I've used Carlson Heating & Cooling twice and have been very satisfied both times. In 2024, I had…read morethem inspect my furnace and AC. They arrived on time, were professional, and gave my system a clean bill of health--without recommending any unnecessary repairs. Last week, when my AC stopped working, they quickly diagnosed a dead compressor and recommended a replacement. Impressively, they waived the $225 charge for the initial visit and parts. The replacement was completed on schedule, exactly within the estimated cost. The technicians were friendly, informative, and professional throughout the process. They also cleaned up thoroughly, leaving no mess behind. I trust Carlson Heating & Cooling completely and will continue to use them for future service. I highly recommend them to anyone needing a system check-up, repair, or replacement.

Mike was just awesome!! I will be calling him again for my cleaning in the spring. His prices are…read morefair. He came over to fix a problem with my furnace. We thought we had fixed it. I needed to call him back and he came back to fix it after his day was over. A part needed to be replaced. He used the service charge towards the price of the part. His work is really quality. Very conscientious. Will be calling him again!!

After a great review for our first experience we had the exact opposite with our AC unit. Randy…read moredoesn't call you back timely if at all. Awful service with this company starting in May to date! His employee Dan is fantastic. I would NEVER use Randy voluntarily ever again. Our furnace looks horrible, taped together front. They were supposed to come back and put a different front on it but haven't. Many many messages left...with few call backs.

Then, first thing in the morning of finding a contractor that will put you on their list and maybe see you today because of all the other people in the same boat. Then thinking if they are reliable? Are they going to charge too much? That is when our family was lucky enough to find Tina and Rockton Heating. Everyone expects professionalism and to be treated right, not always the case. Provide your family with the best care and call Tina now, even to put your mind at ease with a furnace check. Don't waste your time and money with anyone that does not have your interests first. Rockton Heating & Air Conditioning is who we trust and will always recommend.
