Petaling Jaya has 112 businesses listed under aircon installation, ranging from one-van outfits working mostly in Kelana Jaya and SS2 to larger teams that handle whole condo blocks in Bandar Utama or PJU developments. Installation covers mounting the indoor and outdoor units, running refrigerant piping and drainage, wiring the electrical connection, and vacuuming the line to remove air and moisture before charging it with refrigerant. Done properly, that last step matters more than most homeowners realize: a poor vacuum job is the single biggest reason new units leak or lose cooling within the first year.
What to look for before you book
Ask whether the installer is comfortable with your specific setup, wall-mounted split unit, ceiling cassette, or ducted system, since not every team handles all three well. Check where they'll run the piping and whether that route needs extra pipe covering or a longer copper run, because both add cost. Get a clear price that separates the unit, the installation labor, brackets, piping, and any wall drilling or trunking. And ask what warranty covers the workmanship itself, not just the compressor warranty from the unit manufacturer.
How our scoring works
We rank contractors on responsiveness, the consistency of their work across jobs, and how they handle problems after installation, not just star averages. For a full breakdown of the criteria, see our methodology page. If you want the shortlist instead of scrolling all 112 listings, our ranked guide to the best air conditioning contractors in Petaling Jaya narrows it down.
