5 Simple Tips for Ductless Maintenance and Troubleshooting in Palm Beach

Ductless mini splits are designed with advanced technologies and compact components to serve practically any air conditioning needs. Like any machine, mini splits need regular ductless maintenance and troubleshooting from time to time.

Ductless Maintenance and Troubleshooting

Ductless mini splits operate by the same refrigeration principles as central systems and require similar maintenance. The two elements to focus on are free airflow and component cleanliness.

Air-Handling Cabinet

Wipe down the cabinet once a month to remove dust, or vacuum the cabinet with a brush extension. Mini splits typically include a permanent air filter that may last up to eight years if well cared for. Hand wash the filter as needed and let it air dry before reinserting.

Evaporator Coil

Cold refrigerant inside the evaporator coil extracts heat from the room. This produces a substantial amount of condensate as water vapor comes into contact with the cold coil. This also means that dust and dirt stick to the evaporator like a magnet. Use a soft cloth to wipe the evaporator clean, or use a foaming disinfectant cleaner, which helps prevent mold.

Condensate Pan

Check the condensate pan for mold and algae. Pour a cup of a 50/50 bleach and water solution into the pan to kill and prevent the development of micro-organisms.

Compressor/Condenser

The outside cabinet houses the compressor and condenser. These components need to remain clean to promote efficient cooling and heating, and to prevent the compressor from overheating. Turn off the power to the mini split and wash the cabinet with a garden hose once a month. Keep an eye on the cabinet for airflow obstructions, such as tall weeds and strewn leaves and debris. Make sure there is at least three feet of clearance around the sides.

Troubleshooting

Unusual noises are sure signs of trouble. If you hear grinding or squealing from the air handler or outside cabinet, turn off the system and call your HVAC tech. If the hand-held remote stops working, look for a reset button near the bottom. You may also try fresh batteries.
