Heat pump servicing is often overlooked by many home-owners. People purchase and install units and do nothing beyond that to maintain their asset and are often surprised and dismayed if the unit has problems further down the track.

Don’t fall into the trap of purchasing equipment and never having it serviced, as by servicing your heat pump you will extend its operating life and maintain efficiency.

At Heat and Cool, we are Mitsubishi Electric heat pump specialists, servicing the Auckland area. Through product and operating knowledge we recommend that residential pumps be serviced annually and commercial units serviced at either six or three month intervals, dependent on usage.

Why service your heat pump?

Heat pump servicing is often overlooked as an integral part of maintaining the longevity and efficiency of a heat pump unit. We see heat pump servicing as being of similar importance to the servicing of your car, it keeps it performing well and increases the life of the unit.

Heat pumps are all about efficiency and by maintaining efficiency it keeps running costs low.

So it makes sense that servicing and maintenance will retain efficiency and because heat pumps are an investment, it pays in the long term and protects your investment. With the average life of a reputable unit like Mitsubishi Electric lasting around 10-15 years, proper servicing of the unit will help it operate efficiently throughout its full life cycle.

Our servicing of your heat pump unit would include:

  • Cleaning of filters, vanes, grills and outer covers (internal and external)
  • Checking fan blades or scrolls and clean as required
  • Checking condensate line and test for drainage
  • Checking voltage, current draw and all electrical wiring including terminals
  • Checking and testing start/stop sequence and heating/cooling changeover
  • Checking both indoor and outdoor units ensuring they are level; mounts are intact and checking for unusual sounds or vibrations
  • Leak testing around flare fittings
  • Checking both evaporator and condenser coils and report if cleaning is required
  • Test run and check air on and air off temperatures

Without regular heat pump servicing your heat pump or air conditioning unit could harbour dust, allergens, mould and mildew.

Aside from being unsightly, these conditions can lead to the poor running of your unit and more alarmingly, affect your family’s health and well being.

When should I have my heat pump serviced?

In Auckland, we are somewhat blessed with moderate temperatures year round. So in terms of heat pump servicing, it is best to have your unit serviced before you really need to. If you like to pump the cool air on those humid Auckland days and nights or increase the temperature on chilly winter days and nights, then a service in either Spring or Autumn is ideal.

With residential units we recommend an annual service, however there may be instances when your unit needs some additional TLC:  any instances where you are experiencing higher power bills, or if the unit is not adequately heating or cooling, or is not operating at previous levels, or if the unit is emitting odd smells from either the internal or external unit.
