Why Orange servicing runs to a different calendar
The long season is heating
July's mean daily minimum at Orange Airport AWS is 0.5 degrees, winters are cold and wet with frequent morning frosts, and AdaptNSW says up to 130 nights below 2 degrees a year are recorded in the Tablelands.
Cooling is light work
January's mean maximum at the airport is 27.4 degrees, and fewer than 10 days a year go above 35. A unit here might cool for a few weeks and heat for months.
Cool temperate
The building code puts Orange in climate zone 7, cool temperate, and its winter daytime maximums are colder than most inland centres'.
What a winter-first service checks
Daikin suggests a licensed technician looks over a unit at the start of every summer. In a heating town, move that visit to late summer or autumn, so any fault turns up before the first frost rather than on a June night.
The heating test is the part people skip. Ask for heat mode to run long enough to reach temperature, with the outdoor unit checked while it works. Daikin says blocked filters can reduce a system's efficiency significantly, and that applies in heating as much as cooling.
The rest is the standard list from our national service guide, including a refrigerant check by someone with a full RAC01 licence.
Normal winter behaviour, and what isn't
Mitsubishi Electric says that in heating, frost forms on the outdoor unit when it's cold and humid outside, and the unit stops for up to 10 minutes to defrost. White vapour from the outdoor unit during that time is normal, and so is water dripping from it. Warm air also takes a moment to start when heating begins.
What's not normal: a breaker that trips often, heating that stays weak after a defrost, ice that keeps building, or a burning smell. Mitsubishi Electric says to stop using the unit and get it checked if the breaker trips frequently, and to turn it off at the breaker if you smell burning. Those need an air conditioning repair, not the next service.
Ask for these on an Orange service
- A heating run long enough to reach temperature, with the outdoor unit checked during defrost.
- Filters, the indoor coil and the fan cleaned on each indoor unit.
- The outdoor coil and the ground around the unit cleared, so defrost water can drain away.
- A refrigerant check by an RAC01 licence holder, with any leak repaired before any refrigerant goes in.
- Any fault written up separately, so you can decide in your own time.
Gas heaters need their own service
Jemena's gas network serves the Central West and Central Tablelands, but a gas heater isn't part of an air conditioning service. Better Health says every type of gas heater should be serviced at least every 2 years by a licensed gasfitter, and Energy Safe Victoria says any gas heater can spill carbon monoxide. Book a gasfitter in the same autumn window. See gas heater servicing.
Your part, and the technician's
You can
- Clean the filters as your manual says, including through winter, when heating runs most.
- Keep the outdoor unit clear of leaves and anything stored against it.
- Leave frost and ice on the outdoor unit alone. Don't pour hot water on it or chip it off.
Leave to a licensed installer
- Cleaning the indoor and outdoor coils.
- Refrigerant checks and leak repairs.
- Electrical faults and a breaker that keeps tripping.
- Gas heater servicing, which is a gasfitter's job.
Questions to ask an Orange technician
- Will you run the system in heating long enough to test it properly?
- Do you hold an RAC01 licence, and what's your RTA number?
- How does the outdoor unit look after several winters of frost?
What we'd do
Our take for Orange
Book the reverse cycle service in autumn, ask for a proper heating test, and get the gas heater serviced by a gasfitter in the same few weeks if you have one. Learn what a normal defrost pause looks like so you don't call someone out for it, and call straight away if the breaker trips. A technician who services heat pumps through tableland winters will know the difference. If you're choosing a new system, start with our Orange page.
