    Quick Savings Tips

    Schedule Annual Tune-Up

    A $299 tune-up can improve efficiency by 10-15%, saving $100-300/year.

    Upgrade to Smart Thermostat

    Smart thermostats can reduce heating costs by 10-12% annually.

    Seal Ductwork

    Leaky ducts waste 20-30% of heated air. Sealing pays for itself in 1-2 seasons.

    Consider High-Efficiency Replacement

    Upgrading from 80% to 96% AFUE can cut heating costs by 20%.

    Common Causes of High Heating Bills

    Dirty Air Filter

    Low PriorityDIY Fix

    Clogged filter forces furnace to work harder and run longer.

    Solution: Replace air filter monthly during heating season. A clean filter can reduce energy use by 5-15%.

    Thermostat Settings

    Low PriorityDIY Fix

    Thermostat set higher than necessary or malfunctioning.

    Solution: Lower thermostat by 1-2 degrees or install a programmable/smart thermostat.

    Air Leaks and Poor Insulation

    Low PriorityDIY Fix

    Heat escaping through gaps, windows, or inadequate insulation.

    Solution: Seal gaps around windows/doors, add weatherstripping, check attic insulation.

    Blocked or Closed Vents

    Low PriorityDIY Fix

    Closed vents in rooms create pressure imbalance and inefficiency.

    Solution: Open all supply vents throughout the home, even in unused rooms.

    Aging Furnace (15+ Years)

    Medium PriorityCall Pro

    Older furnaces naturally lose efficiency over time.

    Solution: Professional efficiency assessment; consider replacement if AFUE is below 80%.

    Dirty Burners or Heat Exchanger

    Medium PriorityCall Pro

    Buildup reduces heat transfer efficiency.

    Solution: Professional cleaning during annual tune-up.

    Short Cycling

    Medium PriorityCall Pro

    Furnace turning on/off frequently wastes energy on startup cycles.

    Solution: Professional diagnosis to identify cause of short cycling.

    Ductwork Leaks

    Medium PriorityCall Pro

    Heated air escaping through gaps or holes in ductwork.

    Solution: Professional duct inspection and sealing. Can improve efficiency by 20-30%.
