Reliable Cooling, Installed And Looked After
Coolair air conditioning installation and ongoing support across Mandurah, from the first assessment through to servicing years after the system goes in.
AIR CONDITIONING REPAIRS IN MANDURAH
Parts, Patience And Nobody Calling Back
Getting an older unit looked at can be the hardest part. Calls go unreturned, parts are declared unavailable and you are left sweating through summer waiting on someone. Straightforward air conditioning repairs should not take weeks of chasing, particularly when the fault is a pump or a set of pads.
AIR CONDITIONING MAINTENANCE IN MANDURAH
We Answer, We Attend, We Explain
You get a person on the phone who understands the system and can tell you what happens next. Once we are on site, we diagnose the fault properly and explain it in plain language. Ongoing air conditioning maintenance then keeps the unit in a condition where these calls become rare.

REFRIGERATION SERVICES IN MANDURAH
Evaporative And Refrigerated, Both Covered
We look after evaporative systems alongside refrigerated air conditioning, so we can compare them honestly for your situation. If your home would be better served by a reverse cycle system, we will say so and explain the running cost difference. The recommendation comes from what suits you, not what is easiest to supply.
Why Choose JST Air Conditioning?
Diagnosis Before Recommendation
We find out what is actually wrong with your system before anyone talks about replacing it. That one step saves a lot of people a lot of money.
Repairs, Not Just Replacements
Plenty of breakdowns can be repaired sensibly, so that is what we recommend when it stacks up. When repairs no longer make financial sense, we tell you that too.
Air Conditioning Only
Air conditioning is the whole business, so it gets the whole focus rather than being one service among many. That means specialists on every job, not tradies squeezing your install in between other work.
Every System Type
We work across split systems, reverse-cycle ducted systems and evaporative air conditioning. We also service all the major brands, including Daikin, Mitsubishi Electric, Panasonic, Fujitsu, Samsung and LG.
Licensed & Authorised
We hold ARCtick authorisation AU 067848 and operate under JST Refrigeration and Air Aust Pty Ltd. Refrigerant handling and installation are done properly and by the book.
Local to Mandurah
We are based in Mandurah and cover the Peel Region from Lake Clifton up to Baldivis and inland to Pinjarra. You get one local specialist for repairs, servicing and future work.
RESIDENTIAL AIR CONDITIONING IN MANDURAH
A Price You Can Rely On
Every residential air conditioning job is quoted before work starts, covering the unit, installation, connections and commissioning. You will know what is included and what falls outside it. If something needs attention beyond the quote, we call you with the cost and get approval first.

FAQs About Coolair
We prioritise systems that have stopped completely, especially during a heatwave or at a business premises. When you call, we give you a realistic window rather than a vague promise. Peak summer is busier, so calling early helps. If we cannot get there when you need us, we tell you straight away.
Pumps, pads, motors, belts and controls are generally available for evaporative systems of most ages. Some older control boards are harder to source, and we will tell you if that is the case. Where a part is genuinely unavailable, we explain the alternatives honestly. You are not left waiting indefinitely without an answer.
Pads, pump, water quality, float valve, belts, bearings, cabinet condition and controls are all checked and tested. We clean what needs cleaning and report anything showing wear. You get a summary of the system’s condition before we leave. It is a proper inspection rather than a quick look.
We assess the cabinet, ductwork and major components before recommending either. A sound unit with a failed pump is worth repairing every time. A corroded system that has needed work three summers running usually is not. You get both figures and the reasoning to go with them.
We stop and speak with you before anything outside the quote. Roof frames, duct joins or water connections occasionally need attention once the unit comes apart. You get the cost and our recommendation, then you decide. No extra work is charged without approval.
Yes, we work across light commercial premises including shops, cafes, offices and workshops. Servicing is scheduled around your trading hours wherever possible. We do not take on cool rooms, freezer systems or large commercial mechanical projects. If your job sits outside our scope, we will point you in the right direction.
