A buying guide to the ultimate air conditioners

An air conditioner is not just a cooling appliance that brings down the air temperature in a room. Instead, you can use these products for reducing moisture levels or keeping the air warm easily. Most products come packed with a bunch of enticing features that can easily leave you in a trance, making it difficult for you to make the right choice. Owing to this reason, we have created a complete buying guide for helping you invest in the most appropriate air conditioner for your particular needs.

Types of air conditioners

The two major air conditioners you’ll find on the market are freestanding and window-mounted versions. Even though both these types can cool down a room and make summers more tolerable, there are many differences between them you should keep in mind. In the section below, we’ve explained certain factors for helping you decide on which kind of air conditioner you should go with.

  • Freestanding air conditioners are portable and have compact designs including wheels. You won’t be able to move window-mounted ACs, so you should choose an air conditioner depending on your needs and intended use

  • A window-mounted air conditioner has higher cooling efficiency than freestanding versions, this can become a larger factor depending on where you live

  • While installing a window-mounted air conditioner, appropriate plumbing is needed to connect the exhaust pipe to the main drainage. Conversely, freestanding ACs do not require additional plumbing

Key factors to consider when selecting an air conditioner

Cooling capacity

Even though the main function of an air conditioner is cooling down rooms, cooling capacities will differ from one product to another. This feature depends on how quickly an appliance can lower temperatures, the airflow distance, and the compressor technology. For instance, if product A takes 15 minutes to lower the ambient temperature and product B needs only 12 minutes, you should choose the latter. Since it can cool down a room in less time, it will consume less energy over time, saving you money on utility costs. Similarly, you should check the airflow distance for ensuring the appliance distributes and circulates cold air evenly and to the maximum distance.

Operational modes

All air conditioners come with two common operational modes, cool and fan. In cooling mode, the appliance lowers the temperature by compressing the air flowing through its evaporator coil while the fan distributes cold air at varying speeds. If you switch an air conditioner to fan mode, the cooling function will stop temporarily, and only the fan will operate to maintain the temperature. Some products feature a sleep mode where the cooling unit will read the room temperature and alter compression accordingly.

For example, the cooling unit will work faster to reduce heat if the ambient temperature is high. It will also adjust automatically for lower temperatures. If you want to use an air conditioner during the winter season, make sure it has a dehumidifying or heating mode. When an AC is used as a dehumidifier, it reduces the moisture level while lowering the air temperature to a preset value. On the other hand, when you operate the product in heating mode, it will warm the air, offering you relief from the chilly winter months.

Noise levels

Air conditioners have a motor for circulating air within the cooling coil while the inverter compresses air and reduces the temperature. Both these components make sounds when active. So, if you don’t want an air conditioner to disturb your sleep or distract you from work, choose a product that operates within a noise range of 42-56 dB.

Energy consumption

Different air conditioners have varying energy consumption ratings. If you mistakenly choose a product without an energy-efficient design, you’ll end up with high utility bills. The overall efficiency of a product will also be reduced with greater energy consumption. So, you should check whether the product consumes electricity efficiently. Go for a product with a DC inverter unit, it will operate at varying speeds according to the air temperature and prevent excess energy consumption.


Most air conditioners come with remotes letting you control them from your bed, couch, or anywhere else, provided you are within the sensor’s range. Since a remote won’t function if you are out of the range, you can opt for an air conditioner with a smart control feature. You can connect it with your phone through an app and control its operations over a WiFi network. A smart AC unit will also allow you to use voice control via integration with Alexa, Google Assistant, and more. You can also find models with a LED control panel with buttons and indicators for adjusting different settings easily.


Most air conditioners are equipped with removable filters so that you can take them out and wash them. This enhances their longevity and releases blocked filtration pores.

Factors determining the price of an air conditioner

The price range of the air conditioners varies from $162.96-$459, depending on a wide range of factors. These include:

  • If your chosen air conditioner has smart controls like WiFi connectivity or an advanced DC inverter, its price will be much higher than with regular products.

  • Window-mounted air conditioners are usually less-pricey than freestanding models.

  • If your chosen air conditioner has multiple operational modes, the cost will increase more than a product featuring only cool and fan modes.

Maintaining an air conditioner for greater efficiency and longevity

Unless you maintain your air conditioner properly, it won't be able to deliver outstanding, or even standard, performance. You can follow the tips mentioned below to learn about AC maintenance.

  • Make sure to remove dust filters twice a month for washing. This will eliminate the accumulated dust and improve the overall functionality of an AC unit

  • It helps if you don’t leave any windows open while using an air conditioner, it forces the unit to consume more energy to lower a room’s temperature.

  • If you suddenly start hearing whirring sounds coming from an air conditioner, switch it off without any delay and get help from a professional

  • Always switch off the appliance when it’s not in use so that no transient currents can flow through the circuit and increase your utility bills
