Why your aircon is blowing warm air
Most cooling troubles trace back to one of these four issues. Here is how to identify what is happening before booking a technician.
Hissing noises, ice on copper pipes, or warm air output
Refrigerant does not get used up over time. If levels are low, there is almost always a slow leak in the connection joints or coils.
Weak airflow, musty odors, and water dripping from the fan coil
Accumulated dust and mold suffocate the blower wheel and evaporator coil, preventing cold air from reaching your room.
Outdoor unit humming loudly, tripping circuit breaker, or not kicking in
The compressor pumps refrigerant through the system. A worn capacitor or damaged motor stops the cooling cycle completely.
Fan running continuously with no cold air despite low temperature setting
Remotes occasionally get shifted to 'Fan Only' or 'Heat' mode, or the indoor ambient temperature sensor becomes miscalibrated.
Try these steps before calling for repair
Simple checks can sometimes solve the problem right away without spending on a service call.
