Heat pumps are one of the most efficient ways to heat and cool your home, but they rely on regular maintenance to stay that way. One of the simplest – and most important – tasks you can do yourself is cleaning the filter. If you’ve been wondering how to clean a heat pump filter, this step-by-step guide will help you get it done quickly, safely, and effectively.

Why Filter Cleaning Matters

A clean filter helps your heat pump run more efficiently and keeps your indoor air healthy. Over time, dust, pollen, pet hair, and other particles build up on the filter. If left unchecked, this can lead to:

  • Reduced airflow and efficiency
  • Increased energy bills
  • Unpleasant smells
  • Strain on your unit’s fan motor
  • Poor air quality in your home

Keeping your filter clean can extend the life of your system and ensure your heat pump continues to deliver cost-effective comfort all year round.

How Often Should You Clean It?

As a general rule, filters should be checked and cleaned 3 months, depending on use. If you have pets, allergies, or live in a dusty area, monthly cleaning may be best. 

Regular cleaning helps keep your unit running smoothly between professional maintenance checks. For a full-service clean, check out our maintenance services.

Step-by-Step Guide to Cleaning Your Filter

Cleaning your heat pump filter is simple and doesn’t require any special tools. Here’s how to do it:

  1. Turn off the unit: Always switch off your heat pump before cleaning.
  2. Open the front panel: Gently lift the cover of your indoor unit. On most wall-mounted models, the panel will hinge open easily.
  3. Remove the filters: Carefully slide out the mesh filters. They’re usually located just behind the front panel.
  4. Vacuum the filters: Use a vacuum cleaner with a soft brush attachment to remove dust and debris.
  5. Wash if needed: If the filters are particularly dirty, rinse them gently with lukewarm water. Avoid using hot water, soap, or harsh chemicals.
  6. Dry completely: Let the filters air dry completely before reinserting them. Never reinstall a damp filter.
  7. Reinstall and close: Slide the clean, dry filters back into place and close the panel securely.

That’s it – your heat pump is ready to go again.
