My heat pump is turned on but not working properly.

If your indoor unit is showing a flashing green light, this usually indicates a fault condition. Other heat pump brands may display faults differently. Please contact our office on 03 578 0030 and our team will help diagnose the issue.

Why does my heat pump stop heating occasionally when it's frosty?

This is normal. When operating in heating mode during cold weather, heat pumps periodically enter a defrost cycle to remove ice from the outdoor unit. During this time, the indoor unit may temporarily stop producing warm air for up to 10 minutes.

You may notice:

Water draining from the outdoor unit
Steam rising from the outdoor unit
Swishing or gurgling sounds

These are all signs your heat pump is operating normally.

There is water dripping from my outdoor unit. Is this normal?

Yes. Heat pumps naturally produce condensation during normal operation. Water may drip from the outdoor unit during both heating and cooling modes.

However, water dripping from the indoor unit is not normal and should be investigated. If water is leaking inside your home, please contact our office on 03 578 0030.

How often should I clean my heat pump filters?

We recommend checking and cleaning your filters every 4–8 weeks, depending on how frequently the system is used. Homes with pets, wood burners, construction work nearby or higher dust levels may require more frequent cleaning.

Regular filter cleaning helps maintain:

Heating and cooling performance
Energy efficiency
Indoor air quality
System lifespan

How do I clean my heat pump filters?

Most Daikin filters can be removed by opening the front panel of the indoor unit.

Simply:

Remove the filters.
Vacuum away dust and debris.
Wash with lukewarm water and mild detergent if required.
Allow filters to dry completely before reinstalling.

How can I maintain my heat pump to help it run efficiently?

To help keep your heat pump running efficiently:

Clean indoor air filters every 4–8 weeks.
Wipe indoor grilles and louvers with a damp cloth.

Trim vegetation away from the outdoor unit.

We recommend a professional service every 1–2 years to maintain efficiency, maximise system life and help meet manufacturer warranty requirements.

Hot Water Heat Pump FAQs

What is a hot water heat pump?

A hot water heat pump uses energy from the surrounding air to heat your water. Because it transfers heat rather than creating it directly, it is significantly more energy efficient than a traditional electric hot water cylinder.

Are hot water heat pumps cheaper to run than electric hot water cylinders?

Yes. Hot water heat pumps can use up to 70–80% less electricity than a conventional electric hot water cylinder, helping reduce household power bills while still providing reliable hot water.

How much can I save on my power bill?

Savings vary depending on your household size and hot water usage. As hot water can account for around 25–35% of a home's energy use, a hot water heat pump can make a noticeable difference to your electricity costs.

Can a hot water heat pump supply enough hot water for my family?

Yes. Hot water heat pumps are available in a range of sizes to suit everything from smaller households through to large families with high hot water demand. We can recommend the right system based on your household's needs.

Are hot water heat pumps suitable for existing homes and new builds?

Absolutely. Hot water heat pumps are suitable for both new homes and upgrades to existing hot water systems. Our team can assess your property and recommend the best solution for your home and budget.

Ventilation Questions

What are the different types of ventilation systems?

There are several ventilation options available, including positive pressure, balanced pressure and heat recovery systems. The best solution depends on your home's design, insulation levels and moisture concerns.

Do I need a ventilation system if I already have a heat pump?

A heat pump controls temperature, while a ventilation system manages moisture and air quality. Many homes benefit from having both systems working together.

Will a ventilation system reduce condensation?

In many cases, yes. Ventilation systems help remove excess moisture from the home, reducing condensation and helping prevent mould growth.

How do I know if my home would benefit from ventilation?

Signs your home may benefit from ventilation include:

Condensation on windows
Mould or mildew
Damp or musty smells
Allergy or asthma concerns
Rooms that feel stale or stuffy

If you're experiencing any of these issues, our team can help recommend the most suitable ventilation solution for your home.

Are ventilation systems noisy?

No. Modern ventilation systems are designed to operate quietly and unobtrusively, providing continuous fresh air circulation without disrupting daily life.

How often does a ventilation system need servicing?

We recommend servicing your ventilation system every 2–3 years and replacing filters as recommended by the manufacturer to ensure optimal performance and air quality.
