Our AC went out and Robbie was able to come out same-day and diagnose the issue. He was really thorough and explained everything. Sadly the manufacturer dropped the ball on the order, but A-1 was very transparent and got it taken care of. Once the part came in, Robbie was back out promptly, made the repair, and our AC is back to fighting these record-breaking temps.

I would give them 10 stars if I could! We had other contractors come in and tell us we needed a whole new ac unit for $5k-$20k when our ac stopped working. A1 literally saved us thousands of dollars by fixing our ac unit and being honest about what was wrong. They are now our go to HVAC people!
