Maximising heat pump efficiency – the importance of servicing and maintenance

As summer approaches, rising temperatures require comfortable indoor spaces for homeowners, businesses, and customers. A pleasant and invigorating environment is essential for productivity and well-being.

Regular maintenance and servicing of your heat pumps by a skilled technician is imperative to ensure that they continue to cool your environment at optimal performance throughout the warmer months. Though robust, heat pumps require professional care to maintain efficiency and extend their lifespan. Regular maintenance and servicing also allow technicians to identify potential issues before they become significant problems. Early detection of worn parts or developing faults can prevent unexpected breakdowns during the peak summer heat when repair services are in high demand and potentially more expensive.

Ideally, heat pumps should be serviced twice a year—in the Autumn before winter sets in and in the Spring to beat the summer heat. However, an annual check-up before summer is essential, at minimum, to ensure the system is ready for the increased cooling demands.

How does a heat pump work

A heat pump harnesses innovative technology to heat your home or business with remarkable efficiency. It operates similarly to a refrigerator but in reverse. During heating mode, it draws in air from the outdoor environment and brings it inside, passing it through the unit’s refrigerant gas pipes. In cooling mode, it removes heat from inside the building and releases it outside. The ingenious ability of heat pumps to reverse the refrigerant cycle and transfer heat in both directions sets them apart from traditional heating and cooling systems.

Why your heat pump needs servicing annually

One primary reason for annual heat pump maintenance and servicing is the relentless accumulation of dust and dirt, which impacts the system’s efficiency and effectiveness.

The outdoor unit, exposed to the elements, can collect leaves, pollen, and other debris. This buildup can obstruct airflow, forcing the system to work harder and consume more energy. The indoor unit’s air filter also traps dust and particles, which, if not regularly cleaned or replaced, can restrict airflow and compromise the pristine indoor air quality we all aspire to maintain.

 Another critical issue is the insidious growth of mould and bacteria, particularly in the indoor unit. The dark, moist environment created by condensation can be ideal for these microorganisms. Regular cleaning prevents the growth of mould and dust, ensuring better air circulation and a healthier indoor environment, while reducing the risk of respiratory issues for occupants.

The coils in both the indoor and outdoor units play a vital role in heat transfer. When these coils become dirty, they can’t efficiently absorb or release heat, leading to frustrating decreased performance and increased energy consumption. In severe cases, dirty coils can cause the system to freeze up, potentially leading to compressor failure – an expensive repair that could derail your quest for an energy-efficient home.

Refrigerant levels are another crucial aspect of heat pump operation. Alarmingly low refrigerant levels, often due to small leaks, can significantly impact the system’s ability to cool effectively. During a maintenance check, a skilled technician can identify and repair any leaks and ensure the refrigerant is at the optimal level, restoring your system’s peak performance.

The condensate drain line is an often-overlooked component that requires vigilant attention. This line removes the condensation produced during the cooling process. If clogged, it can lead to devastating water damage, mould growth, and system shutdown. Regular cleaning of this line prevents these issues and ensures flawless drainage, contributing to your ideal home environment.

Electrical connections and moving parts also need inspection and tightening. Loose connections can cause system failure or pose safety risks, while proper lubrication of moving parts reduces wear and tear, extending the heat pump’s life.

Be sustainable – use less energy

Heat pumps are incredibly efficient, meaning they consume less energy to produce heat than other options. In New Zealand, the average heat pump can put out three times more heat than the power they consume.

From an efficiency standpoint, a well-maintained heat pump can significantly reduce energy consumption. The difference between the energy consumption of a well-maintained heat pump and a severely neglected one ranges from 10% to 25%. This translates to lower energy bills and a reduced carbon footprint, offering a rewarding step towards your eco-friendly aspirations.

Your checklist

During a typical service visit, a technician will:

  • Clean or replace air filters.
  • Clean and inspect coils.
  • Check refrigerant levels and test for leaks.
  • Clean and clear the condensate drain.
  • Inspect and tighten electrical connections.
  • Lubricate moving parts.
  • Check and calibrate thermostat settings.
  • Inspect ductwork for leaks or damage.

Did you know?

Penguin-approved technology: Heat pumps work on the same principle as a penguin’s circulatory system, which keeps them warm in freezing Antarctic temperatures. So, you could say your heat pump is bringing a bit of penguin magic to your home!

Time-traveling warmth: Heat pumps don’t actually create heat; they just move it around. So, when you’re warming up your living room, you’re technically using heat from the past! It’s like a cosy time machine!

Stealth heating: Heat pumps are so quiet that some Kiwis have reported forgetting they’re on. It’s like having a ninja secretly warm your house.

Confused birds: Amusing anecdotes have been told of native New Zealand birds like tui and kereru being puzzled by outdoor heat pump units. In winter, these heat pump units expel warm air, and the birds have used them like peculiar warm homes. Rather than killing two birds with one stone, its heating two homes with one pump!

Workout for your house: If your home were a person, installing a heat pump would be like putting it on a fitness regime. It’s all about energy efficiency and performance!

Weather prediction skills: Some New Zealanders swear their heat pumps are better at predicting weather changes than the official forecast. When the heat pump suddenly works harder, they know a cold snap is coming!

Relationship saver: Heat pumps have been jokingly referred to as “relationship savers” in New Zealand, ending arguments over who gets up to stoke the fire or add another layer of clothing.

Sheep-counting alternative: The gentle white noise of a heat pump has been known to lull Kiwis to sleep faster than counting sheep – a betrayal to New Zealand’s woolly icons!
