How internal systems work

Wall mounted internal air conditioning systems are plumbed directly into your water supply. They use the cold water in a controlled manner to cool the air through the piping system. Unlike traditional air conditioning systems, water cooled units do not require an outdoor unit. The internal condenser is usually hidden within the property in a concealed space such as a cupboard or under the kitchen sink.

Frequently Asked Questions

Some of your questions about wall mounted air conditioner answered.

A typical single split type AC unit will take 1-2 days to install. We can give you a good estimate if you contact us and inform us about your property and what you require.

Modern units are very quiet. In the workplace, you rarely notice them while in bedrooms at night time certain specific night set back settings slow the fans down to reduce the cooling requirement in line with falling ambient temperatures.

A single AC unit of average size will run at a similar cost to a domestic fridge as modern technology allows the power element of the unit to speed up and slow down according to the demand.
