Great service!

Our HVAC unit had been down since mid-May. We have a maintenence contract, but we'd been away from home frequently and didn't have time to get a repair person in to check it. When Diego got here he was able to determine the problem, correct it, and complete the maintenance work. Diego was very patient answering my questions and even suggested preventive measures to protect my HVAC investment going forward.

Always Great Service!

We had a service call today and Certified, as always, sent a friendly, competent, thorough technician to address our issue. Diego identified the problem quickly and explained it all to me in detail. And he was just as kind as could be. I recommend this company to anyone who needs heating/ac work. We are loyal customers for sure.

Routine friendly service on the heat pump

A good service encounter with Matteo of Certified Heating and Air. He arrived early in the window, was friendly, did a bit extra while waiting for the filter to dry - swept out the dryer vent. The routine for this service includes before-and-after cleaning pictures of the filter taken by technician which were shown to me at the transaction. Not a full 5 star review because this appointment was rescheduled because technician was overbooked last week.
