When I was shopping for a new furnace, I knew I didn’t just want heat for this winter—I wanted a system that would keep my family warm for the next couple of decades. That’s why the warranty and lifespan were two of the biggest factors in my decision to go with a Goodman 80 AFUE Ultra-Low NOx furnace.
👉 In this guide, I’ll walk you through exactly what Goodman’s warranty covers, what it doesn’t, and how long you can realistically expect your 80 AFUE furnace to last with proper care.
📜 Goodman Warranty Basics
Goodman has built a reputation as one of the best warranty providers in the HVAC industry.
Standard Coverage
-
Heat Exchanger: Lifetime limited warranty (for original owner, as long as you live in the home).
-
Parts: 10-year limited parts warranty (with registration).
-
Cabinet & internal components: Covered under the parts warranty.
Registration Requirement
-
To get the full 10-year parts warranty, you must register your furnace within 60 days of installation.
-
If you don’t register, the parts warranty drops to 5 years.
👉 Tony’s Take:
“The lifetime heat exchanger warranty was what sold me. That’s the most expensive part of the furnace, and Goodman backs it for as long as I own my home.”

⚠️ What’s Not Covered
Like any warranty, Goodman’s coverage has limitations.
-
Labor costs: Standard warranty only covers parts, not the technician’s time.
-
Improper installation: If it’s not installed by a licensed professional, warranty may be voided.
-
Lack of maintenance: Skipping regular filter changes or annual tune-ups can disqualify claims.
-
DIY repairs: Attempting repairs yourself may void coverage.
👉 Tony’s Take:
“I always remind homeowners—keep your receipts for maintenance. If something goes wrong, Goodman may ask for proof you kept up with service.”
Consumer Reports notes many HVAC warranties exclude labor.
🧰 Optional Extended Warranties
If you want labor coverage, Goodman offers extended service agreements through its dealer network.
Benefits
-
Covers parts and labor for repairs.
-
Reduces out-of-pocket expenses for major breakdowns.
-
Peace of mind during the first 10 years of ownership.
Cost
-
Typically $300–$700, depending on dealer and plan.
-
Can save thousands if a blower motor or control board fails.
👉 Tony’s Take:
“I didn’t buy the extended warranty, but I can see why some people do. If a blower motor goes out, you’ll be glad you have labor covered.”
Furnace repair costs—a blower motor replacement alone can run $600–$1,200.
⏳ Furnace Lifespan Expectations
A Goodman 80 AFUE furnace, like mine, is built to last 15–20 years with proper care.
Average Lifespan
-
Well-maintained: 18–20 years.
-
Poorly maintained: 8–12 years.
Factors That Affect Lifespan
-
Filter changes: Dirty filters strain the blower motor.
-
Annual tune-ups: Catch problems early before they become major repairs.
-
Installation quality: A poorly sized or installed furnace won’t last as long.
-
Climate: Furnaces in harsh winters run harder and may wear out faster.
👉 Tony’s Take:
“I expect my Goodman to last 18–20 years. But only because I stay on top of maintenance. Skip the basics, and you’ll be buying a new furnace way sooner.”
Energy Star notes average furnace lifespans of 15–30 years.
🔍 Signs Your Furnace Is Nearing End-of-Life
Even with good maintenance, no furnace lasts forever.
Warning Signs
-
Rising repair bills: More frequent service calls and part replacements.
-
Uneven heating: Some rooms feel warm, others stay cold.
-
Higher energy bills: Efficiency drops as parts wear out.
-
Strange noises: Grinding, rattling, or booming sounds.
-
Cracks in heat exchanger: Dangerous—can release carbon monoxide.
👉 Tony’s Take:
“The rule of thumb is simple: if repairs cost more than a third of a new furnace, it’s time to replace.”
