Very good experience with McCullough Team and their technician Ryan Lake. I had signed up with them for their Premier Comfort plan last month and AC was turning off randomly. Their tech came in at very short notice and cleared the drain system and AC started working. Just when it got hotter, the blower decided to fail so I contacted them. Tech came on a weekend, diagnosed the issue and put in a request for parts right away. I was dealing with am emergency situation at home and could not approve right away. Home warranty covered this expense but I did not have time to coordinate things. Once I got approval, they came and fixed it right away. I appreciate their promptness and response emails from their customer service manager when she heard about my predicament. The only tough part is getting a hold of someone to talk to. 'Jane' , the voice assistant is very smart and responsive but takes a few tries to tell her that a human being is required. All in all a great experience - I would highly recommend this company for taking care of heating and cooling equipment.
