Air Conditioner Buying Guide

Air conditioning units are an essential piece of kit for homes and businesses in hot and changeable climates. At LG, we have a wide range of air conditioners for the home, as well as industrial systems for commercial use. We’ll explain each of these types in more detail below, and look at the size, efficiency and features of our residential AC units, too.

Types of Air Conditioners

Whether you’re looking for a new AC for your home or business, we have a variety of different types to choose from.

Air Conditioners for the Home

These air conditioning units are designed for residential use.

Split System Air Conditioners

Split system air conditioners are ductless and made up of two parts: an outdoor compressor unit and an indoor unit. Hot air is absorbed by refrigerant gas from inside through a pipe connecting the two units; the outdoor unit then releases the heat and pumps the cold refrigerant back into the indoor unit, cooling the space.

Split system units are usually used to cool one or an open plan area.

Heating mode is just reversed process of cooling mode: the unit draws heat in from the heatpump (outdoor), and releases this into the room. Compared to conventional heaters that are not reverse cycle heaters, such as gas heaters or wood heaters whereby the heat energy is created, reverse cycle air conditioners absorb heat by exchanging coil and pump to warm the air indoors.

Benefits of Split System Air Conditioning

Here are just some of the plus points:

• Split system air conditioners are generally more energy efficient
• They’re typically cheaper to run than conventional ACs
• They operate quietly
• Although they will need to be professionally installed by a licensed LG Specialist Dealer, installation is relatively straightforward
• Once they have been installed, you’ll find that they’re fairly low maintenance; they’re easy to clean, and you’ll only need to clean the filter every month or so.

Multi-Split Systems

Multi-split air conditioners are similar to split system units, except that they have one outdoor unit connected to two or more indoor units. This type of AC is good for two or three rooms that are fairly close together – particularly if separate split systems or ducted air conditioning isn’t suitable for your home (if space is limited, for example).

Air Conditioners for Larger Spaces & Commercial Use

If you’re in the market for a new AC for your business or workplace, we can help: at LG, you’ll find air conditioning systems in store that are suitable for large or open spaces.

What Size Air Conditioner Do I Need?

One of the key things you’ll need to think about when buying an air conditioner for your home is sizing (or capacity), which is measured in kilowatts (kW).

If you choose an air conditioner that’s too powerful for a room based on its size, the unit will likely run lots of short cycles to reach the right temperature. This may result in the room being too hot or too cold; additionally, you may find that the room doesn’t dehumidify, which means the air won’t be dry enough, so it’ll be uncomfortable to be in. Overpowered models will also use more power and may experience greater wear; resulting in unnecessarily running and maintenance costs.

Alternatively, if you get something that’s too small (or not powerful enough) for a particular room, you may find that the unit dries the air out too much – which, again, will be uncomfortable. What’s more, you’ll find that the unit may need to run more often at maximum power, which will also lead to premature wear and tear.

Energy Efficiency

Air conditioners are given a tick rating based on how efficiently they use energy: the more ticks a particular model has, the more energy efficient it is. So although upfront costs may be more for a 5 tick rating unit, it will be cheaper to run. Discover more about energy efficient air conditioning with NEA tick rating guide.

Features on Selected LG ACs

Our air conditioners come with a range of handy features that are designed to improve the day-to-day usability of the unit, as outlined below.

ThinQ™

Selected air conditioning units use LG ThinQ™ technology, which allows you to remotely monitor and manage your AC via your smartphone app, and troubleshoot any issues you may have. You can also check your energy usage, including your monthly or weekly usage, via the app.

You’ll notice that some of our air conditioners have built-in Wi-Fi and are compatible with Google Assistant and Amazon Alexa, too. You can turn on the AC or check the temperature using only your voice with this handy feature!

Dual Inverter Compressor™

Dual Inverter Compressor™ is structured to optimize stability and to operate on low noise vibrations.

The twin rotor create stable rotation with low noise and low vibration.

The flow optimization reduced oil discharge and enhanced oil collection.

Concentric Motor
Improved Oil Path Area / Low Calorific Value

Surface Coating
