"I’ve used Carlson Heating & Cooling twice and have been very satisfied both times. In 2024, I had them 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. In 2005, 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."

"They handled my boiler heating system installation and wall heater repair with great care and expertise. The technicians were knowledgeable, explained everything clearly, and made sure the job was done right. I truly appreciate their reliable and high-quality service."

"I've never heard of Perfect temp until today. I'm a new homeowner and my furnace went out. I used homeadvisor to try to find someone to help me. Perfect Temp had great reviews, was speedy to reply. They were very understanding to the urgency of my situation, explained the problem in detail and had my heat running within a very short time. Very friendly and very knowledgable. I would highly recommend Perfect Temp to anyone in need of furnace servicing."

"Harker Heating And Cooling is the best HVAC contractor we have ever worked with in 40 years. Their web site proudly says they are an “honest company with Midwestern values.” That is absolutely true. Their representative provided in-depth advice, answered our questions. and returned our messages. Their techs were knowledgeable, professional, careful, and friendly. They were on time, on call, and on budget. The service they provided for us over the years could not be better. So when the time finally came to replace our old furnace and A/C we selected them. Unfortunately, they encountered many unexpected problems installing our new equipment. Many more than they had anticipated for the job. But their representative pledged to address every one of them no matter how hard it was for them or how much of their time it took. And that is exactly what they did. No quibbling and no questions. They got the job done right. If you want an honest family contractor who stands behind what they do, and lives by those Midwestern values, then this is the company to hire. You will be glad you did.
