Home aircon work covers everything a landed house or condo unit in Petaling Jaya needs to keep split units and multi-split systems running: new installation, servicing and chemical wash, gas top-up, piping and drainage repairs, and troubleshooting for leaks, weak cooling or water dripping from the indoor unit. This category lists 27 businesses in and around PJ that handle residential jobs specifically, as opposed to large commercial or industrial cooling work.
What the job usually involves
A typical residential visit is one of three things. A general service (vacuum clean of the filter, coil and blower, plus a check of gas pressure and drainage) is the routine job most units need every few months. A chemical wash is a deeper clean using chemical solution on the coil and fan, usually done when cooling has dropped noticeably or the unit smells musty. Installation or re-piping is a bigger job: mounting the outdoor compressor, running copper piping and drain hose between units, and vacuuming the line before gas charging.
What to check before you book
Ask what's included in the quoted price: some contractors quote per unit for a basic wash, then charge extra for gas top-up, piping length beyond a standard run, or a high wall bracket. Confirm whether they carry the brand parts they're servicing (Daikin, Panasonic, Mitsubishi, York and similar are common in PJ homes) and whether they give any warranty on installation work or gas top-ups, since a leak that reappears a month later should be a callback, not a new job. It's also worth asking how many technicians will show up and roughly how long the job takes, so you're not caught out by a two-hour wait for a 30-minute service.
How our scoring works
We rank the businesses in this category using consistent criteria such as responsiveness, review patterns over time, and how clearly they price and scope jobs, rather than a single star rating.
