How it works
Tell us about your rooms
Get in touch with the rooms you would like to cool and heat, and we will talk through which range and layout might suit them.
Survey
We look at the rooms and where the indoor and outdoor units could go, so the quote reflects your home rather than a generic spec.
Written quote
You receive a quote for the system we recommend. The price depends on the range, the number of rooms and the installation, so we do not publish one here.
Installation and handover
We fit the system, test it and talk you through how to use it before we finish.
Air conditioning: common questions
- Which air conditioning do you install?
- We fit Daikin air conditioning from three ranges: Sensira (entry-level, single split), Comfora (mid-range, multi split) and Stylish (premium, multi split).
- What is the difference between single split and multi split?
- A single split has one indoor unit connected to one outdoor unit and serves one room. A multi split connects several indoor units to one outdoor unit so you can cool and heat more than one room.
- Are you qualified to install air conditioning?
- Gareth Williams Heating Limited is F Gas certified through REFCOM (company certificate REF1026669, valid to 28 October 2029). You can find the company on REFCOM's public register.
- How much does air conditioning cost?
- It depends on the range, how many rooms you want to cover and the installation, so we quote after we have seen the property. Get in touch to start.
- Which areas do you cover?
- Newport, Cardiff, Cwmbran and the wider South Wales area.
- Is there a guarantee?
- Guarantee terms depend on the unit and the manufacturer's conditions, which can include servicing requirements. We will confirm what applies to the system we quote for.
