How to Lower Your Heating Bill

Heating accounts for 40 to 50 percent of annual utility expenses in most American homes. Whether you use a gas furnace, electric heat pump, or oil boiler, there are proven strategies to reduce those costs without sacrificing comfort.

Quick Wins: No-Cost Strategies

Lower Your Thermostat

For every degree you reduce the setpoint, you save approximately 1 to 3 percent on your heating bill.

Recommended settings:

When home and awake: 68 degrees
When sleeping: 60 to 65 degrees
When away: 55 to 60 degrees

Use Sunlight Strategically

Open curtains on south-facing windows during the day. Close them at night to insulate against cold surfaces.

Block Drafts

Place a draft snake at the base of exterior doors. Apply adhesive-backed foam weatherstripping for a better seal.

Close Unused Rooms

Close supply registers and doors in rarely-used rooms. Do not close more than 20 percent of registers, as excessive closure can damage the heat exchanger.

Use Ceiling Fans in Reverse

Set ceiling fans to rotate clockwise at low speed. This pushes warm air near the ceiling down into the living space.

Low-Cost Improvements

Programmable or Smart Thermostat

Automatic temperature adjustments eliminate human error. Estimated savings: $50 to $150 per year. Many utilities offer rebates of $50 to $100 on smart thermostats. The Google Nest Learning Thermostat builds a schedule automatically over the first week — no manual programming needed. For households that want remote room sensors included out of the box, the Ecobee SmartThermostat Premium is the better choice.

Weatherstripping and Caulking

Air leaks account for 25 to 40 percent of heating energy loss. A $20 to $40 investment can reduce heating costs by 10 to 20 percent. Focus on door frames, window sashes, utility penetrations, and attic hatches.

Window Insulation Film

For older or drafty windows, shrink-fit film creates an additional air barrier that reduces heat loss through glass by up to 70 percent. Costs about $5 to $10 per window.

Door Sweeps

Install door sweeps on exterior doors to close the gap between the door and threshold. A roll of adhesive foam weatherstripping costs under $10 and seals most standard door frames in under 30 minutes.

Medium-Cost Investments

Attic Insulation Upgrade

The Department of Energy recommends R-49 to R-60 for attics in northern climates and R-38 for southern climates. Blown-in insulation costs $1 to $2 per square foot installed and typically pays for itself within 2 to 5 years.

Duct Sealing and Insulation

Professional duct sealing costs $300 to $800 but can reduce heating and cooling costs by 15 to 25 percent.

High-Impact Upgrades

Upgrade to a High-Efficiency Furnace

Replacing a 15 to 20-year-old furnace with a modern 95+ percent AFUE model can reduce heating costs by 20 to 30 percent.

Install a Heat Pump

Heat pumps can reduce heating costs by 30 to 50 percent compared to electric resistance and 10 to 30 percent compared to gas furnaces, depending on local rates.

Monitor and Adjust

Track your energy bills monthly and compare to the same month in previous years. Many utilities provide online tools that normalize for temperature.

The key to lowering your heating bill is combining multiple strategies. Start with the free and low-cost steps, then invest in larger improvements as your budget allows.
