We called them several times and left messages to their sales person Amber. She never gave us the courtesy of a call back. We felt we needed to wait since they were working on a few options. I wish we didn't because a pipe burst and there is now water everywhere. Our insurance won't cover any restoration because the heater was out. One may reason this is not their problem, since we could have called someone else. I say this is terrible, couldn't-care-less customer service on their part. We used them for several jobs before. I have no idea why they didn't follow up with us. If they didn't want to do the job, they could have said so. Ended up paying a very high price for being a loyal customer to them. 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? We did, many times. Not anymore.

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 woke up to no working furnace last Tuesday. We called one company. The service call was…read more$154.00. Ok, understand. 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!

The first time I called them, Stan showed up at 07:50 a.m. for an appointment at 08:00 on a Saturday - but he hung out in his truck and waited until eight on the nose to knock on the door. I had a clog in my sink drain that was too far down for my snake to reach. He measured from the sink and the main, cut out a bit of pipe, cleaned it out, and then installed a T joint with a plug I could take out if I needed. Now, there's no part of the pipe I can't reach with the snake. That was the first of many great interactions. At this point, I tell them what the problem is, and they come fix whatever it is, and I pay them. I trust them so much that I don't need to talk to them before they fix something.
