My heat pump started making a loud noise and shaking the whole house while running. I submitted a work order through my home warranty (Old Republic) and was referred to Cool Blew. I had never heard of them so I looked to Yelp and saw the good reviews. Johnny showed up on time and even covered his shoes when entering my home. He worked on my system and had the problem corrected quickly. I will request Cool Blew every time I need service.
