At Napier Heat Pumps we recommend having your heat pump serviced before winter as this will be when you use it the most. Cleaning the filters, disinfect the coil, flushing out the drain tray and cleaning off mould from the interior fan area. Flushing out the outdoor coil and cleaning the paint work helps maintain the outdoor unit in the harsh Hawkes Bay environment. Service at least once a year but if you use it a lot in cooling you may want to get it done before summer as well. This will increase the lifespan of your heat pump.
