Following are some reasons why your ecobee might not be cooling.
1. The thermostat is not set to cool.
This is the most common reason why ecobees are not cooling. To check if the thermostat is set to cool, go to the thermostat’s main screen and make sure that the fan icon is not turned off. You should also make sure that the temperature setting is below the current temperature in the room.
2. The thermostat is not getting power.
If the thermostat is not getting power, it will not be able to turn on the air conditioner. To check if the thermostat is getting power, make sure that the power cord is plugged in and that the circuit breaker is not tripped.
3. The air conditioner is not working properly.
If the thermostat is set to cool and the thermostat is getting power, but the air conditioner is not blowing cold air, the air conditioner itself may be faulty. You may need to contact a qualified HVAC technician to diagnose and repair the air conditioner.
4. The air filter is dirty.
A dirty air filter can restrict airflow and prevent the air conditioner from cooling the room effectively. To check the air filter, remove it from the air handler and inspect it for dirt or debris. If the air filter is dirty, replace it with a new one.
5. The condenser coil is dirty.
The condenser coil is located outside the house and it is responsible for dissipating heat from the refrigerant. If the condenser coil is dirty, it will not be able to dissipate heat effectively and the air conditioner will not be able to cool the room effectively. To clean the condenser coil, you can use a garden hose to spray it off with water. Be sure to turn off the power to the air conditioner before you clean the condenser coil.
6. The refrigerant level is low.
Refrigerant is the substance that absorbs heat from the air in the room and transfers it to the outside air. If the refrigerant level is low, the air conditioner will not be able to cool the room effectively. To check the refrigerant level, you will need to contact a qualified HVAC technician.
7. There is a problem with the thermostat wiring.
If the thermostat wiring is not properly connected, the thermostat may not be able to send the proper signals to the air conditioner. To check the thermostat wiring, you will need to contact a qualified HVAC technician.
8. There is a problem with the air handler.
The air handler is the component of the air conditioning system that blows the cooled air into the house. If there is a problem with the air handler, the air conditioner will not be able to cool the room effectively. To check the air handler, you will need to contact a qualified HVAC technician.
