Check out these powerful features of the LG Electronics LW1214HR air conditioner that most customers find exceptional:

  1. It comes from a very reliable brand

Customers who have already bought other LG Electronics home appliances pretty much already know how LG works in improving lives with their endless innovations. It seems like they are always one step ahead of their competitors. For this, they all know that the LG Electronics LW1214HR will be a great addition to their growing list of LG Electronics home appliances.

This air conditioner/heater comes with a Gold Fin Anti-Corrosion coating which is purely responsible for keeping the unit beautiful for a longer period of time. You might not even notice how long it has been that you are using the unit because it still looks like new.

  1. It is easy to install and easy to use

In contrary to other air conditioners today that comes as it is without any tools to help with installation, this LG Electronics LW1214HR comes with its own Easy-to-Use Installation Kit and clear manual. As LG puts it, anyone can get cool with the greatest ease because of this kit. It has everything you need to install the air conditioner in the fastest, safest, and easiest way possible without causing you a back strain.

If installation is easy, then using this air conditioner/heater is even easier with a couple of useful controls that lets you choose between 2 different speeds for cooling, heating, and in fan mode. In addition, there is a remote control that lets anyone take full control of the temperature even at the far end of the room. There also is a 4-way air deflection which lets you direct air where you exactly want it to be.

  1. It offers in-home service

Almost all the air conditioners today do offer some sort of warranty but what is great about this LG Electronics LW1214HR is that it offers in-home service which is ultimately convenient for just about anyone. This lets you save on gas, effort, and time that would otherwise be needed if you have to bring the unit to their service center.


While some customers had initial expectations and qualms about this product, they sure are glad for taking the risk because this LG Electronics LW1214HR is simply awesome. It needs a higher voltage of electricity which normally raises a concern for energy and noise. Amazingly, noise is almost nonexistent and the electric bill would not shock you. Just get your local electrician to install a 230V socket or do it yourself if you have the knowledge.

However, some customers say that when used in really large rooms, the cold air tends to stay near the floor as the warmer air stays near the ceiling. This is certainly more applicable to those with high ceilings. For that, some consumers remedied it by installing a ceiling fan.
