Frequently Asked Questions About Air Conditioning in Horsham
Common questions from our Horsham customers about air conditioning and ventilation services
How much does air conditioning installation cost in Horsham?
Air conditioning installation in Horsham typically ranges from £1,200 for a single-room wall-mounted unit to £5,000+ for whole-house multi-split systems. The diverse property types across Horsham — from period homes on The Causeway requiring sensitive pipework routing to straightforward new-build installations in Broadbridge Heath — mean costs vary based on building complexity and system size. We provide free, detailed quotes following a site survey of your Horsham property.
Do I need planning permission for AC in Horsham?
Most domestic air conditioning installations in Horsham fall under permitted development and don't require planning permission. However, listed buildings and properties in conservation areas — such as The Causeway and the Park area — will need Horsham District Council approval before work begins. At Ernest Air Cooling, we're familiar with the local requirements and can advise on whether your property needs permission as part of our service.
Can you install MVHR in older Horsham properties?
Yes, we specialise in retrofitting MVHR (Mechanical Ventilation with Heat Recovery) systems into older Horsham properties. Our experienced team adapts ducting routes to work with existing structures while preserving the character of period homes. We've completed successful retrofit installations in properties across The Causeway, Denne Hill, and Horsham Town Centre.
How long does AC installation take in a typical Horsham home?
A single-room air conditioning installation in a typical Horsham home takes around 1 day. Multi-room systems covering 2–3 rooms usually take 2–3 days. Older properties around The Causeway and Denne Hill may require slightly longer for careful pipework routing around period features. We confirm exact timescales after your free site survey and always leave your property clean and tidy.
Do you offer emergency AC repairs in the Horsham area?
Yes, we provide emergency air conditioning repairs across the entire Horsham area, covering both RH12 and RH13 postcodes. Call us on 01273 455584 for same-day response.
