Quick answer

Naugle handles AC repair, central air installation, and ductless mini-splits across Lenawee County and southeast Michigan — serving the area since 1980. Most emergency AC calls receive a same-day technician during summer. Free in-home estimates on every install, with financing available through Wisetack. Lennox Premier Dealer and Carrier Factory Authorized — same two brands for central AC and mini-split installs. Call or text 517-423-3121.

Same-day AC repair when summer turns serious

When your AC quits in July, you don't have a week to wait. Our service trucks stock the parts that fail most often — capacitors, contactors, fan motors, thermostats, control boards — so most repairs are done same-visit. We service every major brand. Call 517-423-3121.

High-SEER central AC installation, sized right

Oversized central air conditioners leave the house clammy. Undersized ones run constantly without ever getting cool. Both wear out faster than systems sized correctly. We measure your home and check your existing setup on every install estimate, then give you three equipment options in writing.

Mini-splits — comfort for the rooms central air doesn't reach

Finished attic that's always 10° too warm? Sunroom you can't enjoy in July? Garage apartment without ductwork? A ductless mini-split solves it without tearing into your home. Multi-zone systems can serve a whole home with 2-5 indoor heads off one outdoor unit.

Our process

How a Naugle AC install actually works

Same playbook as heating: assess, quote in writing, schedule, install clean, walk you through.

  1. 1

    Free in-home assessment

    A senior tech (not a salesperson) walks your home, measures your space, checks insulation, looks at your existing ductwork, and calculates what your home actually needs. Takes 45-60 minutes.

  2. 2

    Written quote with three options

    We give you good/better/best equipment options in writing — not a verbal handshake — with itemized labor, materials, permits, and equipment. Side-by-side so you can see what each tier actually buys you.

  3. 3

    Schedule the install (typically within 1-2 weeks)

    Once you pick an option, we schedule the install. Standard furnace swap-outs take one day; full system or conversion jobs may run 1.5-2 days. We give you a 2-hour arrival window, not a vague 'morning' or 'afternoon.'

  4. 4

    Install day — clean, careful, complete

    Drop cloths over your floors, shoe covers on, old equipment hauled away. We pull the permit, run the new gas/venting/electrical as needed, and don't leave until the system is running, calibrated, and labeled.

  5. 5

    Walkthrough, rebate paperwork, and warranty registration

    Before we leave we walk you through your new thermostat, show you how to change filters, register your equipment warranty, and start the rebate paperwork. You get a job folder with everything you'll need for the next 10 years.

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

What our warranty actually covers

Manufacturer warranties on installed equipment are passed through directly (typically 10 years parts on heat exchangers, 10 years on most components, 1 year on installation labor). We also back our own work:

  • 1-year labor warranty on every install — no asterisks
  • 10-year parts warranty on equipment we install (manufacturer standard)
  • Heat exchanger limited lifetime warranty on most Lennox & Carrier furnaces
  • Equipment warranty registration handled by us at install — you don't lose coverage to a missed deadline
  • ClimateGuard Premier members get extended labor coverage on annual-maintained equipment

ClimateGuard spring AC tune-ups

A 30-minute spring tune-up catches the things that cause July breakdowns: weak capacitors, low refrigerant from slow leaks, dirty condenser coils that cause the system to overheat. ClimateGuard Premier members get both spring AC and fall furnace tune-ups bundled at a discounted annual rate.

FAQ

Cooling questions, answered

Central air conditioners typically last 12-17 years. Once an AC passes 10 years — and especially if it's an older R-22 (Freon) system — repair costs climb fast and you're paying significantly more in monthly utility bills than a modern high-SEER replacement would cost. R-22 has also been phased out by the EPA, so refrigerant charges on older units are expensive when available at all.

Pay over time, not all at once

  • Ask at your estimate. Your estimate includes a link to apply, or ask your technician or our office.
  • 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.
