FAQs
Air Conditioning Questions, Answered
Everything most people ask before booking a AirCon Sussex air con install.
How much does air conditioning installation cost?
Guide prices for fully installed Daikin air conditioning start from £1,495 for a small room and rise based on room size, unit type and installation complexity. Use our instant quote tool to see a price for your specific room in under a minute.
Can I pay monthly?
Yes. Finance is available from £19/month through our finance partner Novuna Finance, subject to status and credit check. AirCon Sussex acts as a credit broker and not a lender.
Can air conditioning heat as well as cool?
Yes. Modern Daikin air conditioning units use reverse-cycle technology, which means the same unit cools in summer and provides efficient heating in winter — ideal for UK weather.
How long does installation take?
Most home air conditioning installations are completed in less than a day, although exact times vary based on access, pipework runs and whether multiple units are being fitted.
Is air conditioning suitable for bedrooms?
Absolutely. Daikin wall-mounted units have a whisper-quiet sleep mode, gentle airflow and precise temperature control — perfect for sleeping comfortably on warm nights.
Do I need planning permission?
For most UK homes, planning permission is not required for a standard wall-mounted air conditioning install. Listed buildings, flats and properties in conservation areas may need approval — we’ll advise during the free survey.
Do AirCon Sussex install in my area?
AirCon Sussex cover Billingshurst, Horsham, Crawley, Worthing, Chichester, Brighton, Eastbourne and the surrounding West Sussex, East Sussex and Surrey areas. Pop your postcode into the quote tool to check.
Is the price final?
The online price is an instant guide price. After a free, no-obligation survey we’ll confirm the final fixed quote based on the exact unit, room layout, pipework and any special requirements.
What brand of air conditioning do AirCon Sussex install?
We specialise in Daikin air conditioning units, supplied with up to a 5-year warranty. Daikin is known for quiet operation, high efficiency and excellent reliability.
Can I get air conditioning for a garden room or home office?
Yes — garden rooms and home offices are some of our most popular installs. A single Daikin unit provides both heating and cooling, making the space usable all year round.
