EXCELLENT Based on 85 reviews Bob BerenguerJuly 31, 2025 Started per agreed upon date and finished on time Friendly staff. Fair price. Dan MaciborskiJuly 18, 2025 Thomas showed up promptly at the appointment time. He was very professional, very thorough, and clean! He was very attentive to leaving things how he found them and very conscientious of picking up the work site. The a/c unit now works as if it was brand new. Kathy AbellJuly 17, 2025 Tech gave timely advanced notice of their expected arrival time and worked efficiently to complete the job. Tom WrightJuly 15, 2025 I never suffer pre-appointment trepidation. I know they will come through in a fair efficient manner. Thanks again for your service today. I recommend Certified Air for everything from an annual service to a full replacement of your system. Our new hybrid Bryant system (installed last summer) was a great choice. With recommended modifications to damper our delivery duct lines the system is much more efficient than originally installed by builder.
