Things to check in Harrow
Space
Units need space in the ceiling void or a plant area with access for filter changes.
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.
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Typical premises in Harrow
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
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.
