If you own a dual zone air conditioner, chances are you’ve experienced the frustration of one zone not working. It can be incredibly frustrating to have one zone working while the other isn’t, making it difficult to keep your home comfortable. Fortunately, there are some steps you can take to diagnose and fix the issue.
Check the Thermostat
The first step in fixing an issue with your dual zone air conditioner is to check the thermostat. Make sure the thermostat is set at the desired temperature and that the fan is set to the “auto” setting. If the thermostat is not set correctly, the air conditioner will not be able to properly regulate the temperature in each zone.
Check the Air Filters
The air filters in your air conditioner should be checked regularly to ensure they are clean and free of debris. If the air filters are clogged, the air conditioner will not be able to regulate the temperature properly, resulting in one zone not working. To clean the air filters, use a vacuum to remove any dust and debris that may have collected on them.
Check the Air Flow
If the air filters are clean, then you should check the air flow in each zone. Make sure the air vents in each zone are free of obstructions and that the air is flowing freely. If the air flow is restricted, it may be causing one zone to not work properly.
Check the Refrigerant Levels
If the air flow is not restricted and the air filters are clean, you should check the refrigerant levels in your air conditioner. Refrigerant is necessary for the air conditioner to cool the air, and if the levels are low, it may be causing the issue with one zone not working. If you suspect the refrigerant is low, contact a professional to check and refill the refrigerant.
Check for Leaks
If the refrigerant levels are low, it could be because of a leak in the air conditioning system. Leaks can occur in the air ducts, evaporator coils, or condenser coils. To check for a leak, you can use a UV light to look for any signs of leaking refrigerant. If you find a leak, contact a professional to repair it.
Check the Blower Motor
If none of the above steps have resolved the issue, then it may be caused by a faulty blower motor. The blower motor is responsible for circulating the air in your air conditioner, and if it is not working properly, it can cause one zone not to work. To check the blower motor, you should consult the manual for your air conditioner to locate and inspect the motor.
Check the Compressor
If the blower motor is working properly, then the issue may be caused by a faulty compressor. The compressor is responsible for compressing the refrigerant and making it circulate throughout the air conditioner. To check the compressor, you should consult the manual for your air conditioner to locate and inspect the compressor.
