What You Can Do Yourself

Clean the Indoor Unit Filters (Monthly)

Mini split indoor units have washable filters behind the front panel. Slide them out, rinse with warm water, let them dry completely, and reinstall. Dirty filters reduce airflow and efficiency — this is the most important maintenance task you can do yourself.

Keep the Outdoor Unit Clear

Make sure the outdoor unit has at least 12 inches of clearance on all sides. Remove leaves, debris, and snow buildup. Don't stack anything against it.

Check the Condensate Drain

The indoor unit produces condensate (water) during cooling. Make sure the drain line isn't blocked. If you see water dripping from the indoor unit, the drain may be clogged.

Annual Professional Service

Once a year, have a technician inspect the system. A professional tune-up includes checking refrigerant charge, cleaning the evaporator and condenser coils, inspecting electrical connections, and verifying the condensate drain is clear.

Signs Something Is Wrong

• Reduced heating or cooling output
• Ice on the indoor or outdoor unit
• Unusual noises (grinding, squealing, rattling)
• Water dripping from the indoor unit
• The system won't turn on or respond to the remote

Any of these warrant a service call.
