Lennox Air Conditioner SEER2 Ratings: Impact On Cost And Savings
SEER2 (Seasonal Energy Efficiency Ratio 2) is the current rating standard for air conditioners, measuring cooling output relative to electricity use. The higher the SEER2, the more energy efficient—and expensive—the unit.
- Entry SEER2 (13.4-16): Lower price, meets minimum federal standards.
- Mid-Range SEER2 (17-20): Higher upfront cost, notable savings on electricity bills.
- High-End SEER2 (21+): Premium cost, highest potential for long-term savings and rebates.
Consider your climate zone and local electricity rates when determining if a higher-SEER2 unit will pay off over time.
What Factors Determine The Right Lennox AC Size?
Proper sizing is crucial for efficient cooling and cost management. Selecting the right air conditioner size depends on:
- Home Square Footage: Larger homes require larger (tonnage) units.
- Insulation Quality: Well-insulated homes can often use smaller ACs.
- Climate: Hotter regions need more cooling power.
- Ceiling Height And Windows: Tall ceilings and large windows can increase cooling demands.
Professional load calculation (Manual J) is recommended for accurate sizing, as oversizing or undersizing can increase costs and reduce comfort.
