Across Southland, heat pumps are the go-to solution for year-round indoor comfort. From homes in Invercargill to commercial sites across the region, these systems deliver reliable heating in winter and cooling in summer—all while using far less energy than traditional systems.
But there’s a catch.
Even the best heat pump won’t perform well if it’s clogged with dust, dirt, and mould. Over time, without proper cleaning, your unit becomes less efficient, more expensive to run, and a potential source of poor air quality. Regular heat pump cleaning isn’t just a maintenance task—it’s a critical part of keeping your home or business healthy, efficient, and warm.
In this guide, we’ll explore why cleaning matters, what’s involved in a professional service, and how Southlanders can benefit from making this a regular part of property upkeep.
Why Heat Pump Cleaning Matters in Southland
Southland’s environment poses some unique challenges for heat pump systems. Heat pumps often work harder- and longer- with frequent rainfall, damp winters, and long heating seasons than in other parts of New Zealand. This high usage leads to faster buildup of:
- Dust and allergens in filters
- Mould spores in internal components
- Moisture inside coils and drainage trays
Left unchecked, these issues affect not only performance but also health. A heat pump that hasn’t been cleaned can circulate contaminants, trigger allergies, or worsen damp conditions.
Common local factors include:
- High humidity and condensation in the winter months
- Indoor wood burning or pet dander in rural homes
- Farming and commercial settings with higher dust loads
These conditions make regular cleaning essential for Southland households and businesses relying on consistent indoor comfort.
What’s Included in a Professional Heat Pump Cleaning?
Many people assume that a heat pump clean means just rinsing the filters. But a professional clean goes far beyond that—and it’s the only way to get your unit operating like new.
At SHV, a standard heat pump cleaning service includes:
- Removal and washing of filters
- Disinfection of the coil, fan, and internal housing
- Drain inspection and flushing to prevent mould and clogs
- Cleaning of external housing and vents
- System check to ensure optimal airflow and temperature settings
Frequency matters:
- Every 6–12 months for homes used year-round
- Every 3–6 months for businesses or multi-unit dwellings
- More frequently in households with smokers, pets, or allergy sufferers
While DIY filter cleaning is helpful between services, it does not replace the need for a complete system cleaning by trained technicians. Without professional equipment and knowledge, deep components remain dirty and inefficient.
Impact on Performance, Efficiency, and Power Bills
A clean heat pump performs better. It’s that simple.
When your filters and internal coils are free of dust and grime, your unit doesn’t have to work as hard to heat or cool the air. That translates directly into faster temperature control, smoother operation, and less energy use.
Real-world benefits include:
- Lower electricity bills due to improved airflow and reduced strain
- Fewer maintenance issues, like frozen coils or poor heating output
- Quieter operation with smoother fan and motor performance
- Extended lifespan of the unit and its components
Even just a 10–20% drop in airflow due to dirty components can raise energy usage significantly. Over time, the cost of not cleaning can far outweigh the cost of a professional service.
Health and Air Quality Benefits of a Clean System
For families and business owners alike, indoor air quality matters more than ever. Your heat pump is responsible for temperature, and what’s floating in the air you breathe.
A dirty heat pump can:
- Circulate dust, pollen, and mould spores
- Worsened asthma or allergy symptoms
- Contribute to dampness and odour in enclosed spaces
In homes with children, elderly residents, or anyone with respiratory conditions, clean air is a non-negotiable. And in commercial environments—like schools, offices, or aged care facilities—keeping systems hygienic isn’t just best practice; it’s a health and safety issue.
Regular heat pump cleaning helps remove hidden contaminants that filters alone can’t trap. It’s a simple way to ensure better health, comfort, and peace of mind.
Choosing a Reliable Cleaning Service in Southland
While heat pumps are relatively low-maintenance, they’re also highly technical systems. That means not just anyone should be servicing them.

- Experience with all major brands and models

In Southland, there are also heat pump grants available to eligible households. These initiatives aim to support healthier homes by helping cover the cost of heat pump installation or upgrades, especially when replacing inefficient or unhealthy heating systems.
Keeping your system clean supports grant goals by:
