Carmarthen and surrounding areas
In a town like Carmarthen, a single wall unit for a shop or a cassette for a surgery makes a real difference in summer. Swansea is about 36 km away.
We work across Carmarthen's postcode districts, including SA31. We also work in nearby Llanelli, Ammanford and Gorseinon. In Carmarthen, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.

How we work in Carmarthen
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 Carmarthen 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.
What to think about in Carmarthen
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 Carmarthen 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.
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.
Who we work with in Carmarthen
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
Compliance in Wales: 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).

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.
How long does a VRF system last?
With regular servicing, commercial VRF equipment commonly runs for 15 years or more. Lifespan depends on use, maintenance and the operating environment.
