# 15 Ways to Reduce Your HVAC Energy Costs
HVAC systems account for nearly half of your home's energy use. These strategies can significantly reduce your bills while maintaining comfort.
Quick Wins (No Cost)
1. Adjust Your Thermostat - Set to 68°F in winter, 78°F in summer - Use programmable schedules - Don't heat/cool when away
Savings: Up to 10% annually
2. Use Ceiling Fans - Summer: Counter-clockwise direction - Winter: Clockwise on low - Turn off when leaving room
Savings: Allow 4°F higher thermostat setting
3. Close Blinds and Curtains - Summer: Close during peak sun - Winter: Open south-facing windows, close at night
Savings: 5-15% on cooling costs
4. Seal Obvious Air Leaks - Close fireplace damper when not in use - Seal gaps around windows - Use door sweeps
Savings: Varies, often significant
5. Optimize Vent Usage - Keep all vents open (closing them causes problems) - Ensure furniture doesn't block vents - Don't cover returns
Low-Cost Improvements
6. Replace Air Filters Regularly - Check monthly, replace when dirty - Consider MERV 8-11 for efficiency - Dirty filters increase energy use 5-15%
Cost: $5-20 per filter
7. Apply Weatherstripping - Seal gaps around doors - Check and replace window seals - Address obvious drafts
Cost: $10-50
8. Add Door Sweeps - Simple, effective air sealing - Available at hardware stores
Cost: $10-30 per door
9. Insulate Accessible Ductwork - Focus on ducts in unconditioned spaces - Use duct insulation wrap
Cost: $100-300 DIY
10. Use a Smart Thermostat - Learns your schedule - Optimizes heating/cooling - Remote access for adjustments
Cost: $100-250
Moderate Investments
11. Schedule Professional Maintenance - Annual tune-ups improve efficiency - Prevent costly breakdowns - Maintain manufacturer warranty
Cost: $100-200 per year
12. Seal Ductwork Professionally - Typical homes lose 20-30% through duct leaks - Professional sealing very effective
Cost: $300-1,000
13. Add Attic Insulation - Major energy saver - Good DIY project - Aim for R-38 to R-60
Cost: $500-1,500
14. Install a Zoning System - Heat/cool only occupied areas - Reduces energy waste - Works with existing system
Cost: $2,000-3,500
Major Upgrades
15. Upgrade to High-Efficiency Equipment - New systems use 30-50% less energy - Rebates available - Lower operating costs for years
Cost: Varies by system
Bay Area-Specific Tips
Coastal Areas - Use ceiling fans more, AC less - Natural ventilation effective most days - Focus on heating efficiency
Inland Areas - Prioritize cooling efficiency - Shade windows from afternoon sun - Consider whole-house fans
All Areas - Take advantage of PG&E rebates - Consider time-of-use rate impacts - Use fans before AC kicks on
Seasonal Strategies
Summer - Pre-cool home in morning - Use fans first, AC second - Close blinds on sunny windows - Grill outside to reduce cooking heat
Winter - Let sun warm home during day - Lower thermostat at night - Use space heaters strategically - Reverse ceiling fans
Measure Your Progress
Track Energy Use - Review PG&E bills monthly - Compare year-over-year - Use PG&E online tools
Common Benchmarks | Action | Expected Savings | |--------|------------------| | Thermostat adjustment | 10% | | Sealing air leaks | 5-15% | | Professional tune-up | 5-10% | | Upgrading equipment | 30-50% |
