Using an AC and dehumidifier together this monsoon? Your electricity bill may surprise you

HIGHLIGHTS

Using an AC and dehumidifier together can increase electricity use.

Running both devices may add to your monthly power bill.

Regular cleaning helps both appliances work efficiently.

The monsoon comes with a relief but also brings many issues, and to deal with them, the users turn toward dehumidifiers. However, at times you may feel like the device is not enough when run alone, and users may want to run the AC as it feels humid. It sounds like a smart combo on paper where AC cools the air while the dehumidifier pulls out extra moisture, making the room feel more comfortable faster.  But this comes with a hidden cost which most people do not think about unless they have been served with their electricity bill. Follow along with the article if you’re not aware of the cost of running an AC and a dehumidifier together.

AC and dehumidifier: Performance

When you use an AC with a dehumidifier, it removes the humidity from the room while maintaining the room temperature. The AC ensures that your room feels cool, whereas the dehumidifier deals with moisture, which makes the air humid. 

Using these two devices together makes the rooms cool much faster and does not feel clammy, but it also implies that the AC will be working extra hard because the dehumidifier produces some heat along with the process of work.

AC and dehumidifier: Maintenance

Both appliances need regular care during monsoon, since humidity levels are at their peak. AC filters are supposed to be cleaned after two weeks to prevent mould formation, while dehumidifier tanks need to be emptied and washed every day in order to prevent bacteria formation. Failure to maintain this equipment is not only likely to affect its performance but is also bound to bring about bad odours within the house.

AC and dehumidifier: Electricity consumption

An AC usually consumes about 1.5 – 2 units of power per hour depending on its star rating, which works out to roughly Rs 10 – 14 per hour. A dehumidifier, on the other hand, uses about 0.3 – 0.7 units per hour, costing around Rs 2 – 5 per hour.

If you use both together for about 6 hours, then each day the extra expense for using the dehumidifier comes out to around Rs 12 – 30 per day, which amounts to approximately Rs 350 – 900 extra per month on the basis of the additional usage of the dehumidifier alone.

AC and dehumidifier: Price

A decent inverter AC can cost anywhere between Rs 28,000 and Rs 45,000, depending on capacity and brand. A basic home dehumidifier adds another Rs 8,000 to Rs 20,000 to your budget. Together, the upfront cost and the added running expense mean this combo works best only if humidity troubles you regularly, not just occasionally.
