How often should you clean your heat pump in Halifax?
The short answer is at least once a year. The long answer depends on your home, your system, and how you use it.
What the manufacturers say
Every major heat pump manufacturer, Mitsubishi, Daikin, Fujitsu, LG, Carrier, recommends annual professional cleaning as part of standard maintenance. Skip it, and you can void your warranty. That's usually buried in the fine print of the owner's manual, but it's there.
Annual cleaning also keeps your system operating near its rated efficiency. A dirty coil or blocked fan can quietly cut performance by 10 to 25%, which shows up on your power bill long before it shows up as a breakdown.

When once a year isn't enough
A few situations push the cleaning schedule tighter than annual. If you have pets, the fur and dander pull into the coil faster than you'd expect. If anyone in the household has allergies or asthma, cleaner coils mean cleaner air. If your system runs year-round, which most Halifax homes do, between heating in the winter and dehumidifying in the summer, the total hours add up.
In those cases, twice a year keeps things ahead of the problem. We see it most often with multi-pet households and homes near the harbour, where salt air accelerates corrosion and biofilm growth.
Signs you're overdue
Heat pumps tell you when they're unhappy. Musty smells when the blower kicks on, visible dust or mould on the fins, reduced airflow, higher running costs, or a hum that's louder than you remember. Any one of these is a nudge to book a clean.
The other tell is simpler: if you can't remember the last professional service, it's time.
Common questions
- Will cleaning my heat pump more than once a year damage it?
- No. The cleaning process is non-invasive. We disassemble, wash with eco-friendly solutions, and reassemble. You can safely clean a system every 6 months with zero risk to the components.
- How long does an annual deep clean take?
- About 1 to 1.5 hours per indoor head for ductless, 2 to 3 hours for ducted systems, and 30 to 60 minutes for HRV/ERV units. We never rush. Thoroughness matters more than speed.
- Does rinsing the filter count as cleaning?
- It helps, but it's not the same. Filter rinsing catches about 20% of the buildup. The rest is on the coil, fan barrel, and drain pan. Parts you can't reach without disassembly.
