Planning to rent AC or cooler this summer: Things you can’t afford to miss

There comes a point during the summer when the question is no longer whether you need cooling but how quickly you can arrange it. Temperatures have already been creeping towards 40 degrees in many parts of the country, and forecasts suggest they will continue to rise before the season peaks. At that point, standing in a room that traps heat like a pressure cooker, the decision to get an AC or a cooler becomes non-negotiable.

For many people, buying a new unit isn't the obvious answer. A decent air conditioner costs anywhere between Rs 30,000 and Rs 50,000, sometimes more. A cooler is cheaper, but even that may not be a purchase you want to commit to if you are in a rented apartment, moving cities in a few months, or simply not sure how long the current living arrangement will last. Renting makes practical sense in these situations, and the rental market has grown enough to offer real options at reasonable monthly rates.

But renting a cooling appliance and renting, say, a piece of furniture are not the same kind of transaction. A poorly chosen AC or cooler can leave you paying more on your electricity bill than the appliance saves you in comfort, or worse, break down in the middle of a heat wave with no clear answer on who is responsible for fixing it. The decision requires a bit more thought than just calling the first vendor you find and handing over a deposit. Here is what to keep in mind before you sign any rental agreement, whether it is for an air conditioner or a cooler.

Renting an AC: What to check before you commit

Start with selecting the vendor, not the price

The first thing most people look at when renting is the monthly rate. That is understandable, but the vendor's reliability matters more than an extra hundred rupees saved each month. A vendor with a good reputation will offer a unit that has been serviced before installation, provide prompt support when something goes wrong, and not disappear after collecting the deposit.

Before finalising anyone, ask people in your building or neighbourhood if they have rented from the same vendor. Look at online reviews with some scepticism, but patterns tend to be telling. If multiple people mention delayed responses to complaints or issues with the deposit refund, that is worth factoring in.

Inspect the unit before it enters your home

People skip this step too often. Before the AC is put in and before you pay, please take a few minutes to review it. Tell the vendor to run it in front of you. Check that it has a working remote, that it cools down to the right temperature in a reasonable amount of time, and that it doesn't make any grinding or rattling noises while it's running.

Also, ask specifically whether the gas has been recently checked. An AC low on refrigerant will blow air without properly cooling the room, driving up your electricity bill. Getting this confirmed in writing, or at least verbally with a witness, will protect you later during difficult situations.

Ask the vendor how old the AC unit is

AC technology has improved enough in recent years that the unit's age actually matters. An older AC, even one with a good star rating on its original label, tends to consume more electricity than a newer model of equivalent capacity. That rating was accurate when the unit was new. This happens after years of use, and efficiency drops.

Try to rent a unit that is not more than a couple of years old. This is not always easy to negotiate, but it is worth asking. A newer unit will cool better, break down less often, and cost less to run over a summer when you may be using it 10 to 12 hours a day.

Match the AC capacity to your room size

This is a point that gets ignored in the rush to finalise things quickly. An AC that is underpowered for the room will run continuously without achieving the set temperature, wasting electricity and wearing out the compressor. One that is overpowered for a small room will cycle on and off frequently, which is also inefficient.

As a general rule, a one-ton unit works for rooms up to around 120 square feet. A 1.5-ton unit handles rooms between 120 and 180 square feet. Larger rooms or spaces with significant heat load from direct sunlight may need two tons. If you are renting in a city with intense summer heat, consider going 1.5 tons higher than the standard recommendation.

Choose between split and window ACs based on your room

Split ACs are quieter, look cleaner, and cool more efficiently. But they require drilling into the wall to run pipes between the indoor and outdoor unit, and the outdoor unit needs a surface to sit on, which not every apartment configuration can accommodate.

Meanwhile, window AC units are noisier and slightly less efficient, but they involve less structural work and are easier to install and remove. If your room has a window with adequate space and your landlord is particular about walls, a window AC may be the practical choice. It is also usually cheaper to rent.

Understand the energy rating before you decide

A 5-star or 4-star-rated unit will cost meaningfully less to run than a 3-star unit over a full summer. The difference in electricity consumption between star ratings can be 10 to 15%.

Over months of daily use, that adds up. Try to find a unit rated at least 3 stars. Going lower than that can make the rental a false economy, because the money saved on monthly rent is offset by the power bill.

Clarify the maintenance policy from the vendor

This is the part that causes the most problems. Before you sign the contract, make sure you know who is responsible for what, such as routine maintenance, refilling the petrol tank, making repairs, and replacing parts. Some vendors include all of this in the monthly rent. Some only pay for basic upkeep and charge extra for petrol or repairs.



Knowing this ahead of time will save you a lot of trouble in the middle of summer when the AC stops working, and you find out you have to pay for the repairs.

Discuss security deposit and installation process before finalising

Most rental companies require a refundable security deposit. This is fair, but the amount is often up for discussion. Don't think that the first number you hear is set in stone. Find out if it can be lowered.

Also, confirm whether installation is included and who handles it. Most vendors offer installation as part of the package, but verify this before finalising. A professional installation ensures the indoor and outdoor units are placed correctly, the drainage pipe is routed properly, and the system is checked before being handed over to you.

Renting a Cooler: What to keep in mind

Understanding what a cooler actually does

Before deciding to rent a cooler, it helps to understand what you are getting. An air cooler, also called an evaporative cooler, cools the air by passing it through water-soaked pads. This makes the air cooler and adds moisture. The result is that the temperature feels lower, but it's not the same kind of precise, sealed-room cooling that an AC provides.

Coolers work best in dry places where the humidity is usually below 50% to 60%. In those conditions, they can cool the room by 8 to 15 degrees, making it very comfortable.

On the contrary, in humid weather or coastal climates, they add moisture to already-humid air, resulting in a minimal cooling effect. Knowing your local climate before choosing a cooler over an AC is important.

Choose the right type of cooler for your space

There are three main types of coolers available for rent. Personal or room coolers are compact, designed for individual use in small rooms, and have water tanks ranging from 10 to 20 litres. They need to be refilled daily.

Desert coolers are larger, with tanks ranging from 50 to 70 litres, and are better suited for medium to large rooms. They can run for 10 to 12 hours on a full tank and deliver a significantly stronger air throw. These are the most commonly rented types and usually offer the best value for families or anyone cooling a hall or bedroom consistently.

Tower coolers are slimmer, designed to take up less floor space, and often come with remote controls. They sit somewhere between personal and desert coolers in terms of capacity and are a good choice if space is limited, but you want something more powerful than a compact unit.

Remember to match cooler capacity to room size

Just as with an AC, pairing the right cooler to the right room matters. A small personal cooler placed in a large room will run hard without making much of a dent in the temperature. Desert coolers comfortably cover rooms up to about 300 square feet. For anything larger, consider a larger unit or whether a cooler is the right appliance.

When in doubt about which size to get, lean toward the larger option. A slightly oversized cooler is far less frustrating than one that struggles to keep things cold.

Always inspect the cooler unit before it arrives

Before the cooler is delivered and before payment is made, ask the vendor to confirm that the cooling pads are clean and intact, that the water pump works, and that the fan runs at all speeds. Cooling pads that are dirty, clogged, or starting to smell will produce air that is unpleasant to breathe. A partially blocked pump will significantly reduce the cooling effect.

If you can inspect the unit in person before accepting delivery, do so. Run it for a few minutes, check the airflow at different fan speeds, and verify that the water tank does not leak.

Check the water tank capacity and refilling timings

One practical consideration that often gets overlooked is how often you will need to refill the cooler. A personal cooler with a fifteen-litre tank may need refilling twice a day in peak summer. A desert cooler with a sixty-litre tank can run through the night on a single fill. If you are someone who is out of the house during the day, a cooler that requires constant attention is an inconvenience worth considering before making a choice.

Also, check whether the tank has a gravity or pump-fill option from an external water source. Some larger models support this, which is convenient if you do not want to manually carry water to the tank.

Always factor in ventilation requirements

A cooler won't work in a closed-off room. An AC unit moves air around in the room, but a cooler pulls in cool air from outside, cools it by evaporating it, and then pushes it into the room. There needs to be a way for air in the room to escape for this to work. Keeping a door or window slightly open on the other side of the cooler improves circulation and enhances cooling. A cooler won't work as well if your room doesn't have cross-ventilation.

Understand the electricity cost advantage

This is where renting a cooler makes a clear financial argument. A desert cooler typically consumes between 150 and 300 watts per hour. An AC with a comparable cooling capacity uses 1,500 to 2,000 watts. Running a cooler for 8 hours a day costs a fraction of what running an AC for the same duration would. Over four months of summer, the savings on electricity alone can be significant. Combined with the lower monthly rental, a cooler is a meaningfully cheaper cooling solution for those in suitable climates.

Clarify maintenance responsibility from the vendor

Coolers don't need as much care as ACs, but they do need to be checked on from time to time. If you use the cooler regularly, you should clean the cooling pads every few weeks. If you won't be using the cooler for a few days, you should empty the water tank and wipe it down to stop algae from growing.

Before you rent, ask the vendor if cleaning the pads and doing basic maintenance are included, and what will happen if the pump or fan motor breaks. It's best to choose a vendor who includes maintenance in the package, but at the very least, make sure you know who is responsible for what before you sign anything.
