Window Air Conditioners FAQ
Most window AC installations are DIY-friendly. You'll need another person to help lift the unit, basic tools, and about 30-60 minutes. Ensure your window can support the weight and that you have an appropriate electrical outlet nearby.
SEER (Seasonal Energy Efficiency Ratio) measures AC efficiency. The minimum for new units is 14 SEER. We recommend 16+ SEER for moderate climates and 18+ SEER for hot climates where AC runs frequently. Higher SEER costs more upfront but saves on energy bills.
No, window ACs are designed primarily for double-hung (vertical sliding) windows. Most units fit windows 23-36 inches wide. Casement (crank-out) windows require special units or may not be compatible. Always check dimensions before purchasing.
With proper maintenance: window ACs last 10-15 years, portable ACs 5-10 years, and mini splits/central AC 15-20 years. Factors affecting lifespan include usage frequency, maintenance, climate, and build quality.
