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!

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.

After I posted a review online, they replied to it. They took no responsibility for the lack of communication and asked us to call them back so the trust could be repaired. Call them back?

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.
