I've worked with Andy's several times -- Kevin, who may be the only guy? -- and he's great. He…read moreclearly loves solving problems and I really get the impression he's honest. The first time our furnace was leaking water. He fixed it for not much money (I don't remember how much), warned us if it happened again we'd probably have to replace it, and that was like a year or more ago. All has been fine. The second time was the first really hot day of the year. Our AC stopped working. He came out right away, did a great, fast, and very competent job, and fixed our problem for $200. I trust this guy.

Expensive service call yielded zero results. We have two CO detectors in our house, one upstairs,…read moreone in the basement. Both went off within seconds of each other just after I turned up the furnace in the morning. Bethke sends a tech out, I need to wait there and miss work, so that's not helping. Guy gets there, immediately makes up his mind that my detectors are faulty because they are old. Does a simple check for CO at the heat exchanger exhaust and the outlet into the ducts and comes up with a low CO reading. 20 mintues later, I'm $240 lighter with no real answer as to what happened. I checked my CO detectors later and they were working. So... I paid $240 for a half-assed, incomplete diagnostic by a monkey with a 5-gas analyzer. If I did that as an auto mechanic, I would be through. Do yourself a favor and call another company.

A little while back, we noticed that our furnace was not kicking on, and the temperature in the…read morehouse was dropping quickly, as it was below zero outside. Yay Wisconsin! We called a couple of places around and they told us we were out of luck for a few days, but Bethke's dispatch team was really accommodating and had a tech, Mike, at our house within less than two hours. Mike was extremely knowledgeable about the issue at hand and was able to fix it quickly. He also explained to me everything that he did, and I feel confident that I could do it myself now if it came down to it. He also gave me some helpful reminders about maintenance. I thought we were going to pay an arm and a leg, but the bill was the best part. Incredibly reasonable prices for lightning fast and thorough service. I would call these guys again in a heartbeat, and I think you should too.

After pulling everything out and drying it up, we found it was leaking from our garbage disposal. Fortunately, we are members of the Cardinal Care Club, so of course we called Cardinal. I made the call before 7:00 am. Cardinal called me back within the hour. A short time later, I was alerted that a Plumber was on the way. Ken Yager showed up & did a great job! He gave me lots of options and explained different benefits of each. He really knows his stuff. By 9:10 am Ken had completed i still, cleaned up & was on his way. Well done! This is one more reason we are Cardinal Customers and Care Club Members. That isn't going to change anytime soo

You can tell that they are trustworthy people that do a thorough job, and care about their work.

We will absolutely use this company again.

I thought I needed a new furnace because of a failure occurring in my current unit. I contacted…read moretwo companies and received quotes for $2000-$3000 for the repairs. My furnace is 12 years old and not inexpensive so I was not very happy about this. It was a coin toss as to whether to fix or replace. I called 5 local companies to receive quotes for a new furnace and they were $6,000-$8,000. OK was the last company to come in. The salesman, who is very knowledgeable and surprisingly honest, told me my furnace could be repaired for under $1,000. He could have just quoted me for a new furnace like all the others but didn't. I was thrilled. Josh, who had 30+ years experience, came in, found the problem, and my bill was $230. Who does that? I hope something else breaks so I can feel this good again.

Special note about Mike Hoffer (the owner), he was incredibly helpful, responsive on the first or second ring of my call and assisted us choose a unit and answer many questions through the weekend; and they were able to get a new unit installed for us within 2 days. It's a small company with a small crew but their customer service was excellent; pricing seemingly competitive. I definitely recommend this small but very competitive for HVAC system assistance.
