Horsch & Miller, Inc.

Horsch & Miller, Inc. has served Slinger and the greater Washington County area since 1954, building a legacy as a family-owned heating, cooling, and plumbing contractor. With 332 customer reviews earning a 4.9-star average, the company employs a team of fully-trained technicians who handle residential and light commercial projects. The business operates Monday through Friday from 7 AM to 4:30 PM and maintains 24/7 emergency availability, with an owner or master plumber returning emergency calls within 15 minutes or the service call is free.

The contractor distinguishes itself through a Kohler Authorized Showroom where customers can select fixtures with trained consultants, and through partnerships with major brands including Armstrong Air, Concord Air, Napoleon Air furnaces, LG Home Comfort systems, Crown Boilers, and NTI boilers. Their service menu extends beyond traditional HVAC to include geothermal heating systems, heat recovery ventilation, water treatment, well pumps, and sump pumps, a breadth unusual among area contractors. This multi-trade capability allows the company to handle complex remodels and new construction projects that require coordination across heating, cooling, and plumbing systems.

Customer reviews name specific technicians who delivered exceptional service. Brad arrived 20 minutes ahead of his scheduled time to fix a leaking bathtub faucet, listening carefully to the homeowner's preferences for bathroom upgrades and leaving no mess behind. For a major basement bathroom project, Ryan provided a reasonable quote within two days, while Brad and Travis completed the work in two and a half days, using plastic sheeting and floor mats to contain dust and debris. Another reviewer praised Dan and Brian for installing a water softener and indirect water heater, taking time to explain maintenance requirements.
