Why Choose Service One Heating & Cooling?
Service One Heating & Cooling is highly regarded across Adelaide's southern suburbs for honest advice and skilled installation and repair work.

About Service One Heating & Cooling
The local view around Lonsdale is that Service One Heating & Cooling is the kind of air conditioning team people happily point their neighbours towards. Working across Adelaide's southern suburbs, they handle split system installation, repairs and servicing, along with ducted reverse cycle air conditioning for homes and light commercial properties. Whether it is swapping out a tired old system or sorting out a room that just will not cool, they cover the lot, and the Lonsdale team brings over twenty years' experience in the trade to it.
Ask around and Tony's name comes up again and again, usually alongside his crew: Tristan, Jacob, Geno and the rest of the team get mentioned for being polite, friendly and genuinely easy to deal with. People talk about the honesty side of it just as much as the work itself. One local had a thirteen-year-old unit diagnosed and repaired rather than replaced, saving them a whole new install, which says a lot about how this lot operate. Others mention being talked through every option before anything was decided, with quality gear like Mitsubishi inverters and zoned AirTouch control put forward where it suited.
There is plenty of praise for the way they finish a job too. People who have had them out swear by how tidy the crew leaves the place, right down to cleaning up properly after a full day's install. A tricky ducted repair in a tight roof space, a complex setup that needed extra sensors and recalibration afterwards, a system put into a granny flat with no fuss: the stories cover all sorts of situations, and the thread running through them is clear communication and attention to detail. One household even had them climate-control an old barn for a flower business.
They are fully insured and offer a free, no-obligation quote, and they do emergency call-outs as well. If you are after air conditioning work in Lonsdale, give Tony and the Service One team a call to talk through what you need.
