Points to plan for in Horsham

Energy

Fan upgrades and better controls can cut energy use significantly on older units.

Roof and height work

Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.

Hygiene

Drip trays and coils must be kept clean to avoid biological growth.

Working hours

Most Horsham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Who we work with in Horsham

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
