Miguel R. - happy Core Comfort HVAC customer in Mesa, AZ

"I installed my own Daikin unit in my garage and wanted to make sure I didn't mess anything up. The tech came out, checked my flares, ran the vacuum test, and got me up and running. Total peace of mind for $600."

Diane K. - happy Core Comfort HVAC customer in Scottsdale, AZ

"My husband and I DIY'd a mini-split in our bedroom. We weren't sure about the refrigerant side of things. Core Comfort certified our install, did the nitrogen test, and released the refrigerant. Professional and friendly."

Tyler B. - happy Core Comfort HVAC customer in Gilbert, AZ

"I'm handy but not an HVAC guy. Having a licensed, EPA-certified tech come verify my work was worth every penny. He found a tiny leak at one of my flares, I re-did it, and he retested. Good as new."
