"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. Doug and Margie King Mount Horeb, Wisconsin"

They were not the cheapest of the quotes we received, but the excellent service was worth the small amount "extra" and the equipment they sold us appears to be outstanding. I would happily hire JB again."

"Very smoothly. The contractors where very personable."

"Zach not only mowed the yard, a hill i hate, but also made sure any clippings on the sidewalks or driveway were taken care of. He was also kind enough to mow the vegetation that had sprouted between some cracks in the driveway."
