Buyers Guide for 1-ton window air conditioner

Energy consumption

Always look to buy a product that saves most of your energy. New air conditioners come with better insulating material. It helps you give a better sealing unit around the air conditioners so that the cool air does not go outside the room.

Noise level

Most of us prefer to use ACs at night, and if it is too noisy, you might not be able to sleep well and will disturb your sleep. So before buying, check the decibel levels of the AC when running on full power.

Window location

Air conditioners do a better job by blowing the air in one direction. If you need to cool the entire room uniformly, the AC has to be located centrally. Nowadays, most of the air conditioners come along fans which swivel on both sides, proving to give out better results.

Install it correctly

A window air conditioner gives out the best result only when it is installed and positioned in the best way. Look around appliances around the units that generate heat from it and always install them away from the ACs.

Check Filter Location

Make sure you position your filters in the best place because you need to frequently access it to clean it after using it for sometimes. Filter cleaning is a very important part while using a window air conditioner.

Intelligent cooling

With advancement in technology, companies have come up with intelligent cooling systems that can detect the temperature, humidity and volume of air in the room and cool accordingly. This makes sure that you are comfortable at all times.

Check the warranty

Warranty on ACs generally comes separately for parts like the compressors, the fans, the blower, etc. So before buying, make sure that each of these parts come with a long warranty period.

Inside your budget

The most important factor while buying a product is its price. Set a budget inside your head and buy something which fits inside your budget.

Electrical Requirements

The window ACs are commonly used in every domestic and small commercial place. Before buying the window AC, make sure the electric system supports the ACs and meet the need of the unit’s electrical requirement like voltage, amps, and watts.

The window ACs are a bit more powerful than other household appliances, so you should check if the model you’re planning to buy needs special electrical wiring.


Window air conditioners need timely maintenance as they can be exposed to outside dirt and other rubbish, which can gather inside or on the back. The dust on the air filter will eventually reduce the effectiveness of your air conditioner if left untreated.


A window AC unit is designed to fit inside standard double-hung windows, but you can install it inside a wall space created especially to fit in the AC. Dimensions of the window should be measured properly, especially the width, and then compare it with the AC’s specifications.

If the window turns out to be narrow, then the custom fitting will be needed. But if the window is bigger than the AC, make sure to inform the installation service providers who might come with an installation kit. 

Energy Efficiency

A higher energy star rating implies that the conditioners will use lesser power than the other non-rated ACs. Go for units with three or more stars.

An energy efficiency measurement indicates the BTUs used by the unit uses per watt of power. The EER can be around ten. You can save your operating costs by looking for energy-efficient units.
