Pat's Heating & Air Conditioning

Pat's Heating & Air Conditioning has operated from Oconomowoc since 1989, building a 37-year track record that reflects deep roots in Wisconsin's Lake Country. The company holds a 5.0-star rating across 1,803 Google reviews, a volume that indicates both consistency and community trust. Beyond Oconomowoc, technicians service Delafield, Hartland, Waukesha, Pewaukee, Brookfield, and surrounding communities including Sussex, Ixonia, and Genesee. The family-owned operation provides 24/7 emergency availability, meaning a heating failure on Christmas morning or a mid-August heat wave receives the same rapid response as a scheduled tune-up.

What distinguishes Pat's is the breadth of capabilities under one roof. The company operates as a Lennox dealer and installs Kohler whole-home generators, handling both the HVAC and electrical dimensions of modern home comfort. Indoor air quality offerings include air filtration, smart thermostats, and humidifier-dehumidifier systems. For commercial properties, they install Variable Refrigerant Flow (VRF) systems, a specialized zoning technology that serves multi-tenant buildings. Their maintenance agreements bundle annual inspections with discounted repair rates, giving homeowners a structured approach to equipment longevity rather than reactive calls when systems fail.

Customer reviews name specific technicians handling identifiable scenarios. Sean and a crewmate recently installed a garage heater for Todd Cochran, arriving with a competitive estimate that beat three competitors. For Rick Schadt, the team performed a 200-amp electrical service upgrade alongside ceiling fan and bathroom exhaust installations across two visits, a scope that required coordination between their electrical and HVAC divisions. Paul M handles annual furnace maintenance for existing maintenance-plan clients, texting ahead before arrival. Luke, their Kohler-certified technician, performs generator annual maintenance, addressing a specialty that requires manufacturer certification most general HVAC contractors lack.
