Covering Carmarthen and nearby
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.
That includes premises in SA31 and the surrounding districts. We also cover Llanelli, Ammanford and Gorseinon, all within easy reach of Carmarthen.
In Carmarthen we work with offices, shops and hospitality premises, from a single room to a whole floor; each job starts with a heat load check rather than a guess from the floor area.
Businesses across Dyfed can combine servicing with any F-gas leak checks their systems need, which saves a separate attendance.

Before you book in Carmarthen
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.
Working hours
Most Carmarthen businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Access and parking
Town-centre jobs in Carmarthen often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
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.
In Wales, 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.
Common questions in Carmarthen
How much does commercial air conditioning cost in Carmarthen?
A single wall-mounted split typically costs £1,395–£2,350 plus VAT installed in Carmarthen, and a ceiling cassette £2,050–£4,695 per unit. A small shop or office with two to four indoor units usually comes to £4,695–£15,695 plus VAT.
Do you also cover Llanelli, Ammanford and Gorseinon?
Yes. Alongside Carmarthen, we also cover Llanelli, Ammanford and Gorseinon. Each has its own page with local guide prices.
Do you handle landlord consent?
We supply the drawings, unit data sheets and method of fixing your landlord or managing agent will ask for.
Is the survey free?
Yes, for new installations and replacements on the UK mainland. Service, repair and inspection visits are priced before we book them.
Which refrigerant do new systems use?
Most new small split systems use R32, because new single splits under 3 kg in Great Britain cannot use refrigerants with a GWP of 750 or more. Larger systems vary by equipment.
