Maintenance for a Ductless Mini-Split System

Your ductless mini-split system works hard to keep you cool and comfortable. Like any other HVAC system, it needs consistent maintenance to function at maximum efficiency. Many maintenance steps must be completed by your qualified HVAC pro, but there are cleaning and care steps you should be doing in between service visits.

Maintaining Your Ductless System

Ductless mini splits utilize most of the same parts and components as their larger central A/C relatives — the parts are just smaller. Though mini in size, their maintenance and care are equally important. Put on your chore clothes and get started!

• Filter — The air filter on your ductless system protects parts and helps the unit operate efficiently by capturing dust and debris. If you use your ductless system daily, check the filters at least once a month. If the filters are dirty, remove them and gently wash by hand.
• Evaporator — When you remove the filters, you will see the evaporator coil. This is the component that cools your room by absorbing heat from the air. Use a vacuum brush extension to suck out the dirt from the coil.
• Vanes — To clean the dirt from the blower side, remove the horizontal vane. The vertical vanes may pivot to the side and out of the way. Use your vacuum extension again to clean the area. Use a dry cloth for the finishing touches.
• Outdoor unit — The outdoor unit of your ductless mini-split system contains essential components that need to be regularly cleaned, too. To clean the unit, use a foaming coil cleaner. Safety first — flip the circuit breaker to the ductless system, use protective eye wear and follow the foaming coil cleaner instructions carefully.

Take care of your ductless mini-split system, and it will take care of your comfort needs and save energy. If you have any questions, contact your HVAC professional.
