About Rooftop Packaged Units
Rooftop packaged unit installation and service in London & the Home Counties for supermarkets, warehouses and retail.
Our rooftop packaged units work across the UK is delivered by directly employed, REFCOM F-Gas registered HVAC and refrigeration engineers — never sub-contracted. Every job is scoped properly before we attend, priced as a fixed written quote with no hidden extras, and finished with a same-day service report covering pressures, temperatures, electrical readings and any refrigerant added or recovered. We work to the standards laid out by CIBSE TM44, BESA SFG20, the F-Gas Regulation (EU 517/2014 retained) and manufacturer guidance for every major brand we touch.
We deliver rooftop packaged units for a full mix of UK sectors — corporate offices, restaurants and dark kitchens, hotels and serviced apartments, retail units and shopping centres, schools and academies, GP surgeries and clinics, gyms and leisure venues, server rooms and data centres, light industrial and warehousing. Whether you operate a single split unit or a multi-floor VRF and chiller estate, the same engineer can carry out the work, log it and, where needed, hand you the documentation your insurers, landlord or compliance officer expects.
Common issues we resolve as part of rooftop packaged units include weak cooling or heating output, refrigerant leaks, frozen coils, blocked condensate drains, error codes and lockouts, noisy fans and compressors, failed PCBs, contactors and capacitors, dirty filters and evaporators, poor airflow balance, and controls that no longer match how the building is actually used. If a fault is uneconomical to repair we'll say so up front and quote a like-for-like or higher-efficiency replacement — never an unnecessary sale.
