How to Maintain Mini Split Heat Pumps How to Maintain Mini Split Heat Pumps
Mini split heat pumps are one of the most efficient ways to air condition your home. The pump consists of a two unit ductless heat, air conditioning and ventilation system. One unit is located outdoors while another unit is installed inside. Copper piping connects the two units. A coil in the outdoor unit serves as a heat exchanger and compressor. The indoor unit contains a coil and a fan. The fan distributes air throughout the home. Several air handlers or “heads” are attached in various places in the house. The pump distributes refrigerant to the various air handlers. It is vital that you maintain your pump well for higher efficiency, but this isn’t difficult to accomplish.
Step 1 – Clean the Housing
Turn off the power supply before you clean the pump. Use a soft brush to clear dirt and debris from the air outlet grills. Mix some mild detergent and warm water in a basin. Dip a soft cloth into the water. Wring the cloth to remove most of the water. Wipe the exterior surface of the heat pump with the cloth. Rinse the cloth several times as you wipe to prevent dirt residue on the pump panels.
Step 2 – Remove the Filters
Check the arrows on the surface panel for directions on how to remove them. Take down the panel and clean it. Check the air filters for a tab which allows you to remove the filters. Hold the tab and carefully pull out the filters as guided by the arrows.
Step 3 – Clean the Filters
Remove the dust and debris from the filters with the help of a vacuum brush attachment. Wash the filters in warm water with a bit of mild detergent. Use a soft-bristled brush to clean the filters thoroughly. Rinse the filters and place them in a cool, secure place to dry completely. Avoid hot water when you clean your mini split heat pump as it could cause discoloration. It is best to clean your filters every 3 months. However, if you live in a dusty region you’re better off if you clean them more frequently.
Step 4 – Check the Vents and Condenser
Carefully examine the air outlet and intake vents. Sometimes dirt and debris may collect in the outlet. This hampers proper air flow. Use a putty knife to remove obstructions from the outlet and vents. Locate the condenser within the pump. Check to confirm that it is properly mounted. Make adjustments if necessary.
Step 5 - Re-install the Filters
Retrieve your clean filters. Slide the filters into their slot as guided by the arrows. Re-install the panel. Restore the power to your mini heat pump. It should give you regular service.
Step 6 – Take Protective Measures
Do not splash water onto your mini heat pump as it can cause the unit to malfunction. Always ensure that there are no obstructions at the air outlet and intake vents. Obstructions hamper the unit’s efficiency. If you notice that your unit isn’t properly grounded, make the necessary adjustments.
