Buying Guide: Key Considerations For Cooling An Old House
- Room size and layout: Old houses often have irregular rooms and thick walls. Choose BTU ratings that adequately cover the largest space you need to cool, or pick units with multi-room capability.
- Ventilation and installation: Window kits and exhaust hoses are essential. Prefer models with straightforward DIY installation if you lack window access or ductwork.
- Energy efficiency: Look for CEER or similar efficiency metrics. In drafty homes, energy-efficient units help reduce operating costs over summer.
- Mobility: Casters and handles matter when moving units between rooms with different layouts or stair access.
- Humidity management: In older homes, dehumidification can improve comfort—particularly in basements or humid climates.
- Climate suitability: Evaporative coolers work best in dry climates; in humid regions they may be less effective.
- Noise levels: Sleep or quiet modes are valuable for bedrooms or home offices in older houses.
