How to Maintain & Deep Clean Your Split Air Conditioner for Peak Efficiency

Why Regular AC Maintenance is Crucial

A poorly maintained air conditioner consumes up to 25% more electricity and loses cooling efficiency rapidly due to clogged cooling coils and restricted airflow. Additionally, stagnant moisture in drain pans becomes a breeding ground for black mold and bacteria.

Step 1: Cleaning the Air Filters Bi-Weekly

The nylon mesh air filters behind your indoor front panel should be rinsed under lukewarm water every 15 days during peak summer months. Never dry them in direct sun, as extreme heat can warp the plastic framework.

Step 2: Evaporator Coil Jet Foam Cleaning

Dirt baked into the aluminum evaporator fins cannot be removed by simple dusting. Using pH-neutral foaming coil cleaner combined with low-pressure water jet washing clears microscopic dust and deodorizes the blower fan.

Step 3: Checking Refrigerant Pressure & Compressor Health

If your AC takes longer than 15 minutes to drop room temperature, you may have low gas pressure due to microscopic flare-nut leaks. Certified technicians measure suction pressure using dual-manifold gauges to ensure exact OEM PSI specifications.

When to Call a NanhiCare Professional

Whenever you hear bearing squeaks from the outdoor blower, notice ice forming along the copper suction line, or smell burning odors from the electrical terminal, power off the unit and schedule a professional inspection.
