❄️ When the summer heat hits hard and you can’t install a window unit, a portable air conditioner (PAC) can be a lifesaver. It’s a compact, movable solution that cools your room without permanent installation. But not all portable ACs are created equal.

✨ What to Consider Before Buying a Portable Air Conditioner
📐 Room Size & BTU Rating
Make sure the unit is powerful enough for your space. Here’s a quick guide:
| Room Size | BTU Recommendation |
|---|---|
| Up to 250 sq ft | 8,000 BTU |
| 250–400 sq ft | 10,000–12,000 BTU |
| 400–600 sq ft | 14,000 BTU+ |
⚠️ Note: New DOE SACC ratings are more realistic but appear lower than old BTU values. Always compare both if listed.
🔄 Single Hose vs Dual Hose
- Single-hose units are cheaper but less efficient—they pull warm air in as they cool.
- Dual-hose systems are more efficient and ideal for larger or sun-exposed rooms.
💧 Drainage System
- Self-evaporating units release moisture with hot air—very low maintenance.
- Manual drainage may require you to empty a tank regularly (annoying in humid areas).
- Hose drain options allow continuous draining through a floor drain.
🔈 Noise Level
Most PACs operate around 50–60 dB. Look for quieter models (below 53 dB) if using in a bedroom or office.
🌡️ Extra Features
- Wi-Fi / Smart control
- Dehumidifier mode
- Timer / Sleep mode
- Remote control
- Auto restart (important during power outages)
