Heavy rain is currently drenching most Indian cities, including Delhi‑NCR, causing a noticeable drop in temperature. While the mercury falls, atmospheric humidity often spikes, leaving many households still uncomfortable with lingering sweat. This paradox leads to a common question: should the air conditioner be switched on during the monsoon?

Monsoon Weather and Comfort

Relative humidity can soar above 80% during monsoon days. High moisture reduces the body's natural cooling mechanism—evaporation of sweat—making the indoor environment feel sticky even when temperatures are moderate. An air conditioner, especially on a dehumidifying setting, extracts moisture from the air while lowering temperature, thereby restoring comfort.

Technical Readiness of Modern AC Units

Contemporary split‑type ACs are engineered to endure a wide range of outdoor conditions, including rain. Nevertheless, prudent usage is essential. The dry mode is particularly useful in monsoon weather; it focuses on moisture removal, delivers efficient cooling, and curtails electricity consumption. Ensure the outdoor condenser has proper drainage and is not surrounded by standing water, which can impair performance and accelerate corrosion.

Power Fluctuations and Safety Risks

Monsoon seasons are notorious for erratic power supply and frequent lightning strikes. Sudden voltage drops or surges can damage compressor coils or electronic circuitry. It is advisable to connect the AC to a surge protector or an uninterruptible power supply (UPS) during storms, or simply switch it off when the grid is unstable. Moreover, inspect external wiring for any cuts or loose connections—damaged cables are a fire hazard and can render the unit inoperable.

Energy‑Efficiency Tips

To keep electricity bills in check, set the thermostat between 22‑24°C and prioritize dry mode. Regularly clean or replace air filters and keep the condenser coil free of dust, as a clean unit cools faster and draws less power. If possible, employ timers or smart thermostats to run the AC only during occupied hours, eliminating unnecessary runtime.

In summary, operating an AC during rain is not a blanket prohibition; it is a matter of informed decision‑making. By selecting the appropriate mode, safeguarding the unit against water accumulation and power spikes, and adhering to energy‑saving practices, households can enjoy a comfortable indoor climate without inflating their utility bills.
