How Often Should I Service My Mini Split?

Modified on Wed, 2 Apr at 1:29 PM

Why Regular Maintenance Matters

Just like a car, your mini split needs routine service to stay in peak condition. Regular maintenance helps extend the lifespan of your system, improves efficiency, and helps avoid costly breakdowns — especially during extreme weather.

Recommended Service Schedule

1. Basic Maintenance (Homeowner) – Every 1 to 2 Months

Clean the air filters: Every 30–60 days (more often if you have pets, smoke, or allergies).
Wipe down the indoor unit: Keep the surface clean and dust-free.
Inspect the outdoor unit: Clear away leaves, dirt, or debris that could block airflow.

2. Professional Maintenance (HVAC Technician) – Once Per Year

Schedule a full inspection and tune-up at least once a year — ideally in the spring (before summer) or fall (before heating season).

Check refrigerant levels
Test electrical connections and controls
Clean the evaporator and condenser coils
Inspect the drain line and pan
Ensure sensors and thermostat are calibrated

Signs You May Need Service Sooner

Reduced cooling or heating performance
Strange noises or vibrations
Unusual odors from the indoor unit
Water leaks or ice build-up
Unit turns on and off frequently (short cycling)

Tip: If you notice any of the above, don’t wait for your annual checkup — submit a support ticket or call a licensed technician.
