Welcome

Christensen & Wisnet, The Good Guys, have been serving the Fox Valley and surrounding areas through the decades. We are a fifth generation family business, and put a huge emphasis on customer service.

We have worked hard (and continue) to earn the respect of the valley by being upfront, honest, and "Good Guys". Our service technicians are friendly and skilled. Our installers work efficiently and with pride. You will be impressed.

We're working hard to be the Heating & Cooling company of this century. Our customers enjoy conveniences that others don't offer, like online account access, live service call status, self-service scheduling, and we were the first to offer conveniences like online bill pay.
