Air Conditioning Done Properly, From First Visit to Annual Service
JAC Air Conditioning Ltd is a family run company that started in West Sussex in 2010 and now works from two bases, one in Horsham and one in Lincolnshire. We handle everything from a single bedroom unit to a plant room full of air handling kit, with the same care on every job.
Most of our work comes through recommendation. That happens because we turn up when we say we will, we size the system to the room rather than to the price list, and we finish to a standard we would be happy to live with ourselves.
One team for every stage of the job, so nothing gets lost between trades.

Seven things we do day in, day out, each handled by our own engineers, and the data sheets for the systems we fit. In Horsham that includes air handling maintenance and commercial AC servicing for local businesses. No subcontracting the work out and hoping for the best.

Quiet Confidence, Backed by a Certificate
There is no mystery to good air conditioning work. It comes down to sizing it right, brazing it properly, vacuuming it down and coming back to service it.
REFCOM F-Gas Certified
Company certificate REF1019419, valid to 25 May 2028. Refrigerant handling is regulated and an uncertified installer cannot legally commission your system.
One Team, Start to Finish
Jay and Oscar quote the work and do the work. Nicola is in the office and answers the phone. Nothing is subcontracted out and forgotten.
Free, No Obligation Quotes
A proper survey, a written price with the units named on it, and honest advice about whether you need what you think you need.
Sized on the Room
An undersized unit runs flat out and costs a fortune. An oversized one short cycles and never dries the air. We measure before we quote.
Every Major Brand
We install Mitsubishi, Daikin, Fujitsu, GENERAL, Samsung and LG, and we service and repair every major brand, not only the ones we fit.
We Leave It Clean
Trunking lined up, holes made good, boxes and offcuts away with us. You should not be able to tell we were there apart from the unit on the wall.
