The life expectancy of a heat pump depends on several factors, such as the type of heat pump, the location of the heat pump in your home and the level of maintenance. Heat pumps typically last an average of 15 years, although if not cared for properly, it can be closer to 10 years or less – quite a difference. A heat pump heats and cools a house by transferring heat from one source to another. In warm weather, it transfers heat from the inside to the outside and in cold weather, it reverses this system.

Weather conditions where you live can affect heat pump longevity. The more extreme the seasons, the harder your heat pumps will have to work over the years. Fortunately, Auckland doesn’t have the coldest winter conditions which reduce the chance of ice occurring. The size of the unit is another contributing factor. An undersized unit for a large house will be forced to work harder to warm or cool down a room. Choosing an appropriate unit will not have to use up all of its power to give you the required cooling or heating. It will cool and warm the room faster and be able to maintain your chosen temperature with more ease.

For size, the best way to fix this would be to replace the unit with a more appropriate-sized one if you can afford it. Not only will it be easier to maintain, but it will also be more efficient. Better yet, when planning to get an HVAC unit, consider the size of the unit compared to the room.

The most important factor in determining the life of your heat pump is maintenance. There are several steps you can take to make sure your heat pump is in good condition, which will help extend its lifespan. Ice can build up on the outer coil, causing frost and hindering the pump’s ability to provide heat. The outdoor condenser unit fins must be regularly cleaned or replaced too. Heat pumps are more efficient than air conditioners because they kill two birds with one stone in heating and cooling your home with one product. Here are some other ways to prolong the life of your unit.

  1. Conserve energy by closing doors and windows when the heat pump is turned on to keep the temperature even.
  2. Fix, don’t replace. Experienced heat pump specialists are experts at fixing any issues and offering maintenance plans to keep your unit running smoothly.
  3. Make sure the thermostat is calibrated to a heat pump properly to avoid unnecessary work because the temperatures don’t match.
  4. Check the unit’s refrigerant ducts for leaks. Leaks in the ducts will cause the unit to work harder affecting its performance and, subsequently, its lifespan.
