As temperatures drop across Whatcom County, homeowners are firing up their furnaces — and often seeing their energy bills climb. Local heating experts say a few simple habits and system checks can help residents stay warm without overpaying this winter.

“Clogged or dirty filters can be a common reason why HVAC systems end up with issues and/or failures, especially during a time of need. When systems run, they clean the air, and the filters that catch and filter out particles need to be replaced or cleaned multiple times a year, especially during peak seasons such as summer and winter. Dirty filters cause restricted airflow, which can lead to strain on the mechanical components of your HVAC system and lead to unwanted service calls and lofty utility bills due to increased demand and wear & tear on the system. Replacing your filters regularly and setting reminders on your calendar to replace the filters is something that we highly suggest doing often to protect your investment of a great HVAC system!”

One of the easiest and most effective ways to save is by regularly replacing or cleaning furnace filters. Dirty filters restrict airflow, forcing the system to work harder and use more energy. Most experts recommend checking filters monthly during peak heating season.

Homeowners should also pay attention to thermostats. Lowering the temperature by just a few degrees at night or while away can have a noticeable impact on energy use. Installing a programmable or smart thermostat allows for automatic adjustments that keep heating consistent and efficient.

Sealing air leaks around doors, windows and vents can prevent heat from escaping. Weatherstripping, caulking and proper insulation are small investments that add up to major savings over time.

Feller Heating and Air also recommends annual professional maintenance before the coldest months arrive. During a tune-up, technicians inspect and clean components, check safety controls, and ensure the system is running at peak performance.

For Whatcom County residents, local rebates and energy incentives are often available through utility providers, especially for upgrading to efficient heat pumps or ENERGY STAR–rated equipment.
