Frequently Asked Questions

Generally speaking, it is prohibited to deface a Listed building, which can include making penetrations through walls or fixing outside AC units to areas seen by the general public or others. Conservation areas are also subject to similar restrictions as the general look of the area is protected. An alternative option is to consider is installing water cooled air conditioning systems. Get in touch with us if you’d like more information on this.

It depends on the property location. If the outdoor unit is either intrusive to the eye or noise can be heard from the unit which is higher than the maximum allowable decibel reading as per the local council’s legislative requirement, or if the unit is in a Conservation area then yes. Otherwise no it is not a requirement.

The benefits of air conditioning are many. Not only can it provide a natural source of dehumidification when cooling in the summer, but it is also a much cheaper way of heating your premises during the winter. Conventional electric heating or gas fired boilers with radiators is considerably more expensive compared to the cost of running a heat-pump AC unit on heating mode.

Generally, if it’s in a home then at least once a year. If in an office at least twice a year and if in a comms room, then 4 times a year. However, it really does depend on the environment. For example, a shop which is open to the walk-in traffic of the street may need more visits.​

Yes, installing water cooled air conditioning or through the wall air conditioning is the only option you have in a listed or restricted property. Contact us if you would like to discuss getting water based AC in your home.

The electrical power consumption of an average size AC system will be little more than a domestic fridge. The cost of the water consumption element depends on how and what you pay for your water, and indeed the usage characteristics of the user. Water consumption rates vary on unit size and our specialists can advise you according to your requirements.

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.

In water based air conditioners, water is used throughout the system. There are some water based air conditioning systems in the market, such as evaporative coolers, but they are not as efficient as a traditional air conditioning system.

A water cooled system, which we offer is a traditional AC system but with the addition of water use. The features we list above are not available through the other water based system.

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.

In most cases no, water based AC has the internal condenser hidden in your own home, so there is no need for permission.

Air conditioning works by way of transferring heat from the air inside a room into the internal gas and then pumped along the pipework to an outdoor unit where the gas transfers the heat to the external air. The heat exchange process happens when the internal air is passed over a heat exchanger coil called an evaporator. Inside this evaporator is refrigerant that boils off at a very low temperature making the coil very cold. When the warm air passes over it then heat is absorbed from the air into the coil. The reverse happens with the heat exchanger in the outdoor unit.

The only difference is the condenser unit and its placement. The water cooled condenser is installed inside the property and plumbed into the mains water supply as opposed to fixed to an external wall. It uses water instead of air, in a controlled manner, to remove heat from the room.  

There are many reasons why your AC unit might not be working, but the main one is lack of maintenance. Most AC units have a diagnostic facility that tells the user there is a fault. It can be a code on a controller display or a series of flashing lights on the unit.
