“Very trustworthy and Steve ensured we had a high quality working product before he left. He was replacing our AC unit, but our brand new furnace (which we did not get from him, but wish we would have) kept blowing a fuse. Steve replaced that fuse at no charge and investigated why it was happening. We had a very old unit, so many pieces had to be replaced. Steve and his crew stayed into the night to make sure we were all set. Would highly recommend!”Kara P., New Berlin, WIProject: Install a Central Air Conditioning System
“I would recommend this gentleman wholeheartedly. He came a day earlier than the appointment and showed extra concern for my problem since I had a disable child living with me. Very nice gentleman and called back the next day to make sure everything was still working well.”Lynn E., Milwaukee, WIProject: Install a Radiator Heating System
