Welcome

Christensen & Wisnet, "The Good Guys" have been proudly serving the Fox Valley and surrounding areas for 52 years, with our family name going back nearly a century in the Heating & Cooling business. We are a proud 5th generation family business and we offer service, repairs, sales, and installation of Air Conditioners, Furnaces, Boilers, Ductless Air Conditioners, and Indoor Quality Products like Humidifiers, Air Filtration Systems, and new high tech solutions like the UVPhotoMAX or Orion ion generator.

Through our years in business we worked hard to earn respect of the valley by being honest, upfront, and "Good Guys". Our service technicians are friendly and skilled. Our installers work efficiently and install high efficiency equipment properly with pride. Our estimators are not pushy, both of them with several years of field experience will offer sensible solutions that make sense. You will be impressed.

We are proud to have one of the largest customers bases in the valley. You would be surprised of how many of your neighbors use us year after year for their Heating and Cooling system.
