Heat pumps are one of the most efficient ways to heat a home, but winter comfort often comes down to a few simple habits. Many “my heat pump isn’t working” complaints are really about airflow, maintenance, or expectations—especially when the weather turns properly cold.
Efficient temperature habits (without overthinking it)
Aim for steady comfort rather than big swings. Constantly blasting heat to “catch up” can feel inefficient and uncomfortable.
Heat the rooms you use most. Shut doors and focus heat where people actually spend time.
Don’t block airflow. Furniture, curtains, or drying racks too close to the unit can reduce performance.
Remember: cold houses take time. On the first very cold day, it may take longer to feel warm—especially in poorly insulated homes.
Filters: the most overlooked winter performance issue
Dirty filters restrict airflow. Less airflow means less heat delivered to the room, and the system has to work harder to get the same result. If your heat pump feels weaker than last winter, filter condition is one of the first things to check.
When it’s time to organise a service or electrical check
It’s noisier than usual, or performance has dropped noticeably
It trips power or causes flickering when it starts
You’re getting inconsistent heating room-to-room
The outdoor unit area is frequently obstructed or exposed to heavy weather
