More Cardiff homes and businesses are fitting air conditioning every year, and not only for the summer. Modern units are air-source heat pumps, so the same system that cools the house through a heatwave also heats it efficiently through winter, often for less than electric heating. From a flat in Cardiff Bay to a semi in Cyncoed or an office in the city centre, cooling that pays its way all year is no longer a luxury.
As a Gas Safe registered firm that has served South Wales for over 50 years, Eric Collier & Son design, install, service and repair air conditioning for homes and businesses right across Cardiff and the wider CF postcodes, including CF10, CF11, CF14, CF23, CF24 and CF5.
Whether you want to cool a single room, a whole home or a commercial space, our engineers survey the room, recommend the right system and install it cleanly with minimal disruption. We fit wall-mounted split systems, multi-split setups for several rooms and ceiling cassettes for larger spaces, all to F-Gas standards with a fixed quote up front.
A serviced unit runs colder, quieter and cheaper, and keeps its manufacturer warranty valid. Regular maintenance cleans filters, checks refrigerant and catches small faults before they become expensive breakdowns. We service systems we fitted and systems installed by others, right across Cardiff.
Unit blowing warm, leaking, tripping or making unfamiliar noises? Our Cardiff engineers diagnose the fault, re-gas where needed and get your cooling back working. We cover domestic and commercial air conditioning repairs across Cardiff and the Vale.
We look after air conditioning for offices, shops, salons, gyms and server rooms across Cardiff and Cardiff Bay, from a single office unit to multi-zone systems. Ask about F-Gas compliant maintenance contracts to spread the cost and keep business systems compliant.
Whether your Cardiff property runs on mains gas or LPG, Eric Collier & Son covers both fuel types fully. For gas central heating, that means boiler servicing, system repairs, radiator installation, and full central heating installations across Cardiff.
For LPG properties — including those in the CF3, CF5, and CF15 postcode areas where mains gas isn't always available — the team carries out LPG boiler service, LPG boiler installation, and LPG heating system repairs, including conversion from oil or other fuels. All LPG work is carried out by OFTEC-registered engineers.
Cardiff businesses have different demands from heating systems — higher outputs, more complex pipework, regulatory compliance, and the need for minimal downtime. Eric Collier & Son's commercial heating team serves offices, schools, restaurants, care homes, retail premises, and industrial units across Cardiff.
Services include commercial boiler service and repair, commercial gas boiler installation, commercial central heating installation, planned preventative maintenance contracts, and emergency commercial heating callouts.
A planned maintenance contract for your Cardiff premises means priority response, reduced risk of breakdowns, and full regulatory compliance. Interest-free commercial finance is available. Call 029 20 508711 to discuss a contract.
Cardiff landlords are legally required to hold a current gas safety certificate (CP12) for every rented property with gas appliances. Eric Collier & Son's Gas Safe registered engineers carry out annual inspections across all Cardiff postcode areas, issuing compliant certificates on the same day.
The inspection covers all gas appliances, pipework, flues, and ventilation. If any remedial work is required, it can be carried out by the same engineer in most cases — saving time and a second callout fee.
Engineers cover the full Cardiff city area and surrounding Vale of Glamorgan. All CF postcode areas served.

Yes. Most modern units are air-source heat pumps that run in reverse, so they heat efficiently in winter as well as cool in summer, often cheaper to run than electric heating. Many Cardiff customers use them to lower their winter energy bills.
It depends on how many rooms you want to cool and the type of system. A single wall-mounted room unit starts lower than a multi-room or commercial cassette setup. We give a fixed quote after a free survey, with no obligation. Call 029 20 508711.
