Do Heat Pumps need maintenance? 

In theory, Heat Pumps do not require much maintenance, and a simple DIY service is sufficient. If you clean your filters regularly, and air can flow through the coils (radiator), and nothing is blocking your outdoor unit, your Heat Pump should be running fine. If you think something could be wrong with your unit, check out our troubleshooting guide. [click here]


How often should you service your Heat Pump?

Cleaning your filters should be completed every 2-4 months. The large time range is used because every home has and every room has a different amount of filter-blocking dust. When you have a new Heat Pump installed, I recommend that you check the filter every month and clean the filter when it looks a little blocked.

Clean Your Filters/Check the Coil

The single biggest cause of poor Heat Pump performance is blocked or clogged filters. It's an easy task. In most cases, just extract the filters and clean them under a tap or vacuum and wipe them with a damp cloth. Your heat pump will be more effective and use less power if it doesn't have to struggle with dirty filters. Check your coils for grease and dust buildup.


Clean the Outdoor Unit's Coil

To help extend the life and performance of your Heat Pump, give the outdoor unit's finned coil a spray with a hose to remove any dirt and salt spray buildup. Remove any dead leaves, cobwebs, or other debris that could obstruct air flow or the drain holes in the base of the unit. This should be completed on a regular basis, e.g. annually or more frequently if you live close to the sea.


Remove obstructions from the outdoor unit. Make sure there is always a clear pathway for air to enter from the rear, and exit the front of the outdoor unit. This will help ensure maximum efficiency of your heat pump.


Heat Pump Service Checklist

  • Remove and clean filters and check the coil, 2-12 weeks 
  • Outdoor unit is not obstructed (prune plants), 6-12 months 
  • Hose down the outdoor unit and coil, 6-12 months
