Why Your Heat Pump Is Using More Power in Winter (And What Nova Scotia Homeowners Can Do About It)

Cold Nova Scotia winters can expose hidden efficiency problems in heat pump systems. Many homeowners notice rising power bills even though they upgraded specifically to save money. In most cases, higher electricity usage is not caused by the heat pump itself — it is caused by airflow restrictions, insulation gaps, and missed seasonal maintenance.
Modern cold-climate heat pumps are extremely efficient, but only when air can circulate freely and the system is operating within its designed load range. Small issues compound quickly during long winter run times.
Why does my heat pump use more electricity in winter?
In winter, your system runs longer to maintain indoor comfort. If airflow is restricted by dirty filters, blocked outdoor coils, or dust-filled indoor units, the system works harder and draws more power to compensate.
Can insulation problems increase heat pump power usage?
Yes. Heat pumps are highly sensitive to heat loss. Drafty attics, unsealed crawl spaces, and poorly insulated basements cause warm air to escape, forcing the heat pump to run continuously. Many Nova Scotia homes lose a significant amount of heat through the attic alone.
Does skipping maintenance reduce efficiency?
Yes. Heat pump coils accumulate dust, pollen, and moisture buildup over time. This restricts heat transfer and increases compressor workload. Annual professional servicing restores airflow and efficiency.
Should outdoor heat pump units be cleared in winter?
Yes. Snow buildup, leaves, and ice around outdoor units block airflow and reduce heat exchange, which increases electrical demand. Keeping a clear zone around the unit improves performance and prevents premature wear.
When should you book heat pump servicing?
Late fall is ideal before heavy winter usage begins. Spring servicing is also recommended to remove winter buildup and prepare the system for summer cooling.
Homeowners across Nova Scotia can dramatically reduce winter electricity costs by combining proper insulation upgrades with regular professional servicing.
