Gas Furnace Replacement FAQ

Ads sometimes show furnaces as low as $2,495, but that typically means very small homes or DIY installs without duct changes or permits.

For a licensed, professional installation in Macomb County, the realistic range is $3,900–$10,000. Final cost depends on AFUE rating, staging (single/two-stage/modulating), furnace blower type, duct condition, and installation complexity.

AFUE = Annual Fuel Utilization Efficiency.
  • 80 AFUE: 80% of fuel becomes heat, 20% lost.
  • 96 AFUE: 96% efficient, only 4% lost.
  • 99 AFUE: Top efficiency, nearly every dollar goes into usable heat.

A PSC blower is single-speed (fully on or off). Lower upfront cost but higher energy use and uneven comfort.

An ECM blower is variable-speed, adjusting smoothly for quieter, steadier airflow with less electricity.

In Michigan:
  • PSC: ≈ 840 kWh per winter season (~$175/year at June 2025 rates).
  • ECM: ≈ 270 kWh per season (~$56/year).
That’s about $120/year saved, or ≈ $3,250 over 20 years with Michigan’s 3.19% average annual electricity escalation.

  • Single-stage: One flame level. Cheapest upfront, least efficient, uneven comfort.
  • Two-stage: Low flame most of the time, high flame only in extreme cold. Quieter, more efficient.
  • Modulating: Adjusts in small increments with an ECM blower. Quietest, most efficient, steadiest comfort.

With yearly maintenance, a furnace can last up to 20 years. Without maintenance, the lifespan often drops to 10 years or less.

Yes, when viewed over the furnace’s full 20-year life:
  • Gas savings: A 99% AFUE furnace uses ~19.2% less gas than 80%. With $800 Year-1 usage:
    • 0% escalation: ≈ $3,072 saved in 20 years
    • 2% escalation: ≈ $3,744 saved
    • 4% escalation: ≈ $4,464 saved
  • Electricity savings: ECM vs PSC saves ≈ $3,256 in 20 years.
Combined savings: ≈ $6,300–$7,700.

Replacement is usually the better option when:
  • The furnace is 20 years old with maintenance, or 10 years or less without
  • The heat exchanger is cracked, or it fails a safety test
  • Repair costs keep rising year after year
  • Energy bills climb despite regular service
  • Heating is uneven, the unit short-cycles, or it becomes noisy

Most high-efficiency furnaces from top brands, such as Rheem and Lennox, include 5- to 10-year parts coverage, and many offer 20-year or lifetime warranties on heat exchangers (depending on the model and registration). Always check the manufacturer’s specific warranty for your unit.

Not always. Many Macomb County homes only need small duct sealing or return upgrades. We test airflow and static pressure to confirm.

Yes. Programs change often, but manufacturer rebates, utility company rebates, state incentives, and federal tax credits are usually available. Charter Home Comfort tracks these and makes sure you have all the information needed to claim the maximum rebates at installation time.

Yes. Financing options are available (with approved credit) with flexible monthly payments.

Most replacements are completed in one day. Jobs with duct modifications or code updates may require additional time.
