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.

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.

The lights flickered several times which was at least one time too many. Normally my Lennox unit shrugs that off but not this time. I called All Comfort Services today and they were able to send Monte A. on the same day. He's the man! All he had to do was be in the house and his aura was enough to bring that dead unit back to life! (Seriously!) He said he just checked the outside unit and it seemed to be blowing hot air indicating it was working. Honestly it wasn't working when I checked it the evening before - my aura must be old & tarnished. Like me. Good thing Monte's isn't. Just the trip charge - worth it. I've made a service appointment to get the oil changed and tires rotated on the furnaces and air conditioning unit and I'm certain whomever they send will bring the aura, too. We are comfortable once again.
