How often should a heat pump be cleaned in Nova Scotia?
Filters are only the surface. The parts that affect airflow, smell and efficiency most — the blower wheel, evaporator coil and drain pan — sit behind the cover and need a technical cleaning on a schedule.
A practical schedule
For most Halifax homes running a heat pump year-round for both heating and cooling, a full indoor-head cleaning every 12 months keeps airflow and drainage in good shape.
- Every 12 months: single-family home, year-round use, no pets
- Every 6 to 9 months: pets, smokers, renovations, or a home near heavy traffic or salt air
- Every 6 months: rental units and short-term rentals, where use patterns are unpredictable
- Monthly: rinse or vacuum your own washable filters between professional visits
Signs your system is overdue
Systems rarely fail suddenly from dirt — they lose performance gradually, which is why the symptoms are easy to normalize.
- A musty or sour smell in the first minutes of operation
- Weaker airflow than you remember, or the fan running louder for the same output
- Water spotting or dripping below the indoor head
- Dark speckling visible on the blower wheel through the outlet louvre
- Longer run times and higher power bills for the same comfort level
What a real cleaning includes
A cleaning visit should be documented, not just performed. TrustM8 records the condition before and after work so you can see exactly what changed inside the equipment.
- Filters removed, washed and reinstalled
- Evaporator coil and blower wheel cleaned within the selected scope
- Drain pan and condensate line cleared and flow verified
- Outdoor unit cabinet and coil face inspected and cleared of debris
- Before-and-after photos in a written record
