Heat Pump Lifespan: How to Make Your System Last for Decades

For many Kiwi homes, the heat pump is a year-round lifesaver—keeping us warm in winter and cool in summer, all while keeping those power bills manageable. But just how long can you count on your trusty heat pump? A well-cared-for unit can last well over a decade, yet many people unknowingly cut their system’s life short by skipping a few key maintenance steps.

Today, Fonko is diving into everything you need to know about getting the most out of your heat pump. From easy DIY care to knowing when to call in the pros, we’ll explore the tips and tricks that can help your system keep running smoothly for years—maybe even decades! Whether you’re new to heat pumps or just want to make sure yours is around for the long haul, read on to learn how a little extra care now can save you plenty later!

 

How Long Do Heat Pumps Really Last?

Typically, a well-maintained heat pump can last between 10 to 15 years, with some units even reaching 20 years under ideal conditions. However, climate, usage, and maintenance all play significant roles in how long your heat pump will continue to perform efficiently. Coastal homes in areas with salty air, for instance, might find that external wear and tear on the unit could reduce its lifespan. Similarly, homes that rely on their heat pump for constant temperature control year-round might see a faster decline if maintenance isn’t prioritised.

In New Zealand, where we tend to use heat pumps primarily for winter warmth, it’s important to be mindful of the way we run and care for these units. Even minor adjustments, like keeping temperatures steady rather than constantly adjusting them, can make a difference. Opting for a heat pump model designed to withstand New Zealand’s specific climate conditions can also have an impact, it goes without saying that investing in a system that’s tailored for local environments is key to longevity.

 

The Maintainance Basics 

You wouldn’t skip an oil change for your car or let your home’s gutters clog up, so why not give your heat pump the same attention? Here are the top three ways to keep your heat pump running smoothly and efficiently for the long haul.

 

Step 1: Clean or Replace Indoor Filters Every 3 Months

  • Why: Clean filters allow your heat pump to “breathe” easily, improving efficiency and preventing wear on the system.
  • How: Locate the filter inside the indoor unit (consult your manual for exact placement). Remove and either vacuum it or rinse it under lukewarm water. Allow it to dry completely before placing it back. 
  • Tip: If you have pets or allergies, aim to clean or replace filters more frequently.

 

Step 2: Deep Clean the Coils Yearly 

  • Why: Dirty coils can prevent your heat pump from absorbing and releasing heat effectively, which overworks the unit.
  • How: Power off your unit. Gently wipe the coils using a soft brush or cloth. You can also use a vacuum with a brush attachment for tougher dirt. If grime persists, consider a mild detergent but avoid abrasive cleaners as they can damage the coils.

 

Step 3: Clear Debris from the Outdoor Unit Regularly

  • Why: Debris, leaves, and dirt can clog the outdoor unit, restricting airflow and making the system work harder.
  • How: Check the area around the outdoor unit every couple of weeks, especially after storms. Clear away any leaves, twigs, or dirt buildup as needed. Trim any overgrown plants around the unit to ensure it has a clear space of at least a meter for optimal airflow

 

Spot the Warning Signs Early (and Save on Repairs)

One of the best ways to extend your heat pump’s lifespan beyond the basics is to catch problems early before they become expensive repairs. Thankfully, heat pumps have their ways of letting you know when they need some attention—you just have to know what to look for.

Some common red flags include:

  • Strange Noises: If your heat pump is making loud or unusual sounds, it could be a sign of loose parts or a motor problem.
  • Weak Airflow: If the air coming out feels weaker than usual, something may be blocking the system or a motor could be wearing down.
  • Unusual Smells: Musty or burning smells aren’t just unpleasant—they can indicate mould in the filters or electrical issues that need immediate attention.
  • Inconsistent Temperatures: If your heat pump is struggling to keep your space warm or cool, there could be an issue with the compressor or refrigerant levels.

These issues are best handled by a professional, so don’t hesitate to call one if you notice any of these warning signs. Catching a small problem early can save you from a bigger, costlier repair down the line—and help extend your heat pump’s life.
