Buying Guide
How Much Cooling Capacity Do I Need?
Choose capacity by room size, insulation, ceiling height, and sun exposure. Many listings here specify 12,000 BTU for spaces up to 750 sq. ft.; use that as a general guide but adjust upward for very sunny or poorly insulated rooms.
What SEER or SEER2 Rating Should I Prefer?
SEER/SEER2 measures seasonal efficiency. Higher numbers indicate better efficiency and lower running costs. Select higher SEER/SEER2 units if you run the system many hours per day or live where cooling/heating seasons are long.
115V Or 230V: Which Is Right?
- 115V units typically plug into standard household circuits and may be easier for DIY installs in single-room settings.
- 230V units can deliver more stable power for continuous use and may require professional electrical wiring.
- Choose based on existing electrical panel capacity and installer recommendations.
DIY Installation Versus Professional Installation?
Some models include DIY-friendly kits and pre-charged refrigerant lines, but many require vacuumizing and refrigerant handling that needs specialized tools. Choose professional installation if you lack HVAC experience or if local codes require licensed technicians.
Which Refrigerant Should I Choose?
Look for units that use modern refrigerants like R32 to reduce environmental impact. Confirm refrigerant type in the product listing and ensure installers are certified to handle it safely.
Smart Features, Noise, and Air Quality
- WiFi and Alexa support offer remote control and integration with home automation.
- Noise levels matter for bedrooms—look for models listing dB levels or “silent” modes.
- Air cleaning modes (PM2.5, ions) help with indoor pollutants but review manufacturer descriptions for exact functionality.
