HVAC Energy Savings Tips

Every 1°F adjustment saves approximately 3% on energy costs.

1. 1Replace air filters regularly — dirty filters make your system work 15% harder
2. 2Seal air leaks around windows, doors, and ductwork
3. 3Use ceiling fans to circulate air (counter-clockwise summer, clockwise winter)
4. 4Keep vents and registers unblocked by furniture or curtains
5. 5Close blinds/curtains during hot summer days
6. 6Add insulation to attic and walls if needed
7. 7Use a programmable or smart thermostat
8. 8Get annual professional maintenance tune-ups

• Change air filters every 1–3 months
• Clean outdoor condenser coils annually
• Clear debris around outdoor unit (2ft clearance)
• Clean condensate drain line with vinegar
• Seal visible duct leaks with mastic or metal tape
• Insulate exposed ductwork in unconditioned spaces
• Check and replace weather stripping
• Clean supply and return vents

Consider upgrading your HVAC system if:

• Your system is 15+ years old
• Repair costs exceed 50% of replacement cost
• Your energy bills keep increasing year over year
• Your home has uneven temperatures room to room
• Your system uses R-22 refrigerant (phased out)
