FAQ
Common Questions About Air Conditioning in London
Everything you need to know about installing, maintaining, and using air conditioning in your home or business.
The cost of air conditioning installation in London typically ranges from £1,200 to £3,500 for a single-room system, depending on the unit type, room size, and installation complexity. Multi-room or ducted systems will cost more. At Ninja, we offer free site surveys and clear, fixed-price quotes.
We aim to respond to emergency call-outs as quickly as possible; please contact us for our current response times.
For optimal performance and efficiency, domestic air conditioning systems should be serviced once a year. Commercial systems or heavily used units may require servicing every 6 months. Ninja offers flexible maintenance packages to suit your needs.
Yes! Most modern air conditioners are reverse cycle systems, meaning they can heat your space as efficiently as they cool it. They're ideal for year-round comfort and energy savings compared to traditional heating systems.
Portable units are plug-and-play and best for temporary or rental use, but they're noisier and less efficient. Wall-mounted split systems are permanent, quieter, and far more effective for consistent temperature control. We specialise in professional wall-mounted installations.
The size of your air conditioning unit depends on room dimensions, insulation, sun exposure, and usage. A free site survey from Ninja ensures we match the right-sized system to your space — for comfort without waste.
