Get matched with top heat pump repair or service pros in Saint Charles, MO

"The service technician, Chris Clawson, was professional and thorough, finding only one item that may need to be replaced. He didn’t push on that replacement at this time. As part of my membership, there are no charges."

"Great job with AC repair!"

"This company was excellent all the way around. The staff member who contacted me was very nice and helpful. They were able to come out the same day (I did not have heat). They sent me a text message with a picture of the technician which I thought was an excellent feature. The technician, Jeff, was very nice and extremely knowledgeable. I would definitely hire them again because the work was top quality and the cost was fair and reasonable."

"This company was extremely responsive and professional.  Marc was very knowledgeable and worked hard to get warranty coverage for my repair and to get my family back in our home quickly, as we had to leave due to no a/c during a heat wave. I met with him at 11:00 and there was a new unit installed by 4:00 that afternoon.  I would highly recommend this company."

"Robert did a great job in checking out my furnace that wasn't operating and provided me with the next steps I needed to take with the gas company. I can't say enough good things about Robert. He was so extremely helpful and informative. I'm a delighted customer and am glad I have Dunn for my heating and cooling needs."

"The service was very prompt! The plumber was able to fix all the things I needed & made some good suggestions!"

"I really appreciated the phone calls that kept me apprised of where the repairman was and how much longer it might take for him to get to my house. The repairman was really nice and he was not only able to figure out what was wrong with my dryer in no time, but he was able to repair it very quickly when the parts arrived. I would definitely recommend them and I will call them if I need another repair."

"This company goes above and beyond! Very professional and honest. Matt replaced my AC and furnace and did a fantastic job. I will definitely be using them again for all my service and maintenance."
