🏠 Introduction: Three Brands, One Big Decision
When Samantha Reyes decided it was time to replace her aging gas furnace, she thought choosing a new one would be simple. But as she explored her options, three brands kept appearing in every conversation — Goodman, Amana, and Rheem.
“I quickly realized they all made R-32 furnaces, but each brand had its own strengths,” Samantha explains. “Some were more affordable, others had better warranties. I wanted to know which one actually gave me the best value for my home.”
In 2025, more homeowners are asking the same question. As the HVAC industry transitions to R-32 refrigerant and tighter SEER2 and AFUE standards, Goodman, Amana, and Rheem have each rolled out advanced, low-emission furnace models designed for efficiency and compliance.
This in-depth guide compares these three leading manufacturers based on price, performance, durability, warranty coverage, and rebates — all from Samantha’s perspective as a savvy homeowner looking for both comfort and long-term savings.
🌿 1. The R-32 Advantage: Why This Comparison Matters
Before comparing brands, it’s worth understanding why the refrigerant inside your furnace system matters.
🔬 What Makes R-32 Different:
-
68% lower Global Warming Potential (GWP) than R-410A.
-
Higher heat transfer efficiency, meaning faster, more even heating.
-
Uses 20–30% less refrigerant volume per system.
-
Zero ozone depletion potential.
-
Complies with 2025 EPA AIM Act phase-down standards.
According to Daikin Global, R-32 is the world’s most widely adopted next-generation refrigerant, used in over 150 countries for its performance and low environmental impact.
🌎 Why It Matters to You:
-
Future-proof against refrigerant bans and penalties.
-
Lower operational costs due to higher efficiency.
-
May qualify for rebates or tax credits (as covered in the previous article).
“It’s nice knowing my furnace won’t be outdated by new EPA rules,” Samantha says. “That peace of mind made R-32 systems a must-have for me.”
💸 2. Price Comparison: Upfront Equipment & Installation Costs
For most homeowners, cost is the first factor when comparing brands. Let’s look at how Goodman, Amana, and Rheem stack up in 2025.
| Brand | Typical Price Range (Installed) | Efficiency (AFUE) | Value Summary |
|---|---|---|---|
| Goodman | $6,500–$8,000 | 95%+ | Budget-friendly, reliable, easy to service |
| Amana | $7,000–$9,000 | 96–97% | Premium comfort and warranty |
| Rheem | $7,200–$9,200 | 95–96% | Smart controls and balanced design |
🧾 What Impacts Final Price:
-
Furnace BTU capacity (60K–100K).
-
Whether it’s a single-stage, two-stage, or modulating system.
-
Labor costs and ductwork complexity.
-
Optional add-ons (smart thermostats, humidifiers, zoning).
“Goodman was the most affordable upfront,” Samantha notes. “But I had to weigh that against Amana’s lifetime warranty and Rheem’s quiet operation.”
🔋 3. Efficiency & Performance: Heating Smarter, Not Harder
When comparing efficiency, AFUE (Annual Fuel Utilization Efficiency) is the key metric — the higher, the better.
| Brand | AFUE Rating | SEER2 (if hybrid) | Efficiency Benefit vs. R-410A |
|---|---|---|---|
| Goodman | 95% | 15.2 | 10–12% higher |
| Amana | 96–97% | 15.5 | 12–14% higher |
| Rheem | 95–96% | 15.3 | 11–13% higher |
All three brands exceed ENERGY STAR® requirements, but Amana slightly leads in both heating performance and hybrid readiness.
🔧 Real-World Efficiency Insights:
-
Goodman: Ideal for moderate climates and steady winter heating.
-
Amana: Best for variable climates — higher efficiency and adaptive output.
-
Rheem: Balanced across temperature ranges, thanks to modulating burners.

“I liked that Amana adjusts to my home’s needs automatically,” Samantha says. “It saves gas without sacrificing warmth.”
🔈 4. Noise Levels & Comfort Design
Noise is one of the most overlooked — yet most noticeable — aspects of furnace comfort.
| Brand | Average Noise Level | Key Comfort Features |
|---|---|---|
| Goodman | 55–60 dB | Two-stage burner, insulated cabinet |
| Amana | 50–55 dB | ComfortBridge™ technology, quiet variable fan |
| Rheem | 52–57 dB | EcoNet™ smart control system, modulating burner |
🧠 Comfort Enhancements:
-
Goodman offers solid basic comfort at an affordable price.
-
Amana integrates sensors that adapt output for room-by-room consistency.
-
Rheem connects to smart home systems, allowing app-based control and diagnostics.
“When my Amana runs, I can barely hear it,” Samantha notes. “It’s like the system knows exactly how to keep every room even.”
🧱 5. Build Quality & Durability
Each brand’s engineering philosophy is slightly different — and it shows in the build materials and design features.
🛠️ Construction Overview:
| Brand | Heat Exchanger | Cabinet | Distinct Feature |
|---|---|---|---|
| Goodman | Aluminized-steel tubular | Heavy-gauge steel | Simple, rugged design |
| Amana | Stainless-steel primary & secondary | Sealed cabinet | Premium corrosion protection |
| Rheem | Aluminized-steel modulating | Reinforced casing | Enhanced airflow and noise dampening |
Expected lifespan: 15–20 years, with Amana and Rheem edging slightly higher due to advanced corrosion resistance.

“I liked that Amana uses stainless steel,” Samantha says. “It feels built to last.”
🧾 6. Warranty & Protection Plans
Warranty coverage can make a major difference in long-term value.
| Brand | Heat Exchanger Warranty | Parts Warranty | Replacement Guarantee |
|---|---|---|---|
| Goodman | Lifetime | 10 years | 10-year replacement |
| Amana | Lifetime | 10 years | Lifetime replacement |
| Rheem | 20 years | 10 years | Optional extended plan |
Amana’s lifetime unit replacement warranty is unmatched — if the heat exchanger fails, they replace the entire furnace. Goodman offers strong coverage for the price, while Rheem’s plans vary depending on distributor and installer.
“The lifetime replacement promise sealed the deal for me,” Samantha says. “I knew I’d never have to buy another furnace.”
🧹 7. Maintenance & Serviceability
Routine maintenance is crucial for preserving your furnace’s efficiency.
🧰 Annual Maintenance Overview:
| Brand | Maintenance Difficulty | Typical Annual Cost | Notes |
|---|---|---|---|
| Goodman | Easy | $150–$200 | Simple design, low-cost parts |
| Amana | Moderate | $180–$250 | Smart diagnostics reduce service time |
| Rheem | Moderate | $200–$300 | Proprietary controls require certified techs |
“My technician said Goodman is the easiest to work on, but Amana’s diagnostics made annual checkups quicker,” Samantha explains.
🌍 8. Environmental Impact
All three brands deliver major environmental advantages over older R-410A models.
| Brand | GWP Rating | CO₂ Emission Reduction | Compliance |
|---|---|---|---|
| Goodman | 675 | 65% lower | ✅ EPA AIM Act |
| Amana | 675 | 68% lower | ✅ ENERGY STAR |
| Rheem | 675 | 66% lower | ✅ DOE 2025 standards |
R-32 furnaces also reduce total refrigerant use by up to 30%, helping homes lower their carbon footprint without sacrificing comfort.

“I liked that all three brands were environmentally responsible,” Samantha says. “But Amana’s hybrid-ready option really stood out.”
🧮 9. Lifetime Cost of Ownership
When calculating long-term value, it’s not just the purchase price — it’s efficiency, warranty, and maintenance combined.
| Brand | Installed Cost | Annual Energy | 15-Year Maintenance | Total Lifetime Cost |
|---|---|---|---|---|
| Goodman | $7,000 | $1,050 | $2,500 | $24,250 |
| Amana | $8,000 | $950 | $2,250 | $24,000 |
| Rheem | $8,200 | $970 | $2,400 | $24,550 |
Even though Amana has the highest initial cost, its lower energy consumption and unmatched warranty give it the best long-term return on investment (ROI).
“Amana cost more upfront, but over 15 years it actually saves me money,” Samantha notes. “That made it a clear winner.”
💵 10. Rebates, Tax Credits & Incentives
In 2025, R-32 furnaces qualify for several energy-efficiency incentives.
Federal Tax Credit (25C)
