My business plan and experience has always been under promise, over deliver but I made sure my horn got tooted loudly when appropriate. After looking up the specs on the furnace I received, I was pleasantly surprised to find that my new furnace exceeds my expectations. And yet none of this was mentioned by the company, prior to or after installation...c'mon guys, brag a little...I know you're good and so is Lennox but a little rah-rah-rah couldn't hurt, could it?

High quality work from service desk to installation techs and extremely fair price on unit. All have been courteous and friendly and 100% recommend them.

Excellent work Mike!…read more Mike done a few jobs for my elderly mom. He replaced her front door with a new secure one and when it came time to sell the farm he replaced the GFCI outlets in the house and a few receptacles in the attic and barn all to meet code so we could sell on time. His appointment time frame was fast and arrived on time the day he did the work. He finished in a few hours and his pricing was more than reasonable. He did an excellent Job, thanks Mike!

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.
