Buying Guide For Through The Wall Heat Pump Air Conditioners
Cooling and Heating Capacity
Choose a unit with cooling and heating BTU capacities that fit your room size. Underpowered units will struggle to maintain comfort, while oversizing can waste energy. Calculate your square footage and refer to product specs for coverage estimates.
Voltage and Electrical Requirements
Verify your home or building’s power supply matches the unit’s voltage and electrical plug type. Commonly, smaller units operate on 115V, while larger PTACs use 208-230V power. Incorrect matching can cause operational issues or safety risks.
Installation Requirements
Some units include wall sleeves and grilles while others require separate purchases. Confirm what accessories are included to avoid additional costs and installation delays. Consider if your wall structure supports through-the-wall installation.
Refrigerant Type and Energy Efficiency
Modern heat pump air conditioners use R-32 refrigerant for better environmental impact and efficiency. Check the Energy Efficiency Ratio (EER) rating to compare operating costs; higher EER means better energy savings.
Additional Features
- Smart controls and remotes: Enable convenient temperature adjustment and scheduling, some even adjust based on room temperature sensing.
- Dehumidification: Units with dry mode improve indoor air quality by reducing excess moisture.
- Backup electric heaters: Ensure warmth during very cold weather when heat pump efficiency drops.
Durability and Brand Support
Opt for reputable brands with strong warranties and customer service. Reliable units minimize downtime and expensive repairs, a critical consideration for commercial or hotel use.
