Air Conditioning Installation
A new system, sized right
and installed by a licensed crew.
From a single split system to a fully zoned ducted setup, Standby handles the whole install: site assessment, sizing, the physical install and the compliance paperwork at the end.
A wrong-sized system costs you twice
An undersized split system runs flat out and never quite cools the room. An oversized one short-cycles, switching on and off before it properly dehumidifies the air, which is why a "bigger unit" doesn't always mean a more comfortable house. Both mistakes show up on the power bill and both are avoidable with a proper site assessment before anyone quotes a number.
Standby sizes every system against the room's orientation, insulation, ceiling height and window area, not a rule-of-thumb chart. That is the difference between an install that works in February and one that gets a callback in the first heatwave.
From first call to handover
Step 1
Site assessment
We look at the room, the wall or roof space available, where the outdoor unit can sit and any access issues before quoting. For ducted jobs this includes a walk through the roof cavity.
Step 2
Sizing and quote
You get a fixed quote for a system sized to the space, with the brand, model and capacity specified in writing, not a range.
Step 3
Install day
Licensed, Certificate 3 trade qualified tradesmen complete the mechanical and electrical work, run the refrigerant lines and mount the indoor and outdoor units.
Step 4
Compliance and handover
Every install is signed off to Australian standards, refrigerant handling is logged per ARC requirements and you get a walkthrough of the controls before we leave.
Step 5
First-year maintenance
Two maintenance visits are included in the first twelve months at no extra cost, so the system gets checked before it has a chance to develop a fault.
Split system or ducted?
Most homes fall into one of two camps. A split system cools or heats a single room or open-plan area, installs quickly and suits a bedroom, living room or granny flat. A ducted systemconditions the whole house through hidden ductwork and a single control panel, with zoning so unused rooms aren't paying to be cooled. Full detail on each, including typical cost ranges, sits on the dedicated pages: ducted air conditioning and split system air conditioning.
Licensed, insured and still around after handover
Every tradesman holds a Certificate 3 trade qualification. Standby carries a refrigerant purchasing licence through the Australian Refrigeration Council and $20 million in public liability insurance, and the business is an accredited NSW Government rebate installer, so an eligible upgrade returns $200 to $300 through the government rebate.
The install doesn't end the relationship. A free first year of maintenance, two visits included, comes standard, and the same crew who installed the system handles ongoing servicing and after-hours breakdown calls afterwards.

Common questions
How much does it cost to have an air conditioner installed?
A single split system install typically runs $2,000 to $3,500 depending on unit capacity, brand and how far the outdoor unit sits from the switchboard. A ducted system costs more given the extra ductwork and zoning, usually starting around $8,000 for a smaller home. We confirm an exact figure after a site visit, not before one.
What is the $5,000 rule for air conditioners?
It's a rule of thumb some tradespeople use, not an official regulation: if repairing an existing unit would cost more than roughly half the price of a new system, replacement usually makes more financial sense than another repair. It's a starting point for the conversation, not a fixed line.
What should I look for when choosing an air conditioning installer?
Check the installer holds a Certificate 3 trade qualification and an ARC refrigerant handling licence, since both are needed to legally install and charge a system. Ask how they work out the sizing: a proper assessment looks at room volume, ceiling height, window orientation and insulation rather than floor area on its own. It also helps to know who you call directly if the system needs attention under warranty.
What air conditioning brands should I avoid?
Steer clear of unbranded or grey-import units with no local parts supply or warranty support in Australia. Standby installs Daikin, Mitsubishi Electric and Fujitsu, all of which carry established local warranty networks and readily available parts.
Can I get the NSW government rebate on a new air conditioner?
If the system qualifies under the NSW Energy Savings Scheme, yes. Standby is an accredited NSW Government rebate installer, and an eligible upgrade typically returns $200 to $300. Full eligibility detail lives on our dedicated rebate page.
Do I need council approval to install a split system or ducted air conditioner?
Most standard residential split system and ducted installs don't need council approval, but heritage overlays, strata properties and some external unit placements can trigger requirements. We flag it during the site assessment if your property looks like it might need a check.
