Southport Home Services

What Southport Home Services does

Southport Home Services, operating as Southport Engineered Systems, LLC and doing business as Southport Plumbing, Heating & Cooling, is a Wisconsin-based residential and commercial home services company founded in 2005 and headquartered in Caledonia, WI. The company delivers an integrated bundle of HVAC, plumbing, indoor air quality, and specialty services through NATE-certified technicians dispatched in fully stocked service vehicles, with 24/7 emergency availability across Southeast, South-central, and North-central Wisconsin from three offices (Caledonia, Madison, Wausau) serving roughly sixteen plus municipalities.

The core product surface covers air conditioning (installation, maintenance, repair, ductless mini-splits), heating (furnaces, boilers, heat pumps, radiant), plumbing (drain cleaning, water heaters, water treatment, gas lines, hydrojetting, remodels), indoor air quality (duct cleaning/sealing, HEPA, UV, dehumidification), and advanced HVAC work (zoning, ERV, VRF, thermostats). A commercial vertical adds commercial HVAC, commercial plumbing, fire protection, and wholesale ductwork. The technical backbone is field-service oriented: a route-dispatched workforce, fully stocked mobile warehouses enabling one-visit repairs, an online scheduling interface, and a 140+ article educational blog used for organic acquisition.

The business model combines on-demand professional services (one-time repair calls, 24/7 emergency labor plus parts), equipment installation (HVAC, water heaters, plumbing fixtures — hardware-plus-labor revenue), a recurring Shield Maintenance Plan (three annual visits, priority scheduling, 15% discount), and a commercial services line. Customer acquisition runs through Google Business Profile, organic content/SEO, direct phone, online scheduling, and customer referral and yard-sign programs. The company is family-owned, privately held, with no disclosed institutional investment or parent entity.
