❄️ That Moment When the Furnace Hesitates …

It’s the first cold night of the season. You hear the burner light, then — click … silence. Blanket over your shoulders, you ask the question every homeowner eventually faces:

Should I repair or replace my furnace?

In this playbook, I’ll help you recognize when a repair still makes sense, when replacement is smarter, and how the newest Goodman® furnaces can deliver quieter, more efficient comfort (and lower bills).

🔧 1. Five Clear Signs It’s Time to Replace

Age 10–15 Years + — Most furnaces hit their efficient lifespan around the decade mark.
Frequent Repairs — Two or more major fixes in two winters usually means diminishing returns.
Rising Energy Bills — An aging 80 % AFUE unit wastes 20 ¢ of every fuel dollar.
Uneven Comfort — Cold rooms and short cycles suggest heat-exchanger or blower wear.
Safety Flags — Rust, cracks, or CO alarms mean it’s time to stop patching and start planning.

🧰 Pro Insight: “If your repair costs hit about 30 % of a replacement quote — and comfort’s slipping — a new Goodman furnace usually pays itself back in energy savings.” — Melissa Haws

🪛 2. When a Repair Still Makes Sense

Situation	Smart Move	Typical Cost Range
Newer (< 10 yrs), minor part (ignitor, flame sensor)	Repair	$150 – $400
Blower motor failure with warranty coverage	Repair	$600 – $1,200
Cracked heat exchanger or safety shutdown	Replace	$3,000 – $7,000
Multiple repairs in 2 years	Replace	—

Small fixes can buy you another season — but stacking bills on an aging system rarely adds up.

🧰 Pro Insight: “One more ‘quick’ repair often costs the same as upgrading to a higher-AFUE system with financing.”

⚙️ 3. Efficiency and ROI Math

Replacing an 80 % AFUE furnace with a 96 % model saves roughly $200 – $400 per year in fuel, depending on gas rates. Over 10 years, that’s $2 000 – $4 000 back in your pocket — plus steadier heat and quieter starts.

AFUE = Annual Fuel Utilization Efficiency — how much of your fuel becomes usable heat.
The closer to 100 %, the less you waste.

🛡️ 4. Safety & Peace of Mind

Carbon-monoxide leaks, shorted wiring, and flue deterioration can turn a “wait-and-see” into a crisis. New sealed-combustion designs draw outside air and exhaust through PVC venting, protecting indoor air quality while quietly running at higher efficiency.

🧰 Pro Insight: “If you own a CO detector because of your furnace, it’s already time to price a replacement.”
