Let’s have a real talk about air conditioner compressors — specifically those big 5 ton units. I’ve worked on more than I can count, from old-school R-22 models to brand-new high-efficiency setups. And let me tell you: not all 5 ton compressors are created equal. If you’re trying to decide whether to repair your aging 5 ton R-22 compressor or upgrade to something more efficient, like an R-32 system, I’ve got your back.
Today, I’m going to break it all down — what 5 ton compressors do, why they matter, and how newer systems like the Goodman 3 Ton 14.5 SEER2 R-32 Bundle are leaving the old R-22 dinosaurs in the dust. Let’s get into it.
What Is a 5 Ton Air Conditioner Compressor, Really?
The air conditioner compressor is the heart of any cooling system — it circulates refrigerant through the lines, which is how the system pulls heat out of your home and dumps it outside.
When we say a “5 ton compressor,” we’re not talking weight — we’re talking cooling capacity. One “ton” equals 12,000 BTUs, so a 5 ton unit pumps out 60,000 BTUs of cooling per hour. That’s typically used in homes around 2,500–3,000 square feet, though it depends on insulation, sun exposure, and ductwork.
If you're running a 5 ton air conditioner compressor, it’s likely keeping a big household or light commercial space cool. But here's the catch: if it's more than 10–15 years old and still running on R-22 refrigerant, you’re sitting on a ticking time bomb.
The R-22 Phase-Out: Why It Matters to Your 5 Ton Compressor
Let’s get one thing straight: R-22 refrigerant (a.k.a. Freon) is banned for production in the U.S. and most of the world. It's a high-global-warming-potential (GWP) chemical that’s been phased out for environmental reasons.
That means any system with an R-22 5 ton compressor is now running on borrowed time.
-
You can’t legally recharge it with fresh R-22 unless you find reclaimed or recycled stock.
-
If the compressor goes bad — and trust me, they do — replacing it with another R-22 unit will be costly and short-lived.
-
You’ll also struggle to find replacement parts or qualified techs willing to work on these units.
If you’re still relying on an R-22 compressor, it’s like driving a car that runs on leaded gasoline — outdated, inefficient, and unsupported.
Repairing vs. Replacing a 5 Ton Compressor
Let’s say your 5 ton unit isn’t cooling like it used to. Maybe the compressor’s starting to fail. You’ve got two options:
1. Repair or Replace the Compressor Only
You could try replacing the compressor only (if you can find one), but it’s going to run you $2,000–$3,000 when you factor in parts and labor. That doesn’t even guarantee your old condenser, coil, or line set won’t fail next.
Also, keep in mind:
-
The rest of your system is still R-22
-
Efficiency is nowhere near modern SEER2 standards
-
Your utility bills are probably sky-high
2. Upgrade to a Modern SEER2 System with R-32
This is where smarter homeowners are heading. Upgrading to a new system like the Goodman 3 Ton 14.5 SEER2 R-32 system gives you:
-
A more efficient compressor that draws less power
-
R-32 refrigerant, which has 1/3 the GWP of R-410A
-
Compatibility with 2025+ environmental regulations
-
A brand new condenser, coil, and air handler built to work together
5 Ton vs. 3 Ton: Do You Really Need That Much Cooling?
You might be surprised here. A lot of older homes were over-sized when the AC was first installed. Contractors used a rule of thumb — like “a ton for every 500 square feet” — without doing proper Manual J load calculations.
If you’ve upgraded windows, insulation, or roofing since then, your home’s actual load may have dropped. That means you could now get away with a 3 ton or 3.5 ton system without sacrificing comfort — and you’ll save big on energy.
Want to know for sure? Use a BTU load calculator or talk to your HVAC pro about a Manual J analysis.
What Makes Modern Compressors So Much Better?
Let’s compare that old 5 ton R-22 compressor with today’s technology. Here’s what you get when you go with a system like Goodman’s latest:
| Feature | Old 5 Ton R-22 Compressor | Modern R-32 System (e.g. Goodman) |
|---|---|---|
| Refrigerant | R-22 (banned) | R-32 (low GWP, high efficiency) |
| SEER Rating | 8–10 (if you’re lucky) | 14.5 SEER2+ |
| Compressor Type | Single-stage | Scroll compressor |
| Environmental Impact | High | Reduced by 68% |
| Noise Level | Loud | Whisper-quiet |
| Warranty Support | None or expired | Up to 10 years |
| Energy Costs | High | 30–50% lower on average |
And let me be clear: Goodman knows how to build tough, reliable compressors. Their units have been going strong for decades, but now they’re leading the pack with R-32 and SEER2-compliant systems.
Choosing the Right System: R-32 vs. R-410A
I get a lot of questions about refrigerants, especially as the market shifts from R-410A to R-32. Here’s the deal:
-
R-410A is still widely used, but it’s getting phased out starting in 2025 because of its high GWP.
-
R-32 is the upgrade — it’s easier to recycle, more efficient thermodynamically, and already standard in Europe and Asia.
-
R-32 systems use less refrigerant charge, making them more compact and efficient overall.
That’s why it makes sense to choose a system that already meets the upcoming EPA AIM Act requirements now instead of scrambling later.
What About Dual Compressor Systems?
Some larger homes and commercial buildings run dual HVAC systems, meaning two compressors to cool different zones. You’ll usually find this in homes over 3,500 square feet or with split-level layouts.
But here’s the kicker — you don’t always need two 5 ton units.
-
With proper zoning and smart thermostats, many homes can run one 5 ton unit and a smaller 2.5–3 ton backup.
-
Or better yet, upgrade to a multi-zone variable speed system for more flexibility and higher efficiency.
Check out how modern zoning works from Carrier’s Infinity System — a great example of advanced cooling control.
Why I Recommend Goodman for Compressor Replacements
Goodman systems are tough, reliable, and budget-friendly. I’ve been installing and servicing them for over 20 years. If you're replacing an old 5 ton compressor, Goodman gives you all the right features:
-
Scroll compressors: Fewer moving parts, better reliability
-
Factory-matched coils: Designed to work together seamlessly
-
Quiet operation: No more rattling compressor cabinets
-
Smart diagnostics: Easier service and fewer breakdowns
And when you go with a full bundle like the Goodman 3 Ton 14.5 SEER2 R-32 System, you get everything built and warrantied to run as a complete unit.
Final Thoughts: Upgrade Smart or Stay Stuck?
Here’s my two cents as a tech who’s seen every kind of system on the market:
-
If your 5 ton compressor is still using R-22, it’s time to replace the entire system.
-
Don’t throw good money after bad by patching a dying unit.
-
R-32 systems like Goodman’s are more efficient, eco-friendly, and future-ready.
-
You might not even need a full 5 ton setup — get your home evaluated!

The bottom line? Compressors are the workhorses of your cooling system — but even the strongest ones can’t keep up forever. Make the smart move now, and save yourself headaches (and cash) down the road.
Stay cool out there.
