Is it set to cool, with the temperature below the room? Do the remote batteries work?
Cooling guide
AC is on but the room is still warm. Why?
Not every cooling problem is a broken AC. Work through the common causes below, then call us if it still will not cool.

Check these first.
Four checks you can do safely. Anything involving gas or electrics needs a technician.
The filter
A clogged filter chokes airflow. Rinse or replace it if you can reach it safely.
The breaker
A tripped breaker can stop the outdoor unit while the indoor fan still runs.
The room itself
Open doors, sun-facing glass or a unit that is too small for the space will keep a room warm.
What the cause usually is
If air is weak
Weak airflow usually means a dirty filter, a frozen or dusty coil, or a failing fan. A clean fixes it often; ice on the pipes needs a technician.
If air is cool but the room never catches up
This points to size, sun load or air leaking out. A unit too small for the room, or a room with large west-facing windows, struggles. Blinds, closed doors and sealed gaps help.
If air is warm
Warm air from a running unit often means low refrigerant, a compressor or outdoor fan fault. Do not keep running it; book an inspection through our AC repair service.
Lower the bill while you are at it
Regular servicing keeps coils clean, so the unit works less for the same cooling. Read about system choices if yours is old, or see maintenance plans.

Questions we get asked.
Why does my AC blow warm air?
Common causes are low refrigerant, a failed compressor or outdoor fan, a dirty coil or a control fault. A technician should check, as gas and electrics are involved.
What temperature should I set my AC to?
Many people find 24 to 25 degrees comfortable. Setting it much lower does not cool faster; it makes the unit run longer.
Why is there ice on my AC?
Ice usually means low airflow or low refrigerant. Switch the unit off to let it melt and book an inspection.
How often should I clean the filter?
In dusty areas, every few weeks during heavy use. Replace it if it is damaged.
