Buying Guide
What type should you choose for all-season heating and cooling?
- Mini split vs. window unit: Mini splits offer better efficiency and flexible placement but require professional installation. Window units are easier to install but may be less efficient and block some light.
- Room size and BTU: Match BTU to room size for effective comfort. Oversized units waste energy; undersized units struggle to reach set temperatures.
- Heat source: Look for heat pump capability for year-round use. Supplemental heat is useful but not a primary heat source in cold weather.
- Smart controls: App or voice control adds convenience and can improve long-term energy savings.
- Energy efficiency: Check ENERGY STAR certification and inverter technology for lower operating costs.
Practical checklist
- Ceiling height, window space, and exterior wall clearances.
- Electrical service requirements and circuit capacity.
- Noise levels in the sleeping area and living room.
- Maintenance: washable filters and easy front-panel access.
