"The yearly service agreement I have for inspection of my furnace and central air was a great investment. Jim a furnace tech arrived today on time per great communication with him and his office. The inspection was far greater than I expected for the cost. The tech was pleasant and very good at his job. Being a retired field service technician I’m a good judge and was more than satisfied. I highly recommend Kettle moraine as over the years we have had them replace the furnace and also our central air. Every experience has been a pleasure and without one complaint."

"I spoke with the owner at 2:30 in the afternoon and he was here for an estimate at 5pm. We booked an appointment for a new furnace that day. We had problems with the old furnace and the owner worked on it, attempting to replicate the problem. A Tech was sent out the next morning (free of charge) to get us through until the new furnace was installed 6 days later. Everyone we dealt with was VERY knowledgeable, explained each step to us, were expedient and very thorough. Pricing was excellent. This company will be the only company we call for ANY HVAC work. HIGHLY RECOMMEND!!!"

"I had the Team out to perform and AC service and Furnace tune up. With such great service and comparable pricing I ended up moving forward with duct cleaning services. The guys were friendly and professional they were also nice to my doberman."

"It went fine. They were friendly. There was no additional charge apart from the big deal but he said there were close to having an extra charge because the vent line was longer than expected but it was just in the parameter. The scheduling was fine."

"Politely said, Sparky is the boss.
We needed electricity and HDMI ran from a cabinet in our great room up above our fireplace so we could mount a TV. Also needed cable and electricity ran to a wall in our master bedroom so we could mount our TV on the wall.
Sparky showed up on a Friday afternoon, five minutes early. Assessed the situation, and before he left, said he would look into how much parts/etc would cost, and he would call me with a bid. Sunday night I received a text from him with a bid, we set up a time for him to come for the install on 8/22 at 9am.
Sparky showed up at 8:59, and got to work. I came home from lunch to outlets installed where I had asked, cable ran, everything was great. He could not find the specific outlet cover for AC / Cable, but it will not be visible once the TV is mounted, so it is not of real concern.
I was a little uncomfortable mounting the brackets for our TV on the walls, as the studs were located in odd places - and I didn't trust myself to mount a $1,000 60" plasma anywhere that wasn't on a small stand. ha!
I asked if he would mind installing the mounts if I kicked him some extra $$, and he gladly obliged to stay longer than he had originally intended. He even went so far as to use his own screws/mounting bolts that were FAR superior to the ones that were provided in the kit.
Couldn't be happier. Should we plan on doing any other electrical work / lighting in the future, Sparky will be our first call.

"The installation of the new furnace was good. We have not had any issues with it. The workers were pleasant to deal with. The salesperson was helpful and advised me what furnace I should install. I was happy with the service by this company."

"They came out and looked over the A/C unit. I told him it makes a very loud banging when it starts up and that the company who installed it told us that was normal and it was working fine. Once he was done cleaning the unit, he went to restart it and it tripped the breaker. So he took it apart and found that when it was installed, someone had pinched a wire, cutting the insulation and causing it to short out on the frame of the A/C unit. He fixed that, reassembled the unit and restarted it. It's still a loud start, but not nearly as loud as it was. He informed me that our A/C is a builder grade model and unfortunately it's not the best on the market so it's going to be louder than we would like. Once he was done working on the A/C, he came in and took a look at our furnace to make sure it wasn't hooked up wrong also. Definitely will be calling on Faithful again."
