Buying Guide: Choosing The Best Through-The-Wall Heat Pump Air Conditioner
When selecting a through-the-wall heat pump air conditioner, it’s important to consider several factors to ensure you get the right unit for your space and needs.
Cooling and Heating Capacities
Determine the size of the space to be cooled and heated. For small rooms, units with 8,000 to 10,000 BTU cooling capacity suffice, while larger rooms or open areas may require 15,000 BTU or more. Heating capacity varies; some units include supplemental or electric backup heating which is crucial for colder climates.
Voltage and Electrical Requirements
Check your existing electrical setup. Common voltages are 115V for smaller units and 230/208V for higher-capacity models. Ensure the unit’s voltage matches your power outlets, and verify if the unit comes with specific plugs or breakers for safety.
Installation Features
Many units require a compatible wall sleeve, either included or sold separately. Precise wall sleeve sizing and proper installation materials are essential for efficiency and reducing drafts. Some models are compatible with standard sleeves facilitating easier replacement or upgrades.
Refrigerant Type and Energy Efficiency
Look for models using modern refrigerants like R-32, which offer better energy efficiency and are more environmentally friendly. Consider the unit’s Energy Efficiency Ratio (EER) to compare power consumption. Higher EER ratings indicate better efficiency.
Additional Functionalities
- Smart Controls: Wireless kits and smart remotes enable easier monitoring and adjustment.
- Dehumidification: Some units can remove moisture, improving air comfort.
- Fan Speeds and Modes: Multiple speeds and modes allow tailored operation (energy saver, dry mode, fan-only).
- Heating Type: Heat pumps provide efficient heating in mild to moderate cold, supplemented by electric heaters in some models.
Brand Reliability and Support
Choose established brands with good customer support, reliable parts availability, and positive user feedback. This is especially important for long-term maintenance and warranty services.
