Naugle started in Tecumseh in 1980 with one truck and a promise: do the work right, charge a fair price, treat people the way we'd want to be treated. Four decades later, we're still here — same shop on S Adrian St, expanded trades, and a team that lives in the communities we serve.
Today we handle heating, cooling, plumbing, and electrical under one roof. One call, one company, one team that already knows your home — and shows up when we say we will.

Why Naugle
Our promises to you
How we work — written down so you can hold us to it.
Written, flat-rate pricing
You see the all-in price before any work begins. No time-and-materials surprises, no overtime gotchas, no "we'll see when we get into it."
Right-sized for your home
Every install starts with a full in-home sizing assessment. We measure your space and check insulation so the equipment fits your house — not whatever the last guy installed.
A real person, every call
Call 517-423-3121 and a real person picks up during business hours (M–F 8 AM – 5 PM) — no phone tree, no offshore call center. After-hours heating & cooling emergencies roll to an on-call HVAC rotation for Lenawee County.
Multiple brands, multiple price tiers
Three written equipment options at three price points on every install. Different families have different budgets — you pick what fits.
Permits handled, rebate docs in your hands
We pull every required permit and coordinate inspections. For Consumers Energy or DTE utility rebates you qualify for, we hand you the equipment documentation you'll need to submit.
Same shop, same street, since 1980
Working out of the same building on S Adrian St in Tecumseh for 45 years. Locally operated, with technicians who live in the communities we serve.

At your door, on time
Free in-home estimates
Every install starts with a free in-home assessment — we measure your space, walk you through the options, and put the quote in writing on the spot.
“These folks are very friendly and professional. They responded quickly to my request for a quote. The installation was completed the very next day!”
“I just had a floor unit mini-split installed and I'm very impressed with the Naugle team's quality of work and their dedication to getting it right for the customer.”
“A very professional company. Did a complete install for me, and we are happy with the price and their work. Thanks again.”
“What an AMAZING company! I know we will be using them as needed for years to come. We had our central air replaced today. I can't say enough about this company!”
“Was referred to Naugle by a friend and they are fantastic!”
“Called at 7 AM with no heat — they had a tech here by 9:30 and we were warm again before noon. Fair price, no upsell. Exactly what you want.”
Where We Work
Proudly serving Lenawee County & southeast Michigan
Same-day service throughout our coverage area. If you're inside 45 minutes of Tecumseh, we're probably already working in your neighborhood.
Pay over time, not all at once
0% APR financing on qualifying installations
A new HVAC system, generator, panel upgrade, or whole-home repipe shouldn't strain the family budget. We offer 0% APR financing on qualifying installs (typically 12-24 months), plus longer-term loans for larger projects. Most homeowners get approved in minutes during the in-home estimate.
- Soft credit check (no impact on your score)
- Decision in minutes, not days
- Monthly payment shown alongside cash price
- No prepayment penalties
How financing fits with your install
- Same equipment options. Financing doesn't change what we install or how — only how you pay for it.
- Multiple plan lengths. Short-term 0% APR promos through longer-term loans, so the payment fits the household budget.
- Decision at the estimate. We bring the lender right to your kitchen table. Approval is typically a few minutes.
- Stack with utility rebates. Financing works alongside any Consumers Energy or DTE rebate you qualify for — we hand you the equipment documentation you'll need to submit.
Financing through third-party lenders. Terms and approval depend on credit qualification, loan product, and equipment.
