Thank you to Steve at Payless Cooling & Heating. When our R-22 unit bit the dust last month he came out and gave us an honest assessment and helped us to make the decision to upgrade our condenser and coil to R-410A. All of the advice he gave me, and the estimate for repair was right in line with what I was told to expect by a close friend who has HVAC experience. Last night we could not get the A/C to come online, and we were concerned that it was somehow related to the work that had been done last month.
Steve again came out, and determined that the problem was simply a loose wire nut behind the control board. He fixed it at no cost, which we appreciated as the R-410A conversion was a large unexpected expense for us. We chose Payless due to their reputation, and based on numerous positive online reviews. Our experience with them was excellent, and we would highly recommend them to any of our friends in the Houston area.
