Thats right! Air conditioning units can provide heating as well as cooling 

Air conditioning units work by using a gas that can be evaporated or condensed at ambient temperatures by either  pressurising or depressurising.

It works in the same as a fridge freezer.

In normal cooling mode, the indoor unit will absorb heat in to the gas through the heat exchanger, because the depressurising of the gas lowers its temperature below that of the room. That gas is then pressurised by a compressor which raises its temperature above the outside ambient air. Then the gas is condensed in the outside heat exchanger into a liquid. This cools it down ready to be used again.

So by reversing the flow the units can be used to provide heat or cooling.

Even at low ambient temperatures air still contains energy in the form of heat. That heat can still be collected and given off to a room to warm it up.

Most residential systems will be small in comparison to commercial systems and will run off a standard 13 amp plug. You might need an electrician to install a plug socket for you, or we can hide cables inside trunking to keep things nice and tidy. We have trade contacts with electricians so we can organise this for you if required.
