Our furnace suddenly stopped blowing warm air, and we were freezing! Conner quickly diagnosed the issue as a bad blower motor and had it replaced the same day. He explained everything in simple terms and even checked the rest of the system to make sure we wouldn’t have more problems. Super professional and friendly—highly recommend!
