When it’s time to replace or upgrade your HVAC system, the decision often comes down to brand. For large homes, a 5 Ton AC paired with a gas furnace is one of the most popular setups—and three names usually rise to the top: Goodman, Lennox, and Carrier.
I know how overwhelming it feels to compare these brands. When I was shopping for my own system, I had spreadsheets of costs, efficiency ratings, and warranty fine print. What I wanted was something simpler: a clear side-by-side comparison of which brand is best for what type of homeowner.
That’s what this guide is all about. Let’s walk through costs, efficiency, noise, warranties, and more, so you can make the smartest choice for your home.

🏡 Why Brand Matters for a 5 Ton System
A 5 Ton HVAC system isn’t a small purchase—it’s an investment in your home’s comfort for the next 15–20 years. Choosing the right brand means balancing:
-
Cost today (equipment + installation)
-
Cost tomorrow (energy bills + repairs)
-
Peace of mind (warranty + reliability)
Different brands position themselves differently:
-
Goodman is known for value and strong warranties.
-
Lennox is famous for premium efficiency.
-
Carrier often lands in the middle with reliable performance.
💵 Cost Comparison
Price is often the first question homeowners ask. Here’s what you can expect in 2025:
-
Goodman: $9,000–$12,000 installed
-
Carrier: $10,500–$14,000 installed
-
Lennox: $11,000–$15,000 installed
These ranges include equipment, installation, and typical accessories. Exact quotes depend on your contractor and location.
👉 Samantha’s tip: Always ask for an itemized quote. Some installers include extras like line sets or smart thermostats, while others add them later as surprise costs.
For price transparency, Goodman is usually the winner.
⚡ Efficiency (SEER2 & AFUE)
Efficiency matters because HVAC systems consume nearly 50% of a home’s energy use (DOE – Home Energy Guide ✔️).
Central AC Efficiency (SEER2)
-
Goodman: 14.3–16 SEER2 (baseline models); some higher options available.
-
Carrier: Up to 22 SEER2 with premium systems.
-
Lennox: Up to 24 SEER2—the highest among mainstream brands.
Furnace Efficiency (AFUE)
-
Goodman: 80–98% AFUE depending on model.
-
Carrier: Up to 98% AFUE.
-
Lennox: Up to 99% AFUE (flagship SLP99V).
👉 Translation:
-
Goodman meets minimums affordably.
-
Carrier balances efficiency with cost.
-
Lennox leads the pack but at a price premium.
🔊 Noise Levels
Noise is often overlooked until the system is installed. Here’s how the brands compare:
-
Goodman 5 Ton condenser: ~72–76 dB (like a vacuum).
-
Carrier 5 Ton condenser: ~65–72 dB (quieter models available).
-
Lennox 5 Ton condenser: as low as 59 dB on premium models (very quiet).
👉 Samantha’s tip: If your outdoor unit sits near a bedroom or patio, noise should be a deciding factor. A quieter system may be worth the investment.
🛡️ Warranties & Reliability
This is where Goodman shines.
-
Goodman: 10-year parts + lifetime compressor + lifetime heat exchanger (on select models).
-
Carrier: 10-year parts, limited lifetime heat exchanger.
-
Lennox: 10-year parts, 20-year heat exchanger (lifetime on some high-end models).
All three require product registration within 60–90 days for full coverage (Consumer Reports Warranty Guide ✔️).
👉 My take: Goodman’s lifetime coverage on compressors and heat exchangers is hard to beat if you’re planning to stay in your home long-term.
🌍 Design & Refrigerant
One of the biggest differences in 2025 comes down to refrigerant choice.
-
Goodman: Already using R-32 across many models—lower Global Warming Potential (675 vs. R-410A’s 2,088).
-
Carrier: Transitioning to R-454B in new models.
-
Lennox: Some models shifting to R-32; others to R-454B.
👉 If you want to be future-proof, Goodman’s full adoption of R-32 is a major advantage. It’s efficient, easier to recycle, and meets 2025 EPA standards (EPA – HFC Phasedown ✔️).
🧰 Installation & Service
The best equipment is only as good as its installation. Brand networks matter:
-
Goodman: Parts widely available, large installer network.
-
Carrier: Big dealer network, consistent service.
-
Lennox: More limited dealer network, higher repair costs if proprietary parts are needed.
I’ve heard from neighbors with Lennox systems who waited weeks for specialty parts, while Goodman parts were available in days.
💵 Incentives & Rebates
Since cost is such a big factor, rebates matter.
-
Goodman: Many models qualify for federal tax credits + local utility rebates if SEER2 ≥ 15.2 (north) or 14.3 (south).
-
Carrier & Lennox: Premium models usually qualify for maximum credits thanks to ultra-high efficiency.
👉 Check your eligibility with the Energy Star Rebate Finder ✔️.
✅ Samantha’s Verdict
Here’s how I break it down after comparing Goodman, Lennox, and Carrier:
-
Goodman: Best for homeowners who want affordability + unbeatable warranties. Perfect if you plan to stay in your home and want reliable performance without overspending.
-
Lennox: Best for homeowners chasing ultra-high efficiency + quiet operation. Ideal if noise and long-term energy savings matter more than upfront cost.
-
Carrier: Best for those who want a balanced option—higher efficiency than Goodman, broader service network than Lennox, and middle-ground pricing.
👉 My personal choice? I went with Goodman because the lifetime warranty and R-32 refrigerant made me feel future-proof without overspending.
🔑 Final Thoughts
So, which brand wins the 5 Ton AC + gas furnace showdown?
-
Goodman = Value King 💵

Lennox = Efficiency Leader ⚡

Carrier = Balanced Choice ⚖️
The best choice really comes down to your budget, efficiency goals, and noise tolerance. With rebates and careful planning, any of these systems can serve your home well for the next two decades.
