Monsoon AC Maintenance Tips for Homes in Kerala

[Jasna]

Kerala’s monsoon season brings cooler temperatures, but it also comes with high humidity, moisture buildup, and occasional power fluctuations—all of which can affect your air conditioner’s performance. Whether you’ve recently had an AC installation in Calicut or have been using your unit for years, giving your AC some seasonal attention during the rainy months is essential to keep it running efficiently and safely.

1. Clean or Replace Air Filters
The monsoon raises the levels of moisture and mold in the air, which may clog your AC filters more quickly than normal. Washing or replacing your filters every 2–3 weeks during the monsoon ensures improved airflow and cleaner indoor air.

2. Shield Outdoor Units from Moisture
Rainwater and water can harm the outdoor condenser unit. Ensure it is placed on an elevated platform and cover it with a protective but airy cover to avoid water accumulation. Refrain from sealing it tightly, as this will entrap humidity and lead to rust.

3. Monitor Electrical Components
Regular thunderstorms and voltage fluctuations can damage your AC's electrical system. It's a good idea to install a voltage stabilizer or surge protector to protect your unit from sudden power spikes and dips.

4. Inspect for Mold and Bad Odors
The moist monsoon climate has the potential to create mold development within the ducts or cooling coils, which produces a damp odor. Indoor unit and coil cleaning regularly prevents this and maintains indoor air quality.

5. Get a Pre-Monsoon Service
If your AC has not been serviced for a while, monsoon is the ideal time to have a professional call by. Regular servicing guarantees all parts are cleaned, running efficiently, and safe for use throughout and after the rainy season.

Thanks for the tips! One thing I’m curious about, when you suggest shielding the outdoor unit from moisture, how effective will that really be in preventing damage? If the unit is still exposed to high humidity and rain in the air, won’t the internal components still be affected? I wonder if a cover can really make that much of a difference if the environment itself is so humid.

You’re right that the cover won’t completely protect the unit from humidity and rain in the air. The goal of the cover is really to prevent direct water accumulation on the outdoor unit, which can cause rust or other damage over time. While the humidity will still affect the internal components, a cover can reduce the amount of water exposure, helping to prolong the lifespan of the unit. It’s definitely not a foolproof solution, but it helps minimize some of the risk. Regular servicing and cleaning are also key to keeping things in good shape, especially in such a humid environment.

I get that the cover might help with direct water exposure, but isn’t the issue more about the long-term effects of constant high humidity on the internal components? Even with the cover, isn’t the moisture in the air enough to still lead to corrosion or other issues over time? I’m wondering if it’s really worth the effort if the environment itself is so humid. Thoughts on whether a cover can really make a significant difference in preventing damage in the long run?

You’re absolutely right that high humidity is still going to be present no matter what, and a cover isn’t going to block moisture in the air from reaching the unit. But the main purpose of the cover isn’t to eliminate humidity. It’s to reduce direct exposure to rain and water pooling, which can cause faster rusting and physical damage to the outer parts.

Humidity does affect internal components over time, but the cover helps slow down that process by minimizing how much water actually settles on or gets inside the unit. It’s not a perfect solution, but it adds a layer of protection, especially when paired with regular maintenance. In the long run, it can help extend the lifespan of the unit and reduce issues like corrosion. So while it won’t solve everything, it’s still worth the effort.

Thanks for the explanation! I’m curious, are there any other effective methods or products you’d recommend to prevent humidity buildup in the AC?

One simple method is making sure there’s enough clearance around the outdoor unit for proper airflow, since good ventilation helps moisture dry out faster and reduces the chance of corrosion. Some people also raise the unit slightly with a concrete pad or blocks to keep it off wet ground and avoid water pooling underneath. Another thing worth considering is applying a corrosion-resistant spray to the coils or exposed metal parts. It won’t eliminate humidity, but it can help slow down rusting over time. And if your area gets a lot of rain, installing a small awning or shield above the unit can help limit direct water exposure without trapping humidity the way a full cover might. All these little steps together can help extend the life of the unit, even if you can’t completely get rid of the moisture in the air.
