High-efficiency furnace installation, done right

If your furnace is over 15 years old or you've had multiple repair visits in the last year, replacement usually makes more sense than another patch. Modern high-efficiency furnaces run up to 99% AFUE — meaning 99 cents of every heating dollar actually heats your home, compared to roughly 80 cents on a typical 20-year-old system. The annual gas-bill savings add up fast in Michigan winters.

Every install starts with a free in-home sizing assessment — we measure your space, check your insulation, and look at airflow. The right-sized system runs quieter, lasts longer, and costs less to run (oversized furnaces short-cycle, leave the house clammy, and wear out faster). We walk you through good/better/best equipment options and leave you with a written quote on the spot. No high-pressure close, no "today only" pricing.

Heat pumps & hybrid systems — the smartest heat for Michigan

For Michigan's climate, a Lennox hybrid heat system (cold-climate heat pump + backup gas furnace) is often the most efficient option a homeowner can install. The heat pump handles 80% of the year at electricity-only cost; the gas furnace kicks in only on the coldest snaps. Average Lenawee homeowners report 30-50% lower heating bills after switching. The federal heat pump tax credit (25C) applies to qualifying installs, and Consumers Energy and DTE both offer rebates that stack on top — we handle the paperwork. Ask about financing options at the in-home estimate.

Our process

How a Naugle furnace install actually works

No mystery, no surprises. Same process whether you're replacing a 1995 single-stage clunker or speccing a hybrid heat system for a new build.

  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.

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 maintenance — catch problems before they're emergencies

Annual furnace tune-ups extend equipment life by 30-40%, keep your manufacturer warranty in force, and trim winter utility bills 5-15% by maintaining design-spec airflow and combustion efficiency. Our ClimateGuard Premier Service Plan bundles your fall furnace tune-up and spring AC tune-up at a discounted annual rate, plus member-only perks: priority scheduling during peak season, no after-hours overtime charges, 15% off any repairs, and free seasonal safety inspections. About 1 in 4 winter furnace failures we see are issues that an annual tune-up would have caught.

About rebates, tax credits, and financing on new heating equipment

There's real money on the table for high-efficiency heating right now and we make sure you don't leave it. The federal Energy Efficient Home Improvement Credit (25C) covers qualifying heat pumps and high-efficiency furnaces. Consumers Energy and DTE both offer rebates that stack on top of the federal credit. For income-qualified Michigan households, the HEAR program adds additional rebate dollars for heat pump installations. We confirm exactly what you qualify for at the in-home estimate and handle every form.

Financing is straightforward: 0% APR options on qualifying installs (typically 12-24 months), plus standard term loans for larger projects spread over 5-10 years. Most homeowners get approved in minutes during the in-home estimate. We'll show you the all-in monthly payment alongside the cash price so you can decide what works.

FAQ

Heating questions, answered

Most modern gas furnaces last 15-20 years with annual maintenance. Once a furnace passes 12-15, repair costs typically start to outweigh the energy savings a new high-efficiency unit would deliver. Michigan winters are hard on equipment — short-cycling and constant runtime add up. We'll give you a straight read during a free in-home assessment.

Pay over time, not all at once

0% APR financing on qualifying installations

  • Decision at the estimate. We bring the lender right to your kitchen table. Approval is typically a few minutes.

Financing through third-party lenders. Terms and approval depend on credit qualification, loan product, and equipment.
