Hillestad Heating & Cooling Systems

Hillestad Heating & Cooling Systems has served Madison-area homeowners for over two decades, building a reputation for tackling challenging retrofit installations in the city's vintage and historic properties. With 41 verified customer reviews averaging 4.5 stars, the contractor employs a team of licensed technicians who handle everything from emergency furnace replacements to complete system installations. The company operates primarily in Madison and surrounding Dane County communities, including Fitchburg, Middleton, and Verona, responding to both scheduled maintenance calls and same-day emergencies.

What distinguishes Hillestad from competitors is their willingness and ability to solve unconventional installation challenges that send other contractors looking for alternatives. Multiple reviewers noted the company proposed more logical solutions than larger competitors for homes with limited mechanical space or unusual ductwork configurations. The company also addresses indoor air quality concerns directly, with at least one customer specifically praising a custom oversized filter installation that resolved allergy issues, a detail that speaks to their problem-solving approach rather than cookie-cutter installations.

Customer stories from reviews reveal the day-to-day reality of working with this contractor. When a rental property furnace failed on a January cold snap, Hillestad replaced it the same day. Another customer described their 20-year-old central air system, retrofit into a 100-year-old house, as a tricky installation that other companies avoided, yet Hillestad successfully troubleshot and kept running for years before ultimately replacing it. Technician Jeff receives multiple shout-outs for his fair bidding process, flexibility with rescheduling, and straightforward communication about repair versus replacement decisions.
