Welcome to the Good Guys!

We have been serving the Fox Valley and surrounding areas for 50 years, with our family history going back nearly a century in the HVAC trade. We are a proud fifth generation family business offering servicing, repairs and installation of residential and light commercial furnaces, boilers, and air conditioners.

Over the years we have been known for our impeccable quality, good-natured technicians, and our upfront pricing. Our reviews, referrals and customers say it the best. We are small enough to care for you, but large enough to be there for you now, as well as into the future. We are trusted by over 28,000 homeowners in the valley and we grow every year thanks to customers sharing their experiences.

Furnace Service and Repair

The Good Guys work on nearly all brands of residential and light commercial furnaces, boilers, as well as heat pumps. Our fully stocked warehouse means we carry most common parts. In the dead of winter, having the part in stock saves you money and headaches. If by the rare chance we would need to order your part, we offer free courtesy heaters to keep your home from freezing until we get your heat back on. Your comfort and safety is our top priority!

Furnace Tune-Ups

We all know how rough our Wisconsin winters are. Tune-ups are important to have performed annually, while the time of the year is not critical, the fact that they are done by qualified technicians is important. If you're curious of what we perform on our tune-ups you can see our list here. Our tune-ups take about 45-60 minutes per gas equipment, and 60-90 for oil equipment.
