JMAC Air Conditioning
Jason climbs into your roof before quoting — and talks customers out of callouts they don't need.
Jason appears to be the owner-operator who stays hands-on through the quoting and assessment phase, not just the sales conversation. The small sample size means you should treat these as promising signals rather than statistical certainty — but the phone-honesty behaviour, if it matches your experience when you call, is a useful early indicator of how they operate.

About JMAC Air Conditioning
Jason leads on-site assessments personally — multiple reviews mention him climbing into roof spaces to inspect existing ducting before quoting, which is unusual and saves customers from being oversold unnecessary replacements. Technician Anthony is specifically praised for his work on evaporative systems, bringing a different skill set to the team beyond standard split and ducted installs. The business operates across both repairs and full system replacements, and the reviews suggest they'll genuinely tell you over the phone if you don't need a callout — one customer was walked through a reset after a power outage at no charge. For ducted replacements in older homes with existing ductwork, they stand out by assessing whether legacy infrastructure can be retained rather than defaulting to full replacement, which can represent significant savings. The crew is noted for completing full ducted installs in a single day, disposing of old equipment, and leaving the site clean. GST-registered and operating as a trust entity, JMAC has been trading for approximately a decade in the Mandurah area.
Best for: complex ducted system replacements in older homes with existing ductwork, homeowners wanting an honest second opinion before committing to a large AC quote, and evaporative system repairs in the Mandurah area.

Does JMAC Air Conditioning replace ducted systems in older homes with existing ductwork?+
Yes — and this appears to be a genuine point of difference. At least one customer review describes Jason climbing into the roof to assess whether existing ducting tubes could handle a new unit, rather than insisting on full replacement as another contractor had. If your home has older ductwork you're unsure about, it's worth asking Jason to inspect it in person before accepting any quote that includes full duct replacement.
What do customers say about JMAC's pricing compared to other Mandurah AC companies?+
Multiple reviews in the sample mention significant price differences when customers got a second opinion from JMAC — one customer says they 'saved thousands,' and another notes the first quote they received was double JMAC's price. A third review mentions the pricing seemed great during the enquiry process. That said, this is based on a small sample of 5 reviews, so it's worth getting a written quote from them to compare directly.
Will JMAC give advice over the phone without charging a callout fee?+
At least one customer reports being walked through a free reset procedure over the phone after a power outage, which resolved the problem without any technician visit. The customer specifically noted this saved them the $240 diagnostic fee they'd been quoted elsewhere. This kind of phone triage isn't guaranteed, but it suggests the team is willing to help you rule out simple fixes before committing to a paid callout.
Who are the technicians at JMAC and what are they known for?+
Jason is the owner and is mentioned in reviews as personally attending site assessments, including getting into roof spaces to inspect ducting. Anthony is a technician named in at least one review for evaporative air conditioner repairs, and is described as courteous and professional. The crew that handles ducted installs is noted for completing full jobs in a single day and cleaning up afterwards, including removing old equipment.
What areas does JMAC Air Conditioning service?+
JMAC is based in Mandurah, WA. The reviews don't specifically mention suburbs beyond Mandurah, so if you're in an outer area of the Peel region or further afield, it's worth confirming directly whether they cover your location and whether a travel fee applies.
