Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.

Points to plan for in Watford
Refrigerant rules
Since 1 January 2025, new single split systems holding under 3 kg of refrigerant in Great Britain cannot use refrigerant with a GWP of 750 or more — in practice, R32 or lower.
Conservation areas
Historic streets and listed buildings in and around Watford are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
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 Watford
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
