Here are five signs that your heat pump may be due for a service:
1. Reduced Heating Performance
If your heat pump is running but your home isn't getting as warm as it used to, dirty filters, blocked coils, or refrigerant issues may be affecting its performance. A professional service can identify the cause and restore efficiency.
2. Unusual Noises
Heat pumps should operate relatively quietly. Grinding, rattling, buzzing, or squealing noises can indicate worn components, loose parts, or fan motor issues that should be addressed before they become major repairs.
3. Higher Power Bills
A heat pump that is struggling to operate efficiently often uses more electricity to achieve the same result. If you've noticed a sudden increase in power consumption, a service could help bring operating costs back down.
4. Unpleasant Odours
Musty smells can indicate mould or bacteria build-up within the indoor unit. Regular cleaning and servicing help maintain healthy indoor air quality and eliminate unwanted odours.
5. Water Leaks
Water leaking from your indoor unit is usually a sign of a blocked drain or drainage issue. Left unattended, leaks can cause damage to walls, ceilings, and flooring.
Why Regular Servicing Matters
Regular maintenance helps:
- Improve energy efficiency
- Extend the life of your system
- Reduce the risk of breakdowns
- Maintain healthy indoor air quality
- Protect your manufacturer's warranty
