Installation went well and the installers were professional and even laid drop cloths to decrease any mess, as well as cleaning floors at the end of the job. The lead worker explained and demonstrated features of the system. I would use them again when needed."

He installed new duct work to the dormer addition, and I retained him for furnace replacement, and, later, addition of a central a/c unit. I appreciated his openness to questions, his attention to detail and his technical knowledge. He is a delightful person, totally devoid of b/s, and fully trustworthy."

"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.
