I live in Milwaukee and have a home up in Shawano County. My home is equipped with a Nest…read morethermostat so I can monitor the heating conditions in winter and turn on the air conditioning before I leave town in the summer. I recently noted my Nest was offline for 4 days which was unusual so I decided to begin my 3 hour drive north. About half way there I got an email from my Nest that the safety temperature of 45 degrees had been reached in my house so I knew the furnace was not working as the temperature should be maintained at 55 degrees. While approaching Fond du Lac, I called Knope to see if they could get someone out to check on my furnace. This was around 2 in the afternoon that I made the call. I explained that I was in route but that I would have a neighbor open the house if I was not there. Knope said they would call me back. They called and said they had a technician on the way there. Within the hour they called me back and said that I had a bad heat exchanger. The tech and gotten the heat going and I should be good for the night and that they would be back in the morning to replace the unit. But the best news of all was that this was covered under warranty. I was pleasantly surprised as the unit was almost 10 years old. I was still in Appleton when I got this news so I can't say enough about how pleased I was with Knope's service. The next day the new unit was installed and is working perfectly. They did an excellent job. I would highly recommend using Knope Heating and Air Conditioning as your service provider.

The furnace in our Northwoods home died while we were away. Fortunately, the weather was such that…read morenothing froze. However, we needed heat to live there. Other companies gave us long lead times to get the furnace fixed or replaced. Tom from Gerondale Heating came out to check our furnace that same evening. He showed me the issue and said we either needed a burner replacement or a new furnace. The old furnace was undersized and a replacement, for a little more money, gave us a proper size and a 10 year warranty. We opted for the new furnace, and Tom Jr. brought one up from Green Bay and had it completely installed and working properly by noon the next day. Great service, great product and friendly people as well!
