DIY AC Cleaning Warnings: What Thane Homeowners Often Do Wrong

With dozens of DIY videos on YouTube, many homeowners in Pokhran Road No. 1 & 2, Kolshet Road, and Vartak Nagar are attempting to clean their indoor AC units themselves. While washing filters is highly recommended, trying to deep clean coils and blower wheels without professional equipment can lead to expensive repairs.

1. Damaging the Delicate Aluminum Fins

Indoor and outdoor cooling coils are covered in ultra-thin aluminum fins. Wiping them with hard brushes or using excessive water pressure bends the fins, blocking airflow and causing the coil to freeze. Once bent, restoring them requires specialized comb tools.

2. Short-Circuiting the PCB Control Board

Modern split AC units contain sensitive electronic Printed Circuit Boards (PCBs) located on the right side of the indoor blower. If water splashes onto the PCB during a DIY wash, it can fry the microcontroller, resulting in a ₹3,500 replacement bill.

3. Clogging the Condensate Drain Tray

Brushing dirt off the coils often pushes debris into the narrow drain outlet. When the AC runs, condensed water accumulates in the tray but cannot drain, leading to water dripping down your living room wall.
