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
Business hours or 3 a.m. — call 517-423-3121 and a real person picks up. No phone tree, no offshore call center. After-hours emergency rotation covers 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 & rebates, handled
We pull every required permit, coordinate inspections, and file the federal tax credit and utility rebate paperwork. You don't chase forms.
Same family, same shop, since 1980
Three generations of Naugles working out of the same building on S Adrian St in Tecumseh. The owner's name is on the truck for a reason.
Current offers & incentives
Save more on your install
Federal tax credits, utility rebates, and 0% financing — we make sure you don't leave money on the table.
Heat Pump Energy Credit
Install a qualifying heat pump and claim the federal Energy Efficient Home Improvement Credit (25C) on your taxes. Stackable with Consumers Energy and DTE rebates — we file the rebate paperwork for you.

Financing on Qualifying Installs
12-24 month 0% APR plans available on most new furnace, AC, heat pump, water heater, panel upgrade, and generator installations.
Subject to credit approval. Standard term loans available for larger projects.
Right-Sized for Your Home
Every in-home estimate includes a full sizing assessment — we measure your space, check insulation, and look at airflow — so your new equipment fits your actual home, not whatever was installed before.

“A very professional company. Did a complete install for me, and we are happy with the price and their work. Thanks again.”

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 rebates. Financing works alongside any utility rebate or federal tax credit you qualify for — we file the paperwork.
Financing through third-party lenders. Terms and approval depend on credit qualification, loan product, and equipment.
