How to choose the right one
Check your outlet voltage
Your home’s electrical outlets dictate which unit you can install. Most standard outlets provide 115 volts, which matches the 12,000 BTU wall unit. This model is ideal for bedrooms or baby rooms where quiet operation matters. If you have a 230-volt outlet, you can use the more powerful 14,000 BTU wall unit or the 23,200 BTU window unit. Using the wrong voltage can damage the unit or prevent it from starting. Always verify your outlet type before buying.
Match BTU to room size
Cooling power must match your room’s square footage to work efficiently. The 23,200 BTU model covers up to 1,500 square feet, making it suitable for large open living areas. The 14,000 BTU unit handles up to 700 square feet, fitting medium-sized rooms or garages. The 12,000 BTU unit is best for spaces up to 550 square feet. Choosing a unit with too much power for a small room causes rapid cycling. Selecting too little power leaves the room warm. Check your room dimensions first.
Decide on heating needs
Some units provide supplemental heat, while others only cool. The 23,200 BTU window unit includes a heating mode, allowing you to use it year-round. This is useful if you want a single appliance for multiple seasons. The other two models listed focus on cooling and dehumidifying. They do not offer heating functions. If you live in a climate with mild winters, a cooling-only unit may suffice. If you need warmth during cold spells, prioritize the model with heating capabilities.
Consider installation location
Decide if you prefer a window or wall mount. The top pick is a window unit, which fits standard window frames. The other two models are wall-mounted units. Wall mounts save window space and can be installed in new construction or retrofitted walls. They are often better for garages or rooms without suitable windows. Check your available space and mounting options before purchasing. Window units require a sill or bracket. Wall units need a hole in the wall. Choose based on your home’s structure.
Verify remote control presence
All models in this list include remote controls for convenience. This allows you to adjust temperature and modes from a distance. You do not need to reach the unit to change settings. This is helpful for wall-mounted units that are high up. It also adds comfort for window units. Ensure the remote batteries are included or easy to replace. Remote control is a standard feature here, so you do not need to compromise on this convenience for a lower price point.
