Our story
Naugle started in Tecumseh in 1980 with one truck, one phone line, and a promise: do the work right, charge a fair price, treat people the way we'd want to be treated. Forty-five years and a few generations later, we're still here — same family, same shop, just more services and more people you'll recognize on the truck.
What started as a heating and cooling business has grown into a full home services company. Today, our licensed technicians and tradespeople handle heating, cooling, plumbing, and electrical work — all under one roof. One call, one company, one team that already knows your home and how it's wired.

Community first
We're not a national chain — we're your neighbors. Our trucks are parked in Tecumseh, our kids went to school here, and we shop at the same grocery store you do. That changes how we run a business. Reputation is the only thing that matters in a town of <10,000 people, and we've spent four decades building ours one job at a time.
