AC Repair & Servicing in Perth metropolitan
Perth's climate is hard on air conditioners. Split systems and ducted units here run for months at a stretch through summer, and that kind of load shows up as weak cooling, ice on the coil, water pooling near the indoor head, or a compressor that just won't kick in. This category covers the trades that fix and maintain those systems: fault diagnosis, gas top-ups and leak repairs, compressor and fan motor replacement, filter and coil cleaning, ducted system servicing, and the routine checks that catch problems before they become breakdowns. We list 310 businesses doing this work across the Perth metro area, from small owner-operators to larger commercial and residential outfits.
Not all of them are equal. A proper service includes checking refrigerant pressure, cleaning the condenser coil and indoor filters, inspecting electrical connections, and testing that the system actually hits its rated cooling output, not just a quick filter wipe and an invoice. Ask whether the technician is a licensed refrigerant handler (required by law for anyone touching gas), whether the quote covers parts and callout separately, and how they handle warranty work if a repair fails within a few months.
Our scoring weighs review consistency, responsiveness, and how businesses handle complaints, not just star averages.

Common questions about ac repair & servicing
- How much does AC repair cost in Perth?
- A basic callout and diagnosis typically starts in the $100-150 range, with simple fixes like a capacitor replacement or gas top-up often landing between $150 and $400. Compressor replacement or major ducted repairs can run well over $1,000, since compressors and control boards are the most expensive parts on most systems. Get a firm quote after diagnosis, not just a phone estimate, since the fault often changes the price.
- How often should an air conditioner be serviced?
- Once a year is the standard recommendation for split systems used seasonally, and twice a year (before summer and before winter if it's reverse-cycle) for units that run most of the year or in dusty areas. Ducted systems generally need an annual service at minimum, plus filter cleaning every few months depending on use.
- What should I expect during a standard service visit?
- A proper visit includes cleaning or replacing filters, washing the outdoor condenser coil, checking refrigerant pressure, inspecting drainage for blockages, and testing electrical connections and fan operation. It usually takes 30-60 minutes per unit. If a technician is in and out in under 15 minutes without opening the outdoor unit, ask what was actually checked.
- How do I judge whether an AC repair business is any good?
- Look for a current refrigerant handling licence, clear written quotes before work starts, and a warranty on parts and labour (commonly 3-12 months). Beyond that, check how a business responds to negative reviews: a pattern of ignoring or arguing with complaints is a stronger red flag than the odd bad review itself.
