What Sub-Cool FM does
Sub-Cool FM is a privately held, Crawley-based specialist air conditioning and mechanical services contractor operating across the United Kingdom, with historical roots in the South-East (Sussex, Surrey, Kent, Hampshire, London). Founded by engineer Jacob Swei, the company designs, supplies, installs, and maintains climate-control systems for three end markets: residential homeowners (conservatories, loft conversions, extensions, new builds), small and mid-sized commercial premises (offices, retail, salons, restaurants), and larger corporate/institutional clients (warehouses, healthcare facilities, places of worship, government buildings). The company also delivers an emergency call-out and reactive repair service.
The company's core technical offering centres on VRV(F), single- and multi-split systems, ceiling cassettes, ducted air conditioning, MVHR (mechanical ventilation heat recovery), cold rooms, hot-water heat pump systems, and Panasonic Nanoe-X air purification, installed under top-tier brand accreditations including Mitsubishi Electric Diamond Quality Partner and Business Solutions Partner, Daikin D1 Business Partner, and Panasonic Premier Solutions Partner. Service is delivered by manufacturer-trained in-house engineers (F-gas/Refcom certified, Alcumus Safe Contractor accredited), with smart Wi-Fi/MELCloud-based remote control available on installed units. The company markets primarily through Checkatrade (10/10 rating, 9.99 score), a YouTube channel, a branded podcast ('The Outspoken Engineer'), and SEO-optimised local landing pages.
Commercially, Sub-Cool FM operates a sales-led, project-based model. Revenue is generated through three streams: one-time equipment installation (the largest share, priced per project with quotes following free site surveys), recurring service and planned-preventative-maintenance contracts, and reactive/emergency call-out work. Residential installations benefit from a reduced 5% VAT rate, and seasonal promotions (e.g. up to 15% autumn discount) are used to smooth demand. Bespoke commercial and government projects (e.g. £100k Network Rail depot, Cambridge Magistrate's Court chiller) are quoted individually, often on multi-year frameworks. Headcount is small (7 employees), the company is bootstrapped with no disclosed institutional funding, and ownership is concentrated with the founder.
