Install Ducted Air Conditioning

Ducted air conditioning units are designed to be completely concealed. They can be housed in a false ceiling and are usually controlled via a wall mounted controller. Their versatility makes it a popular choice for both domestic and commercial requirements. You may have encountered one of these air conditioning systems in a hotel.

A number of our clients opt for ducted air conditioning without an outside unit. This type of AC installation is ideal for restricted buildings such as flats, apartments, listed and conservation areas where you are not allowed to have an external condenser.

How it works

Ducted units are concealed and installed within a suspended ceiling. Traditional air cooled units are connected to an outdoor condenser unit which releases the warm air taken from within the building. Internal water cooled air conditioning units are plumbed into your water supply and use water in a controlled manner to provide cool air. They are an ideal solution for restricted buildings where an outside condenser is not allowed.

I am glad I came across All Comfort Solutions because they are one of the few that offer and install water cooled air conditioning units in the London area. Living in a building where we are not allowed to have outdoor units can limit your choices, but the solution offered by ACS helped us overcome that.Highly recommended!
