Air Conditioning Cleaning in London

Blocked filters, dirty coils, and neglected components can cause your air conditioning system to underperform or spread dust and allergens around your property.

FAQ

  • How much does it cost to install air conditioning in a London home?

    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 Arcas, we offer free site surveys and clear, fixed-price quotes.

  • Do I need planning permission to install air conditioning in my property?

    We aim to respond to emergency call-outs as quickly as possible; please contact us for our current response times.

  • How often should my air conditioner be serviced?

    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. Arcas offers flexible maintenance packages to suit your needs.



  • Can I use air conditioning for heating as well as cooling?

    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.

  • What’s the difference between portable and wall-mounted air conditioning units?

    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.

  • What size air conditioning unit do I need for my room?

    The size of your air conditioning unit depends on room dimensions, insulation, sun exposure, and usage. A free site survey from Arcas ensures we match the right-sized system to your space — for comfort without waste.
