Gibson Central air conditioner has poor temperature control
If your Gibson central air conditioner has poor temperature control, uneven cooling, or temperature swings, start with the air filter. A dirty or clogged air filter restricts airflow through the furnace or air handler, reduces cooling capacity, and can cause the evaporator coil to frost over. Replace the filter at least twice a year, or more often in dusty homes or homes with pets. Next, check the wall thermostat. Failed electrical contacts can make the condensing unit or air handler operate intermittently, preventing the AC from holding the set temperature. A qualified DIYer can test the thermostat for continuity with a multimeter and replace it if defective. Blocked or leaking vents are another possible cause because poor duct airflow can leave some rooms too warm. Finally, an oversized air conditioner may cool quickly and shut off before air circulates evenly. Enter your model number to find the exact air filter, thermostat, or other replacement part for your Gibson central air conditioner. If these checks do not correct the problem, have a licensed HVAC technician inspect the system. Refrigerant or sealed-system repairs require EPA 608 certification, and 240-volt components should not be serviced unless you are qualified.
01 - Gibson Central Air Conditioner Air Filter
Check and replace the air filter at least twice a year, more often in dusty/dirty environments or if there is a pet in the home. A clogged air filter will greatly reduce the air flow of the furnace or air handler which can result in poor temperature control when trying to heat or cool the home.

Highly Likely
02 - Gibson Central Air Conditioner Wall Thermostat
The wall thermostat has electrical contacts that control the power supply to the furnace or air handler and condensing unit. If the contacts in the thermostat fail, certain components of the cooling system may not work or may only work intermittently. To determine if the thermostat is defective, use a multimeter to test it for continuity. If the wall thermostat does not show proper continuity, replace it.
Common
03 - Gibson Central Air Conditioner Wifi Thermostat
The WiFi thermostat has electrical contacts that control the power supply to the furnace or air handler and condensing unit . If the contacts in the thermostat fail, certain components of the cooling system may not work or may only work intermittently. To determine if the thermostat is defective, use a multimeter to test it for continuity. If the WiFi thermostat does not show proper continuity, replace it.
Common
04 - Clogged Air Filter
If the air filter is clogged, air cannot flow properly through the home's venting system. This greatly reduces the cooling capacity of the air conditioner. In addition, if the air filter is clogged, the evaporator coils will frost over and not be able to remove moisture from the air. The air filter should be checked and replaced at least twice a year, more often in dusty/dirty environments. Refer to owner's manual for guidance.
Less Common
05 - Blocked or leaking vents
The furnace or air handler must have good airflow to work properly. A blocked or leaking vent can prevent good air flow and cause inconsistent room temperatures.
Less Common
06 - Oversized air conditioner
An oversized furnace or air handler will quickly heat or cool the home and shut off. This causes acceptable temperatures in certain areas but not in others. The circulated air needs time to distribute evenly throughout the home; the air recirculating through the furnace or air handler for longer periods of time will produce better results.
