Key takeaways
- A heat pump is one of the hardest-working appliances in your home. It runs through Auckland's hot summers, damp winters and everything in between. Like any mechanical equipment, it performs best when it's maintained regularly.
- Many breakdowns that appear to happen "without warning" actually develop slowly over months or years.
- Homeowners should clean the indoor air filters every two to three months, or more often if there are pets, renovations or dusty conditions.
- Dirty filters reduce airflow, increase power consumption and can affect indoor air quality.
Clean the Filters Yourself
Homeowners should clean the indoor air filters every two to three months, or more often if there are pets, renovations or dusty conditions.
Dirty filters reduce airflow, increase power consumption and can affect indoor air quality.
Professional Servicing Every Year
For most homes, an annual professional service is recommended.
During a service, a technician will typically:
- Clean the indoor coil.
- Inspect the outdoor unit.
- Check refrigerant performance.
- Test electrical components.
- Clear the condensate drain.
- Confirm the system is operating efficiently.
This goes well beyond simply washing the filters.
Homes That Need More Frequent Servicing
Some properties benefit from servicing every six months, including:
- Homes with pets.
- Coastal properties.
- Dusty environments.
- Heavy year-round use.
- Rental properties with continuous operation.
A technician can recommend an appropriate schedule for your situation.
Why Servicing Matters
Routine servicing helps to:
- Lower electricity costs.
- Maintain heating and cooling performance.
- Improve indoor air quality.
- Reduce the likelihood of breakdowns.
- Extend the lifespan of the system.
Small maintenance issues are generally much cheaper to address than major repairs.
Signs Your Heat Pump Is Overdue
You should consider booking a service if:
- Airflow feels weaker than before.
- The unit smells musty.
- It has become noisier.
- Heating or cooling takes longer.
- It has been more than 12 months since the last professional service.
