Turn to the Experts

At Gross Heating & Air Conditioning, the customer always comes first. We sell the finest equipment available in the industry–Carrier furnaces, central air conditioning and indoor air quality products. We back that equipment with NATE-certified technicians, modern facilities, a large and fully stocked warehouse, and a fleet of service and installation vehicles.

100% Customer Satisfaction Guarantee


We service all brands, but we’re proud to recommend Carrier, a global leader in year-round indoor comfort. Gross Heating has been acknowledged as a top Carrier Factory Authorized Dealer, meeting the industry’s most rigid training and service standards. We offer all of our customers a 100% Customer Satisfaction Guarantee! If, for any reason, you are dissatisfied with your Carrier equipment within one year of the installation date, we will repair, replace or refund your money.

In the heating and air conditioning business, where consumers put their trust is vital. Here’s what Wayne Larrivee, American sportscaster and play-by-play voice of the Packers Radio Network has to say about us. “How did your air conditioner stand up to last summer’s heat? When it was time to upgrade my A/C, I turned to the experts at Gross Heating. That’s because locally owned Gross Heating has been keeping folks comfortable since 1925. I knew I could trust them and their Carrier line of quality products. As a result, my home was comfortable all summer long and I saved on energy bills. Choose Gross Heating for your comfort system like I did. They’re the MVP on my team!”
