Excellent service.

One of our air-conditioning units quit cooling the morning before having out-of-town guests arrive. Michael Fernandez was on site quickly, diagnosed the problem and a new part installed. Michael was so polite, extremely knowledgeable, thorough and professional. He also wore shoe covers in the house to keep our floors clean. This was such a good experience. Thank you Michael and thank you Chaffee Heat and Air!

The only company I have used for 14 years! Michael called before coming today. He was very professional, well spoken, courteous and skilled. Gonna miss Rex (former owner ) but glad to see Aaron (new owner) is carrying own the great service and tradition of employing veterans! Go Navy!

Called in Friday as a HVAC friend told me my unit needed to be cleaned. I spoke to three companies and felt the first two were looking for ways to get more money BEFORE they even saw my unit. I spoke to Aaron at Patriot Mechanical who advised me of a service fee what it would cover and then told me of their service contracts. I had a horrible experience with a service contract previously with a different vendor. My service man Michael was on time, explained how the unit worked, was very through, had the work completed as previously stated and explained the benefits of a service contract. This company is highly professional with work done right and timely. I highly recommend them and my service representative Michael.
