Why is my Gree CAS12HP230V1AC not running efficiently?
Your Gree Air Conditioner is designed for years of peak efficiency with routine maintenance. Check for obstructions blocking airflow into the room. Clean a dirty or blocked indoor air filter that is restricting airflow into the system. Seal outdoor air leaks in the room space from doors or windows. Relocate other heating sources in the room space, if possible.
Why does my Gree CAS12HP230V1AC Air Conditioner smell bad when I start it?
Unpleasant odors from your Gree Air Conditioner typically result from mold or mildew forming on the coil surfaces or air filter. Wash the indoor air filter in warm water with mild cleaner. If odors persist, contact a qualified service professional to clean the coil surfaces.
Why does my Gree CAS12HP230V1AC Air Conditioner make a water flowing sound?
It is normal for your Gree Air Conditioner to make “water flowing” or “gurgling” sounds from refrigerant pressures equalizing when the compressor starts and stops. The noises should discontinue as the refrigerant system equalizes after two or three minutes.
Why does my Gree CAS12HP230V1AC emit fog?
It is normal for your Gree Air Conditioner to emit a slight fog or water vapor when cooling extremely humid warm air. The fog or water vapor will disappear as the system cools and dehumidifies the room space.
Why does my Gree CAS12HP230V1AC make a cracking sound?
It is normal for your Gree Air Conditioner to make “slight cracking” sounds from parts expanding and contracting during system starts and stops. The noises should discontinue as temperature equalizes after two or three minutes.
