How it works in Chelmsford
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 Chelmsford 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.
Local points to consider
Phasing
In occupied buildings we plan the work floor by floor so the business keeps running.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Plant space
Outdoor units need clear air flow, structural support and safe access for servicing.
Leased premises
If your Chelmsford premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Typical premises in Chelmsford
- 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.
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.
Your questions answered
How much does a VRF system cost in Chelmsford?
Guide prices in Chelmsford run from about £2,650 to £5,350 per indoor unit (whole system), plus VAT. A typical job (office floor of 10–16 indoor units) costs £26,500–£85,995 plus VAT. We fix the price in writing after a free survey.
Do you also cover Billericay, Witham and Maldon?
Yes. Alongside Chelmsford, we also cover Billericay, Witham and Maldon. Each has its own page with local guide prices.
Which postcodes do you cover in Chelmsford?
All of them, including CM1 and CM99. Give us your postcode when you enquire and we will confirm the visit details.
Does a VRF system need F-gas leak checks?
Usually yes. Most VRF systems hold enough refrigerant to exceed 5 tonnes CO2 equivalent, which triggers at least annual leak checks and record keeping.
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.
