Best R-32 PTAC Brands Compared: GE Zoneline vs. Amana vs. Hotpoint
Tony Marino’s Hands-On Review of the Top R-32 Packaged Terminal Air Conditioners
🧰 Tony’s Intro: Three Names, One Big Question
When I walk into a hotel or apartment retrofit these days, I usually see one of three brand names on the wall: GE Zoneline, Amana, or Hotpoint.
They’ve all joined the R-32 refrigerant transition, ditching R-410A for cleaner, more efficient systems — but they’re not all built the same.
Some run quieter, others handle coastal air better, and a few make you want to pull your hair out when you’re sourcing replacement parts.
I’ve installed and serviced all three dozen times. So this isn’t marketing fluff — this is the straight, Tony Marino truth from the guy who’s actually had these units on the bench.
Let’s break it down: who builds it best, who’s easiest to live with, and who’s worth your money.
⚙️ 1. The R-32 Difference — Why It Matters for All Three
Before we get into brand talk, let’s level-set on what R-32 brings to the table.
-
Global Warming Potential (GWP): 675 (⅓ of R-410A’s 2,088).
-
Better heat transfer means lower compressor load.
-
Higher capacity per pound: So units need less refrigerant.
-
Quieter and more efficient cycles.
All three brands use R-32 scroll compressors designed for stable operation and lower discharge temperatures. That gives you a quieter startup, steadier airflow, and longer life expectancy.
👉 Tony’s Tip: When you see R-32 on the label, you’re not just buying eco-friendly — you’re buying cooler-running, longer-lasting equipment.
🧱 2. Brand Backgrounds: Who’s Who
| Brand | Parent Company | Origin | Focus |
|---|---|---|---|
| GE Zoneline | GE Appliances (Haier) | USA | Commercial hotels & apartments |
| Amana | Goodman / Daikin | USA | Hospitality & multifamily |
| Hotpoint | GE Appliances | USA | Budget residential & light commercial |
All three share manufacturing roots in the U.S., but their priorities differ:
-
GE Zoneline is engineered for hotels that care about noise, efficiency, and reliability.
-
Amana targets durability and long-term cost control.
-
Hotpoint focuses on affordability without sacrificing Energy Star compliance.

🔊 3. Noise Level Comparison
If you’ve ever tried to sleep next to a buzzing PTAC, you know sound is everything.
| Brand | Indoor Noise (Low Fan) | Outdoor Noise | Tony’s Notes |
|---|---|---|---|
| GE Zoneline | 44–48 dB | 52–56 dB | Smooth inverter ramp-up |
| Amana | 42–46 dB | 50–54 dB | Quiet coil design |
| Hotpoint | 46–50 dB | 52–58 dB | Slightly louder under load |
👉 Tony’s Verdict: Amana wins for whisper-quiet operation, especially in smaller hotel rooms. GE follows close behind with refined airflow control. Hotpoint’s fine for residential spaces, but not if silence is golden.
🌡️ 4. Heating Performance in Winter
R-32 handles cold air better than R-410A, but coil design still makes or breaks winter comfort.
| Brand | Heating Type | Low Temp Operation | Notes |
|---|---|---|---|
| GE Zoneline | Heat pump + 3.5–5 kW strip | Down to 20°F | Seamless auto-switch |
| Amana | Heat pump + 3.5–5 kW strip | Down to 25°F | Dual-thermostat logic |
| Hotpoint | Electric resistance only | N/A | Reliable but energy-hungry |
👉 Tony’s Field Take: GE’s adaptive logic handles northern winters best — no cold-air surprises between defrost cycles. Amana is strong in mixed climates. Hotpoint? Reliable backup heat, but expect higher electric bills.
💨 5. Cooling Efficiency & SEER Equivalents
While PTACs don’t use SEER ratings like split systems, we can compare EER (Energy Efficiency Ratio) and CEER (Combined EER).
| Brand | EER | CEER | Energy Star? |
|---|---|---|---|
| GE Zoneline | 10.6–11.2 | 9.9–10.5 | ✅ |
| Amana | 10.4–11.0 | 9.6–10.2 | ✅ |
| Hotpoint | 10.0–10.4 | 9.3–9.8 | ✅ (entry tier) |
👉 Tony’s View: All three meet Energy Star minimums, but GE and Amana squeeze extra savings through variable-speed motors and smart defrost algorithms.
