When your ducted air conditioning system is working properly, it’s easy to forget it’s even there—until something goes wrong. Regular servicing is the best way to keep your system running smoothly, avoid sudden breakdowns, and make sure every room in your home or business stays comfortable year-round. At Curran, we recommend servicing your ducted or reverse cycle system at least once a year to keep it clean, efficient, and long-lasting.
Our licensed air conditioning technicians will thoroughly inspect your system, clean filters, check for refrigerant leaks, test airflow and electrical components, and make sure everything is operating as it should. We also provide detailed condition reports so you know what’s been done and what might need attention down the track. It’s a small investment that can prevent big problems later—like higher power bills, poor airflow, or a complete system failure when you need cooling or heating the most.

If your ducted aircon has started to act up—blowing warm air, making strange noises, or just not performing the way it used to—it’s likely due for repairs. Other common warning signs include weak airflow, unusual smells, thermostat problems, water leaks, or rooms that aren’t cooling evenly. If your system has shut down completely or is turning on and off constantly, it’s definitely time to call in a professional.
At Curran, we know how frustrating AC problems can be—especially during summer heatwaves or chilly winter mornings. Our technicians are trained to diagnose and repair a wide range of ducted air conditioning faults. We’ll get your system back up and running fast, with honest advice, upfront pricing, and service backed by over 35 years of local experience.
During a typical service, we go beyond just cleaning your filters. Our team will test the system’s performance, clean the internal components, check refrigerant levels, assess duct integrity, and make sure the unit is not under strain. If we find any parts that are worn or at risk of failure, we’ll let you know before problems start. We also check your control systems and thermostat to make sure you’re getting the comfort you expect.
When it comes to repairs, we carry a wide range of parts so we can fix most issues on the spot. Whether it’s a faulty fan motor, a zone control problem, a refrigerant leak, or blocked ducts, we’ll pinpoint the cause and provide a lasting solution. If we think replacing the system might be more cost-effective than a major repair, we’ll talk you through your options—no pressure, just practical advice.

Benny Oldfield2024-09-16 These guys are the business. They are professional and cheap and does not charge anything if they don't do anything (or if you do not want them to do anything when you get your problem explained). They are also extremely friendly. I cannot recommend them enough. I needed a blocked drain fixed and they did that for $93 (in about 1 1/2 hours with no callout fee). They are going to send someone around with a camera tomorrow (no charge) to find the actual problem with the drain. It will be up to me if I then need/want them to do anything else. Holly McEvoy2024-09-12 Sarah our aircon technician was AMAZING, so kind and professional! I will be using Curran for all of our home needs the team are so helpful and speedy!

Had an old leaky electric hot water heater, they were able to come out that morning to get rid of the old unit and provide us with a new model the next business day. Very transparent with all the options and gave expert advice to help us decide. Rob Paton2024-09-02 I engaged Curran plumbing services for a blocked drain and it was the most professional trade experience I’ve ever received. Absolute first class service from Nathan the plumber assigned to my job. Highly recommend. Rachael Peedom2024-08-29 Exceptional customer service. Outstanding knowledge. 100% commitment on finding a solution for the customer. sumguy762024-08-27 After our hot water stopped working, I called Curran Plumbing who organised a plumber to come out the same day and assess our problem. Within 1/2hr of reviewing the issue, Jake diagnosed the problem and gave us a thorough explanation of the issue and what we could do get the hot water back up and running. He was friendly, professional, thorough and quick. 5 star service and quality…thanks again!!!


A well-maintained ducted system can last over 15 years, but neglecting regular servicing can drastically shorten its lifespan. Dirty filters, clogged ducts, and worn components all reduce efficiency and can cause serious damage over time. That’s why Curran offers scheduled maintenance programs—ideal for busy homeowners and commercial properties that can’t afford unexpected downtime.
Preventative servicing helps you avoid emergency callouts and costly repairs by catching problems early. We even offer seasonal tune-ups so your system is ready to perform at its best before the extreme heat or cold hits. You wouldn’t skip a car service for years—your ducted aircon deserves the same attention.
