Do I have to professionally service my heat pump?
Heat pumps, like any other appliance, need to be regularly maintained to ensure their longevity. MHI recommends that you professionally service your heat pump annually.
How can I ensure that my heat pump is properly maintained to operate efficiently all year around?
To ensure your heat pump works all year round you should regularly check, or have a technician check, for any blockages or obstructions in the drain pipes that run from your outdoor unit, clean the filters and ensure your heat pump is regularly serviced.
How do I clean the filters in my heat pump and how often should I do this?
For wall-mounted systems, cleaning the filters on the indoor unit of your heat pump is usually a simple process. If you use your unit often you will need to regularly check and clean the filters. We recommend doing this at least every couple of months if your heat pump is used daily.  If you use your unit infrequently you should clean your filters at the start of the heating and cooling season. The design of the filters means they are easily washed with soap and water.
Do I need to top up refrigerant gas regularly in my heat pump?
Refrigerant re-gassing will only be needed if the outdoor unit is damaged and there is a refrigerant leak. In this event please contact us immediately.
