Diversifying over the past 120 years, from a blacksmith shop to a full-service supplier of home comfort products Wulf Brothers has grown in response to expanding customer satisfaction. Wulf Brothers began as a blacksmith shop in the 1870 s and over the years went through many changes and transitions. In 1982 Wulf Brothers Inc. expanded into heating and air conditioning systems for homes and businesses. As the main part of our business today we have two licensed HVAC Design Engineers on staff and have over 65 employees serving our customers. Our staff and crews are continually trained in the latest products and features for your home or business. Customers have trusted Wulf Brothers to professionally design, install and service their comfort system for many years. As the HVAC Division grew, Wulf Brothers diversified into helping customers find solutions when experiencing electrical or fuel outages (Low Temperature Alert Systems). This was the beginning of our security division Home Systems Integration. In 1998 Wulf Brothers relocated to the current Sturgeon Bay location along the highway and expanded product offering to include Hot Spring Spas and more of a variety of fireplaces and stoves.
