About Horsham — Local Knowledge
Horsham is a thriving market town in the centre of West Sussex with a population of around 55,000. It has one of the most attractive town centres in the South East — the pedestrianised Carfax and surrounding Georgian and Victorian streets create a strong independent retail and restaurant scene. The town has a significant commuter population with excellent rail links to London Bridge in under an hour, which drives demand for home office climate control as well as conventional domestic installations. The Foundry commercial quarter and the business parks on the northern fringes of the town house a mix of professional services, tech companies and light industrial occupiers, all of whom require compliant commercial air conditioning.

Recent Case Study — Horsham
AirCon Doctor Case Study — Horsham
Hurst Road, RH12 2EJ
Property: A converted victorian terraced house operating as a dental practice.
Work carried out: installation of two LG wall-mounted split systems — one serving the main treatment room and one serving the reception and waiting area. The Victorian property required careful routing of pipework to avoid visible external runs, achieved by running pipework through the roof void and down the internal party wall. All materials used were clinically appropriate and the installation was completed out of hours.
Outcome: Both treatment and waiting areas now maintain consistent temperature year-round. The practice owner noted that patient comfort had improved noticeably during summer months and that staff were significantly more comfortable during procedures.

In most cases, no. Domestic air conditioning installations in Horsham typically fall within permitted development rights. However, listed buildings, properties in conservation areas (which are common in parts of Horsham) and some flats may require planning consent or listed building consent for external equipment. We advise specifically on planning requirements as part of the free site survey and have experience of local planning authority requirements in West Sussex.
A standard single-room split system installation in Horsham takes approximately 4–6 hours. A two or three-room multi-split system typically takes a full day. Larger commercial or multi-room domestic installations may take 2–3 days. We confirm a specific timeframe in every quotation and work to programme.
All the major brands produce excellent systems, but for domestic installations in West Sussex we most frequently install Mitsubishi Electric and Daikin for clients prioritising reliability and efficiency, and Samsung and LG for clients seeking excellent performance at a lower price point.

F-Gas regulations govern the handling of refrigerant gases used in air conditioning systems. All engineers who handle refrigerant must hold a current F-Gas certificate — working without certification is illegal and invalidates equipment warranties. For commercial premises in Horsham with systems containing more than 3kg of refrigerant, annual F-Gas inspection is a legal requirement. All AirCon Doctor engineers hold current F-Gas certification and we provide full F-Gas documentation on every installation and service visit.
