Why Deep Aircon Cleaning Prevents Mold and Humidity Damage During The Rainy Season

It’s the rainy season again. The laundry won’t dry, the walls feel sticky, and the whole house smells a little “amoy-lumang-damit.” So you switch on the aircon to get some relief. Then comes a musty smell from the vent, and you wonder if the unit is making things worse.

You’re not the only one. Filipino homeowners often ask online how often they should clean a split-type inverter aircon (or other types of aircon), whether the service fee is reasonable, and if they can skip a cleaning to save money. This guide answers those questions.

Why Rainy Months Are Hard on Your Aircon

Your aircon removes moisture from the air as it cools. When humidity is high, it removes much more. Dust and dirt on the filters and coils hold on to that moisture. A dark, damp space inside the unit is where mold grows.

Signs It’s Time for a Deep Clean

• A musty smell when you turn it on
• Weak airflow, even at your lowest setting
• Water dripping from the indoor unit onto the wall or floor
• Family members sneezing more in the bedroom
• A higher electric bill with no change even though you reduced the unit’s usage time

What Deep Cleaning Does

It removes mold where it starts. Rinsing the filter at home helps, but it can’t reach the coils, drain pan, or blower wheel. A trained technician cleans these parts during a deep clean.

It prevents leaks. A clogged drain line can leave stains on your ceiling or warp your cabinets. The repair then costs far more than the cleaning would have.

It protects your family’s sleep. A clean unit blows cleaner air. That matters most in bedrooms, where the aircon may run through the night.

It helps your bill. Clean coils cool more efficiently, so the unit doesn’t have to work as hard.

“Is Cleaning Really Worth the Fee?”

Many homeowners hesitate because the service fees can seem high, and prices vary by unit size and location. But a regular clean costs less than repairing a leak, replacing failed aircon parts, or fixing water-damaged furnishings. It also gives you better cooling for the money you already spend on electricity.

Easy Aircon Cleaning Habits

• Rinse the filters every two to four weeks.
• Change the mode to Fan or Dry for a few minutes before turning the unit off.
• Keep windows and doors closed while the aircon is on.
• Schedule a deep clean before the rainy season, and at least once or twice a year.

Stay Comfortable All Season
