Quick answer

Naugle repairs furnaces across Tecumseh and southeast Michigan — locally operated since 1980 and rated 4.8 stars on Google. You get an upfront flat-rate price before any repair begins, and we service all major brands. A diagnostic fee applies and is credited toward the repair if you proceed. After-hours emergency service is available for heating and cooling. Call or text 517-423-3121.

Signs your furnace needs repair

No heat, or not enough heat. A furnace that turns on and off every few minutes. Banging, squealing, or grinding from the furnace. A blower that runs but only pushes cold air. A burner or pilot that won't stay lit. A thermostat that can't keep the house at the temperature you set.

If you smell gas, leave the house and call your gas utility from outside first. For everything else, call or text 517-423-3121 — our office is open Monday through Friday, 8 AM to 4:30 PM, and after-hours emergency service is available for heating and cooling.

Request Furnace Repair

Upfront, flat-rate pricing — before any work begins

Before we start a repair, you get an upfront flat-rate price, so you know the cost before you say yes. A diagnostic fee applies to find the problem, and it's credited toward the repair if you proceed.

We service all major furnace brands, so it doesn't matter who installed yours.

Repair or replace? An honest answer

It's case by case, but age matters. Around 15 years old is early for major repairs. After 20 years, we recommend replacement over repair. After 25 years, we recommend replacing rather than repairing — and we can't warranty repairs on a furnace that old.

If replacement makes more sense, see our furnace replacement page: Lennox, Carrier and Payne furnaces, and a standard replacement takes one day.

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 – 4:30 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.

Our guarantee

Warranty on a new furnace

When replacement makes more sense than repair, a new furnace from Naugle comes with our standard warranty (subject to change by unit):

  • 10 years on parts
  • 20 years on the heat exchanger
  • 18 months on labor
  • Repairs on furnaces older than 25 years can't be warrantied — at that age we recommend replacing
