After a few days, my wife and I found out that our AC furnace was not cooling down our house, instead of going from 75 during the day to 72 during the night (as scheduled) we were reaching 80 and the furnace was working non stop!
At 10:00pm before going to bed we decided to call Wisconsin Fuel and left a message on their voicemail. The next morning at 7:30am, the customer representative was calling to schedule an appointment for the afternoon. At 1:00pm Dwayne called my house to see if anyone was there before sending someone. I called him back and not even 30 minutes later (maybe 15) someone was there. He found right away the problem ( a big leak of refrigerant) and while he was fixing it, explained to me how to take care of the system and what I was supposed to pay attention to to detect any malfunction or problem. He was really friendly like Dwayne and the lady who called in the morning.
I would recommend them without a doubt and I wish other companies could have such a nice, friendly and reliable employees.

5 stars for them, nothing less.

Having to conduct business with them long distance and on the phone for repair with a swimming pool heater they were great. They were able to take care of finding the problem and fixing it right away. Would for sure recommend them.

Had a few new vents put in when we remodeled the basement. They were in and out, no mess, and the job was done right (as far as I know). The rooms are heated and vented, so I'm happy.
