3 Best HVAC Services in Madison, WI

My former business was operating chain restaurants, so, over the years, I have used many heating and cooling service providers. Without doubt, Harker Heating and Cooling customer service is the pinnacle. Great communication before the service call. Our Tech Adrian called us as he headed to our home, and he was right on time. Adrian first discussed the scope of the service with us before he began, and briefed us on what he found and discussed our options. We were left with a full written report. The company then checked in with us after the service call to see if we had questions or concerns. Bottom line, if you value service, Harker won't disappoint. BTW, the price was competitive. Overall, first rate.

I recently had Harker Heating & Cooling fix my air conditioner, and I can't praise them enough! From the moment I called, their team was professional and attentive. They quickly scheduled an appointment and arrived on time. What impressed me most was their commitment to going above and beyond. Not only did they diagnose the issue swiftly, but they also took the time to explain the problem and offered practical tips for maintenance. The repair was completed efficiently, AC has been running perfectly ever since. The technicians were friendly and respectful, ensuring everything was tidy before they left. I highly recommend Harker for any heating and air conditioning needs—truly outstanding service!

Lucas is a very friendly and personable technician for Harker Heating and Cooling. He is timely in his arrival and does an excellent job servicing my air conditioner and furnace. He thoroughly explains what needs to be done and does the work very efficiently. Thanks Lucas. And I appreciate the reminders twice a year for scheduling the service needed for my heating and cooling equipment and the discount for scheduling accordingly.

I've been using Cardinal for over 30 years and they always have been top notch. We've had new A/C's and furnaces installed and they have done a few plumbing jobs for us and we have been satisfied all these years. Today Ken came out to fix a broken shower spout and was in an out in about 30 minutes. Great job and as all Cardinal employees very friendly and polite. Thank you Rick for all your help over the years.

Our experience was great from start to finish! Easy to book online and Cardinal updated us every step of the way via text and a phone call to let us know a plumber was on the way. Austin was friendly and professional and stayed to figure out our problem even though it wasn’t what we originally thought. He also suggested future maintenance to keep our home running smoothly. Highly recommend!
