honest, knowledgeable, and genuinely customer-focused HVAC company, I highly recommend Michael and Della-Mora.

We had our AC stop blowing cold air on a Saturday. They came out on early Sunday AM and had the system up and running. It was a capacitator that they replaced for a fair price. Highly reccomend.

Della-Mora saved my summer! Our AC was not blowing cold and seemed to be running all day without ever feeling cool. Della-Mora came out right away and within 10 minutes was able to see the issue. By the next morning we had a quote for the repair and they scheduled the repair. Each day without AC made it difficult to sleep and even cook, so I appreciated the prompt response. Now my home is comfortable thanks to Della-Mora!

Michael was in our neighborhood working on our neighbors AC. As i dove by i approached him after he finished with the neighbor's house if he could drop by and give us a free estimate to service our AC since it was an older unit that was on the fritz no longer pumping cold air. He said sure! He came by inspected the unit i turned it on he quickly found and resolved the issue it was a breaker issue, he later said that the R-22 was sufficient enough and educated us on how older AC functioned Michael was highly knowledgeable, friendly, polite and professional. Lucky me all free of charge since he was in the neighborhood servicing the neighbor's house. Thank you, Michael in a world of takers you are certainly a giver. I Highly recommend this guy!
