    Air Conditioning Installation

    Posted 01 January

    From start to finish, Advantage Air Systems have been very professional and organised. Andy guided us through product options with detailed drawings. We were having our loft converted at the same time and they worked around the team doing that build so not a straightforward installation for them. The installation itself was professional and tidy, with all being very friendly and courteous. Would definitely recommend.

    Great addition to the home. Wish we had done it years ago.

    Posted 14 October 2025

    We have had 5 units installed. 2 floor level units which will also be used to heat the new rooms in our loft conversion and three higher wall units in existing rooms for mainly air con . The cost is well worth it for the value it adds to the home. We are so pleased with the work. Adam and Charlie were great to deal with from start to finish. Highly recommend.

    Air-conditioning supply & installation

    Posted 23 May 2025

    Advantage-asl were an excellent company to use for aircon in our newly converted loft, installing units to two bedrooms. The whole experience went smoothly, from the initial meeting with Adam looking at plans on site, discussing the options, getting a quotation, to liaising with our other tradesmen to do first fix and finally completing the installation giving us clear operating instructions. Charlie and his colleague were on time, easy to have on site (we were living here) and left no mess when they left. I wouldn't hesitate to recommend Advantage Air Systems.
