Aircon Running Costs in Perth: 6 Ways to Keep Them Down
Aircon running costs are on every Perth household’s mind through summer, when the unit works hardest. The good news is that aircon running costs are not fixed, several things you control affect them. Here are six ways to keep aircon running costs down without sweating through the heat.
1. The right size unit
One of the biggest drivers of aircon running costs is whether the unit suits the room. An undersized unit runs flat out and struggles; an oversized one cycles inefficiently. A correctly sized aircon is the foundation of reasonable bills, which is why sizing matters at installation.
2. Set a sensible temperature
Every degree cooler pushes aircon running costs up. Setting a moderate temperature rather than the coldest possible keeps you comfortable while easing the load. It is one of the simplest ways to manage the bill, and small adjustments across a long summer add up.
3. Use it efficiently
Habits shape aircon running costs: closing doors and windows, using timers, cooling the rooms you are in rather than the whole house. Running a unit in a sealed room is far more effective. Simple, efficient use is one of the easiest levers anyone can pull.
4. Keep it maintained
A neglected unit costs more to run, so maintenance directly affects aircon running costs. Dirty filters and coils make the aircon work harder for less cooling. Keeping it serviced keeps the costs down and extends the unit’s life, which is money saved twice over.
5. A sound electrical setup
The electrical side influences aircon running costs too: an aircon on an overloaded circuit or struggling supply does not run at its best. A dedicated circuit and adequate switchboard capacity let the unit operate as designed, supporting the efficiency that keeps bills in check.
6. Consider efficiency when buying
When replacing a unit, its efficiency rating shapes aircon running costs for years. A more efficient model costs more upfront but less to run. Weighing efficiency against price at purchase is one of the highest-impact decisions for the long term, especially given Perth’s long cooling season.
Zoning and ceiling fans help
Cooling only the rooms in use, and running ceiling fans alongside the aircon, both trim what you pay. A fan lets you set the aircon a little warmer while feeling just as cool. Small additions like these reduce how hard the unit has to work across the summer.
Insulation and shade help too
How well the room holds cool air matters as much as the unit. Good ceiling insulation, closed blinds against the afternoon sun, and sealing draughts all mean the aircon works less to keep you comfortable, and that shows up directly on the bill across a hot summer.
When high bills signal a fault
A sudden jump in aircon running costs can signal a problem, a failing unit or an electrical fault making it work too hard. If it comes with tripping, heat or a burning smell, treat it as urgent, that is when an after hours electrician near me is the right call, not something to run through.
Why use a licensed electrician
The electrical foundation behind aircon running costs, circuits, isolators, switchboard capacity, is licensed work. A licensed electrician makes sure the setup supports efficient running. The Energy Rating (Australian Government) explains how efficiency affects what you pay to run it.
