Air conditioning for conservatories & extensions
Glass-heavy extensions and conservatories are the hardest rooms in a house to keep comfortable. A correctly sized split system handles both the summer overheating and the winter cold.
Why these rooms struggle
Large areas of glazing let in a lot of heat on a sunny day and lose it again at night. Conservatories and orangeries can be uncomfortable for much of the year: too hot in summer, too cold in winter. Bi-fold doors and roof lanterns on modern extensions have the same effect. Blinds help, but they do not remove heat that has already got in.
Sizing for solar gain
Sizing is where these rooms are often got wrong. The cooling load depends on glazing area and type, orientation, roof construction and any shading. We work it out from the room, not from floor area alone, so the system can keep up on the hottest afternoon without being oversized for the rest of the year.
Heating as well
Because most split systems reverse, the same unit can warm a conservatory in spring and autumn and extend the time the room is usable, without extending the central heating into a space designed to lose heat.
Building work and electrics
If the extension is under construction, design it in at first fix and the pipework can be concealed. Where an existing circuit cannot take the load, Somerset Sparks provides the supply — see new builds and extensions.
Common questions.
Can you air condition a conservatory?
Yes. It needs a correctly sized system for the glazing, and the outdoor unit and pipework planning to suit the structure.
Will it work with a glass roof?
Yes, but the cooling load is higher, so the system is sized larger. Solar control glass or blinds reduce the load.
Can I add it to an extension that is already built?
Yes. Pipework is surface-run or concealed where the structure allows.
