💡 Energy Savings Tips
- Upgrade SEER Rating: Switching from SEER 13 to SEER 20 saves ~35% annually—typically pays for itself in 5–7 years.
- Optimize Usage: Use a programmable thermostat to avoid cooling when away or at night. Reduces run time by 20–30%.
- Maintain Your Unit: Clean filters monthly and have annual tune-ups. Dirty filters reduce efficiency by 5–15%.
- Improve Insulation: Seal air leaks and add weatherstripping. Reduces cooling load by 10–20%.
- Use Ceiling Fans: Fans circulate cool air, allowing you to raise the thermostat 2–3°F without discomfort.
- Block Heat: Use blinds, curtains, or window films to reduce solar heat gain by 30–50%.
- Off-Peak Cooling: Pre-cool your home before peak rate hours (if on time-of-use pricing).
