Air conditioning units come in different sizes and shapes, and each has its own unique features. The most important thing to look for when choosing an AC unit is that it will provide enough cooling power to keep your home comfortable during hot weather.

Size Matters

If you live in a large house with lots of rooms, then you need a larger system than one that cools only a small room. A good rule of thumb is to multiply the square footage of the space by 1.5 to determine how much cooling capacity you need.

Living in London, you know that summers here can be brutal. That’s why it’s important to choose an air conditioner that provides sufficient cooling power to keep your house cool.

In fact, if you want to save energy and money, you should consider installing a programmable thermostat. A programmable thermostat allows you to set the temperature at which your AC unit turns off and on throughout the day. You can also adjust the temperature setting according to the season. For example, you might turn the AC unit off at night and then turn it back on again in the morning before leaving for work.

Energy Efficiency

You should also make sure that the unit has enough cooling power to keep up with the temperature inside your home. This means that the unit must be able to provide at least 15 CFM (cubic feet per minute) of airflow.

When selecting an AC unit, you should consider the size of your home, the number of rooms you want to cool, and whether you plan to use the system year round or just during the warmer months.

Noise Level

If you live in a noisy area, you will need to choose an air conditioner that produces less noise than other units.

 You should be aware of the noise level created by the unit. In fact, some people find that the noise from an air conditioner is louder than the noise from a fan.

AC units tend to fall somewhere between 25 decibels and 70 decibels, making the loudest unit eight times louder than the quietest. 


You should also check out the installation instructions before purchasing an air conditioner. This will help ensure that everything goes smoothly when installing the unit.

There are many companies that offer installation services, and some of them specialize in providing high quality air conditioning systems. You should choose one that offers a warranty, because if something goes wrong with your system, you won’t have to pay for repairs.


A warranty is something that guarantees that a product will work as expected. It is usually included with the purchase price of a new item. Warranties are often offered by manufacturers, retailers, and service providers. They are typically valid for a certain period of time after the sale.
