Happy DIYers Across the Valley
Real homeowners who installed their own mini-splits and let us certify the results.
"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."
Miguel R.

"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."
Diane K.
Scottsdale, 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."
Tyler B.
Gilbert, AZ
"Flat $600, no surprises. The technician was on time, checked the communication wire, measured voltage, and walked me through everything. I sleep better knowing my install is safe. Highly recommend."
