Carlson came…read moreover and after trying to save the air conditioner by replacing a part, the unit was pronounced dead. He called for the replacement cost and I asked for pricing on one size bigger, after we decided we need a larger unit, he order the replacement air conditioner for next day installation. He arrived exactly on-time for the appointment and increased the air conditioner capacity to fit the actual size. The appointment was finished under the estimated time and they were very courteous through the entire experience. While replacing the air coil, Mike showed me the location for the furnace and humidifier filter allowing me to change it myself. After replacing the air conditioner and removing the old one - he made sure that I had the information needed and made sure that if we had any questions to call his office. Great service and great/honest serviceman. I'll not call anyone else for future HVAC matters and wouldn't hesitate to only shop here when it comes time for me to replace other units. Second great round of service - last time was middle of winter and arriving home from out-of-town with no heat, he was wonderful replacing heater during the negative temperatures.

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.

I had two furnaces installed roughly 15 years ago. They worked fine. The price was reasonable. I…read morecalled them back recently And they didn't show much interest. I got no consideration as a former customer for repeat business. I guess my heat exchanger hadn't been registered Or something to that effect. If it wasn't registered at the time This stated warranty will not be honored. I thought my contractor let me down I thought they should have seen to it instead of expecting me to do it. Putting a new furnaces is a highly distracted Consumer experience And with the amount of money involved the contractor should be taking this responsibility. I tried to give him more business but I was just treated like they treat everybody else so I had to go to a different contractor. It's hard to get good info but people should check BBB and check datcp State of Wisconsin consumer protection. That's about all you can do because just about everybody's out to screw you one way or the other. You know unless you know somebody personally.
