Haak Heating Inc

There are a lot of companies that do what we do—repair, maintain, and install HVAC equipment. But there are few with as many longstanding, loyal customers! With over 40 years in the business, we’re glad to be the cooling company so many residents in Green Bay, De Pere and Ashwaubenon know trust. Our philosophy is simple: we treat our customers the way we'd like to be treated. Before starting work, we educate you as to your options and potential costs of your ac repair or air conditioner replacement.
