Is $977 to replace a defrost control board a fair price?
Project Details
My AC and thermostat went out. After basic troubleshooting, I called a tech who replaced a blown 3 amp fuse in my furnace/air handler. The fuse blew again, and the tech determined the defrost board was bad and causing the short. The company quoted me $977.00 for the replacement but claimed the part was on backorder until October, then offered a quote for an entirely new system. I will not be hiring this business. I ordered the part for $130 and am replacing it myself. We are currently using a portable AC for cooling.
