How we work in Watford
Survey and loads
We calculate loads zone by zone and check roof or plant space, risers and ceiling voids.
System design
Outdoor units, indoor units, branch boxes and pipe sizes are designed together, including the refrigerant charge and any leak detection.
Phased first fix
Pipework and controls cabling go in floor by floor, often out of hours in occupied buildings. In Watford we agree timings around your opening hours.
Pressure test and charge
The network is pressure tested, evacuated and charged with the calculated refrigerant quantity.
Commissioning
Each indoor unit is commissioned and the controls set up, with as-fitted drawings and F-gas records handed over.
Points to plan for in Watford
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
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.
Refrigerant in occupied rooms
Because one network carries a large refrigerant charge, small rooms on the system are checked against the safety limits in BS EN 378 and may need leak detection.
Working hours
Most Watford 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 Watford
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
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).

What is heat recovery VRF?
A version that can cool some zones and heat others at the same time, moving heat around the building instead of dumping it outside.
When is VRF better than separate split systems?
Usually once you need more than about six to eight indoor units, want central control, or are short of space for outdoor units. One outdoor unit can replace many.
