About Us


ASP (Previously Summit Mechanical Service) was founded in 2000 to provide plumbing, heating, ventilation, and air conditioning services primarily to residential customers in Duluth and surrounding areas. In 2001 the business increased its scope to include light commercial and multiple unit projects. ASP/Summit Mechanical has expanded to become one of the leaders in providing prompt and professional plumbing and heating services to both new and remodeling residential and commercial projects, specializing in custom radiant/in-floor heating systems and also forced air, ventilation, and air conditioning.

Many of our completed projects have been designed/built for upper-end, large, custom homes, working with architects, general contractors, and owners to provide reliable, quality, customized comfortable systems while always striving for the highest operating efficiencies and most reasonable costs. Our business growth has been largely due to our reputation and much-appreciated referrals from our customers. By keeping our operation streamlined and efficient, we continue to be a leader in HVAC in the Duluth/Superior area.

ASP installs plumbing, heating, ventilation and air conditioning services according to local and state codes, as well as the uniform plumbing codes (UPC) and the Minnesota energy codes. We, at all times, recognize specific local code requirements in order to deliver superior services to every project we provide service to.
