Why You Shouldn’t Set Your AC Below 20°C | EvidiAir

Many Gold Coast families think that lowering their air conditioner below 20°C will cool the home faster. This is a common misconception that leads to high energy bills and unnecessary strain on your system. Here is the real truth behind low AC settings and how to cool your home efficiently with support from EvidiAir Air Conditioning Gold Coast.

What People Believe About Setting the AC Below 20°C

Air conditioning is essential during Gold Coast summers. Many households set their units to 19°C or below hoping to cool the room quickly.

Why This Belief Is Wrong

When your AC is set below 20°C:• The compressor runs at maximum capacity for too long• The outdoor unit overheats or cycles excessively• Cooling becomes less efficient, not more.

This puts unnecessary stress on your system and increases running costs.

The Real Impact of Setting Your Air Conditioner Below 20°C

Higher Electricity Bills

Extreme temperature settings force your AC to consume significantly more power. On hot Gold Coast days, the unit struggles even harder.

Reduced System Lifespan

Constant overload shortens the life of the compressor and major internal parts. This leads to early breakdowns and higher repair costs.

Overheating and Safety Risks

On days reaching 38–40°C, systems running 24/7 below 20°C can overheat, shut down or become a fire risk. Many emergency callouts during heatwaves happen due to this exact issue.

How to Cool Your Home Efficiently on the Gold Coast

Set the Temperature Between 25°C and 28°C

This is the most efficient temperature range for comfort and performance.

Keep Doors and Windows Closed

Prevent cool air from escaping. Use blinds or curtains during peak sun hours.

Clean Your Filters Every 2–3 Weeks

Dust and clogged filters force the system to work harder and burn more power.

Use a Fan With the Air Conditioner

Fans circulate cool air better, helping you feel cool even at higher AC settings.
