AC Not Cooling? Seven Checks Before You Call a Technician

In a hot, humid city an AC that stops cooling is more than an inconvenience. Before you book a visit, these checks sometimes solve the problem in minutes.

Seven quick checks

• Mode and temperature: confirm the remote is set to cool, the temperature is lower than the room, and the fan is not on auto-dry or fan-only.
• Remote and power: replace the remote's batteries and check the plug and the circuit breaker.
• Indoor filter: a clogged filter chokes airflow. Remove it, wash it gently and dry it before putting it back.
• Outdoor unit: make sure the fan is running and nothing blocks the unit; dust, leaves or a cover stop it from releasing heat.
• Room conditions: close doors and windows, and check that the AC is the right size for the room and not facing direct afternoon sun without curtains.
• Ice on the pipe or unit: switch the AC off for a few hours so it thaws, then try again. Repeated icing needs a technician.
• Water leaking from the indoor unit: this usually means a blocked drain pipe or a dirty filter.

When to call a technician

• The outdoor fan or compressor does not start.
• A hissing sound, an oily residue on pipes or ice that keeps returning, which can point to a refrigerant leak.
• Strange smells, loud rattling or the breaker tripping when the AC starts.
• Cooling that is weak even after cleaning the filters.

Do not top up gas by yourself or let anyone add gas without finding the leak first; refilling a leaking system only works for a short time.

How often to service

A service before the hot season, and another if you use the AC heavily, keeps the coils and drain clean and helps the unit cool efficiently. A jet service washes the indoor and outdoor coils with water pressure and is a common choice for a yearly clean.
