Alright, let’s jump into it. Picture this — you’re standing in a cramped attic or crawlspace. Maybe you’re dealing with an old, tired vertical unit that’s chugging along and costing you way too much on your utility bills. Time to switch gears. That’s where the Goodman GPCH33631 comes in.
This horizontal powerhouse is built to fit those tight spaces other units can’t. It’s a 3-ton single-phase unit using eco-friendly R-32 refrigerant — a future-proof choice that’s good for the planet and your wallet. From my experience as an HVAC tech, this one’s straightforward to install and super easy to maintain, which is exactly what you want if you appreciate gear that just works.
❄️ Why Choose a 3-Ton Horizontal AC?
If you’re wondering whether this is the right setup for you, here’s the deal: a 3-ton AC unit is just right for most medium-sized homes — we’re talking around 1,800 to 2,200 square feet, depending on your insulation and local climate.
Horizontal AC units fit perfectly in tight spots like attics or crawlspaces — places where a vertical unit just won’t go. Plus, properly sized cooling means you’re not short-cycling the unit (which wastes energy and wears parts faster).
And with a unit like this, you can breathe easy knowing it’s cooling efficiently every time it kicks on.
🧰 Specs & Features at a Glance
Let’s talk specs. The GPCH33631 comes with serious cooling capacity — a full 36,000 BTUs — powered by a scroll compressor that’s as quiet as it is reliable. It runs on 208/230 volts, single-phase, so it integrates smoothly into most standard home setups.
And the real star here? R-32 refrigerant. It’s better for the environment — one-third the global warming potential of R-410A — and it supports higher efficiency. That means you’ll enjoy lower bills without feeling like you sacrificed comfort.

🌍 R-32 Refrigerant & Energy Efficiency
Let’s talk green cooling. R-32 refrigerant is quickly becoming the go-to choice for HVAC pros who care about sustainability. Why? Because it cools more efficiently and doesn’t heat up the planet like the refrigerants of the past.
That translates to a system that runs leaner — using less energy and lowering your electric bill — without losing cooling power. The U.S. Department of Energy even breaks down the data on why R-32 is a smart switch.
And don’t forget, an energy-smart unit can often qualify for rebates — the EnergyStar rebate finder is a quick way to check what’s available in your area.
🔧 Installation & Setup Tips
Installing a horizontal unit like this one is an art — and a bit of a science. Here’s what I recommend:
Make sure the unit is level and stable. Vibration and noise often come from a poor mounting surface — so give it a solid platform. Keep refrigerant lines short and straight wherever you can. This will improve refrigerant flow and reduce pressure drop across the system.
And remember to pull a deep vacuum before you charge the refrigerant — that’s crucial to removing moisture, which can wreak havoc inside your system. It’s also smart to use nitrogen purge while brazing copper to avoid soot buildup inside the pipes.

🧼 Maintenance & Longevity
Want to keep this unit going strong for 15 to 20 years? Regular upkeep is your best friend.
Change your air filters every few months — more often if you have pets or allergies. Check that your coils and drains stay clean and clear of debris. Every year, it’s a good idea to have a pro come by and check refrigerant pressures, inspect wiring, and clean the outdoor coil.
Goodman OEM parts, like capacitors and contactors, are easy to find through suppliers like HVACPartsShop, so replacements and upkeep won’t break the bank.
🔍 Troubleshooting Common Issues
Here’s a quick cheat sheet if you ever notice something off:
If the unit isn’t cooling well, start with the basics — check your refrigerant level and look for obvious airflow restrictions like a clogged filter or a blocked return. Ice on the coil? That could mean low refrigerant or poor airflow. If it’s cycling too often, double-check your thermostat settings and see if the drain switch is tripping due to water buildup.
And don’t sweat the small stuff — most of these problems can be caught and fixed early with a little regular TLC.
⚖️ How It Stacks Up to the Competition
When you put Goodman up against other big-name brands like Carrier or Trane, you quickly see where it shines. Sure, those premium brands offer nice features and long warranties — but they also come with a premium price.
Rheem is a solid mid-range option too, but most of their horizontal units still use R-410A refrigerant — so they’re missing the efficiency and environmental benefits of R-32. That’s why the GPCH33631 is my go-to recommendation for most homeowners: dependable, future-focused, and affordable.
🌿 Energy-Saving Strategies
You can supercharge your savings by pairing this unit with other smart energy moves. Insulate your attic to at least R-38 or better — the U.S. Department of Energy says proper insulation can slash cooling loads by up to 20%.
And don’t overlook the power of a smart thermostat — they make a big difference by learning your schedule and dialing back cooling when you don’t need it. Installing zoning dampers and balancing airflow can also reduce energy consumption across different rooms, especially if you live in a larger home.
✅ Buying Guide
Before you buy, make sure you’ve sized your system properly for your space — a 3-ton unit is a great fit for most mid-sized homes. Check that your ductwork is ready for horizontal setup and that your electrical panel can support a 30-amp breaker.
