How should I compare winter thermostat settings?

Thermostat settings should account for occupancy, comfort, equipment, and manufacturer guidance. A programmable or smart thermostat can automate an agreed schedule; compare actual utility use before and after changes.

How often should I change my furnace filter in winter?

Inspect the filter regularly and follow the filter and equipment manufacturers' replacement guidance. Filter type, heating use, pets, dust, and indoor-air conditions affect the interval.

Are space heaters cheaper than running my furnace?

Not usually. Electric space heaters cost roughly three times more per BTU than natural gas heating in the PECO service area. A single 1,500-watt space heater running 8 hours a day adds about $40-50 per month to your electric bill. The only scenario where a space heater makes financial sense is if you are heating one small room and can turn off your central heating entirely, which is impractical for most Warminster homes.

How much can I save by upgrading to a high-efficiency furnace?

AFUE is an equipment efficiency rating, not a promise of household savings. Actual operating cost depends on the home's heating load, installation, controls, fuel price, weather, duct condition, and use. Compare proposal-specific operating-cost estimates and their assumptions without treating projected savings as guaranteed.

How can I evaluate air sealing?

Air leakage can affect heating and cooling loads. Identify leakage paths, address them with materials appropriate to the location, maintain required ventilation and combustion air, and compare measured utility use and comfort after the work.

How to Keep Heating Bills Low in Bucks County PA

Summary: Practical tips to reduce heating bills for Bucks County PA homeowners. Thermostat settings, insulation, furnace maintenance, and energy-efficient upgrades.

Published 2026-02-16.

Start with settings and low-risk maintenance

Use a thermostat schedule that fits occupancy, install the correct clean filter, keep registers clear, close fireplace dampers when safe and unused, and follow equipment maintenance guidance. Avoid extreme setbacks that conflict with the system or household needs.

Reduce the home's heating load

Air sealing and insulation can reduce heat loss when moisture, ventilation, and combustion safety are considered. Prioritize measured or professionally assessed leakage rather than sealing random openings around combustion equipment.

Investigate unexplained usage changes

Compare weather, thermostat changes, utility rates, occupancy, equipment runtime, auxiliary heat, and maintenance history. A sudden increase may warrant checking controls, airflow, ducts, heat-pump backup operation, or combustion performance.
