Buying Guide
What should you consider when choosing a bonus room heating and cooling unit?
- Room size and BTU needs: Match the unit’s cooling and heating BTU to the square footage to avoid overworking or underperforming equipment.
- Portability vs. stability: Portable units offer flexibility if you move rooms; window-mounted or through-wall units save space but are less mobile.
- Heating capability: If you need year-round comfort, prioritize units with reliable heating or heat pump functions and check operating temperatures.
- Energy efficiency: Look for Energy Star rated models and inverter or variable-speed technology to reduce long-term energy costs.
- Controls and connectivity: Apps, remotes, and voice control (Alexa/Google Assistant) can simplify daily use in a busy space.
- Moisture control: In spaces prone to humidity, dehumidification performance matters for comfort and mold prevention.
- Installation and maintenance: Consider window kits, hose lengths, and filter accessibility for easy setup and upkeep.
