Our tech, Zach, arrived as scheduled and was wearing a face mask, shoe covers and gloves. He was careful about social distancing.This was a regular contracted call to service our AC unit, but he suspected a leak in the cooling coils (ice had formed on the bottom fins and tubing). He advised we would have no AC until he could find the leak, but he had another scheduled call.Fortunately, he was able to return after his last call. He ran a leak test and found the AC coil would need replacing, but could not be scheduled until the parts came in. He completed our service check, adjusted our heat pump to give us some cooling (90+ degrees all week!) and cleaned up everything before leaving.We were charged only $85 for the leak test and given a fair quote of about $1,300 to replace the coil and recharge the system (our parts are still under a 10-year warranty).We hope Zach is assigned to our repairs when the new coil arrives. He was thorough, very friendly, professional and efficient. Nelson Comfort is lucky to have Zach on their team!
