In 2022, Deljo installed a new two-component A/C system in our unit (including rooftop condensers) in very tight places. Before, during, and after the work, Deljo was efficient, communicative, tidy, and skillful. Deljo also did a no-charge inspection in 2023 to ensure that annual servicing could be fully completed. Deljo's office management and service technicians cared about our needs and worked to address them. We have confidence that Deljo will maintain that high standard over the years of our system.

Alan was fantastic! He was extremely helpful in walking me through questions that I had for the service he was here for (AC maintenance) & offering tips on how to get the best performance out of our system. He even took the time to walk through questions I had on other appliances unrelated to why he was there! Overall - I’m very impressed with the service we got from Deljo Heating & Cooling.
