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 was really excited to have Mack out to quote a replacement furnace/AC, based on everyone's…read morecomments on Reddit, Nextdoor, and elsewhere. I really wanted someone local, independent, and that I could call and they'd answer -- and be honest. But... I was incredibly underwhelmed. I was after a full replacement system, with a slight preference toward replacing the AC unit with a heat pump. I also wanted a two-stage system due to slight temperature imbalances in the house. He very quickly dismissed heat pumps, saying that they're "worthless" in Wisconsin, and he also didn't entertain the idea of a two-stage system. I asked about going from a 1-inch filter to 4-inch, and he said, "No, I wouldn't do that. The thicker filters restrict airflow too much; I would just get a higher quality filter." This is just blatantly incorrect and the exact opposite is true. 1-inch filters with higher MERV ratings are what restrict airflow. I also had a 45,000 BTU furnace, which had had no problem heating our home (and it was 20 years old! -- both the unit and house), but he very quickly said, "Oh, that's too small. You should get an 80,000," without taking any sort of measurements, asking any questions, or looking at the rest of the house. You can't do a load calculation based on...nothing? And you can't just nearly double furnace capacity without causing issues (mainly, that it's going to short cycle from being oversized). And, as mentioned earlier, it wasn't going to be a two-stage furnace, so it would have run at that full 80,000... Maybe he's good at repairs (I don't know), and maybe he's well priced (he came in second cheapest out of the four bids I got), but these were all just fairly big red flags for me that he wasn't a match for me for doing a new install. I got a two-stage heat pump and two-stage furnace setup from elsewhere and so far am very happy!

They told us that it was a blower motor and it would cost about $1500.00 to get us up and running. They said we were better off getting a new furnace costing about $6,000.00. We decided to check around and decided to call seasonal survival. WOW. I called and they were able to come out later the same day. It was the circuit board. He happened to have one on his truck. $375.00 and 20 minutes we are up and running! We even tried to give him a tip and he said nope, we don't do that. If you need any heating or plumbing issues do not hesitate to give them a call!

He told me that we didn't need a new thermostat, but the installers would know more and would install one if necessary. Our install went great, but a few days later we noticed large pools around the unit and called Tom just to be sure it was normal (new homeowners). He seemed concerned and said it is not normal and he'd look into it right away. I had to call HIM back after waiting almost a week to hear back. His response was, "oh that's perfectly normal." Not sure what changed, but would've been nice to know instead of worrying. Fast forward to the first day we turned on our heat. Every time the heat kicked on, the AC unit also turned on. I'm no expert, but I knew that wasn't normal. So we called and made an appointment for someone to come look at it, because again, they seemed concerned. When they called to confirm my appointment, the lady on the phone said that we didn't need our appointment, we just need to turn our tan off of auto. Well, it kept happening, so I called AGAIN to make a NEW appointment. The guy who came out was very polite. They thought someone who installed made an error in electrical. After searching, he decided it needed a new thermostat. Surprise, they only have one style available and it's $250. Then he tells me I owe an $80 service call fee. I don't expect everything for free. However, no one ever said we were having connection issues with the thermostat at the install, and they thought they made an error in the install, so I was not expecting to have to pay that. If my mechanic thought he made an error on my car; he wouldn't charge me another diagnostic fee. So I called and just explained my thoughts behind this all, and Tom heard me out, but wasn't very helpful. He said he would talk to a manager and get back to me on how to resolve this. I have yet to hear back and it has now been two months. Great field employees but horrible customer service in the office.

(The technician they sent was very good.) We had the tank filled to a certain level recently, so it was easy for me to estimate the amount that was lost. But it was a struggle dealing with Craig, the manager. He offered to replace a much lower amount, and said that it was more than fair. I disagreed and told him how I came up with the amount that was lost. Craig wouldn't budge, and refused to let me talk to someone else. This one star review is for cheating us out of the gas that was lost because of their faulty equipment, and for being so hard to deal with.

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.

Devon and Caleb were personable, knowledgeable, and efficient. We were happy with their service.

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.

Olson shows up and went through a very thorough diagnostic process to determine why my furnace doesn't want to furnace any longer. Turns out the control board was bad. Normally not the end of the world, these things happen. What became the real issue is that my furnace was old and getting a control board was going to be a problem. What my malingering furnace didn't realize is that Olson was on it! He apparently had a board that was an exact match that came from a tear out that had preformed the previous week. He set us up on emergency heat until the next day, when he showed up to install the replacement. Now he could have told me that I was just "duct" and that I would need a new furnace $$$$$. But that's now how they conduct themselves. Fast forward ten years. My AC stops working. Of course during a brutal Wisconsin summer. You know the ones where when you wake up the windows are completely covered in condensation, like it's raining. One call, that's all it took. Olson is in the job. Replaced my aging AC system with a great unit that was priced right. Needless to say we be chilling. I really cannot emphasize how thoughtful, thorough, and professional the work was completed. And it was on time and under budget. That you Olson for such great service throughout the years!

We have an infant and a cold snap was heading in, so I looked up community recommendations and everyone said to call Mike at Olson. I called and left a message explaining the issue. He called me back right away and said he could come take a look at the end of his day, that same day! He came and analyzed our furnace, and everything that was wrong with it. He was very honest and helpful, which I appreciate. Not a hard salesman, just trying to help our family make the best choice for us financially. Basically, we needed a new furnace. He couldn't get us in until a few days later(we were just surprised he had furnaces on hand!), so he reset the furnace to get us by until then. He installed the furnace in just a few hours, and it was working like a pro! But just a few days later, we noticed our room upstairs wasn't getting any hot air from the vent (our house is old and doesn't have enough vents as it is), so we called Mike. He came over that same day again and looked it all over. Turns out it was a simple fix and the heat started coming through the vents again. But that just shows you the attention he gives to each customer. We will definitely work with Mike on all heating issues going forward, whether it's this house, or the next.
