There could be a few reasons why your AC is not working after changing the batteries in the thermostat. It's possible that the thermostat settings need to be adjusted or that there is a problem with the AC unit itself. It's best to check the thermostat settings and make sure they are correct, and if the issue persists, you may need to contact a professional to inspect the AC unit.
can a faluty thermostat affect your central ac working?
Yes, low batteries will affect your furnace/AC operation. Change the batteries to correct the issue.
The AC will start working effectively immediately after changing the air filter.
Probably not, but it's almost certainly one of the cheapest things you can try to see if it helps.
If your thermostat doesn't have batteries, it may be hardwired into your HVAC system. Check the circuit breaker to ensure it hasn't tripped. If the circuit breaker is fine, there might be an issue with the wiring or the thermostat itself. Calling a professional HVAC technician would be the best course of action to diagnose and fix the problem.
The upstairs AC may not be working due to issues with the ductwork, thermostat settings, or a malfunction in the unit itself. It is important to check these factors to determine the cause of the problem.
To replace an AC thermostat, first turn off the power to the unit. Remove the old thermostat cover and disconnect the wires. Install the new thermostat according to the manufacturer's instructions, making sure to connect the wires correctly. Finally, turn the power back on and test the new thermostat to ensure it is working properly.
Your AC may freeze due to restricted airflow, low refrigerant levels, or a malfunctioning thermostat. To prevent it, ensure proper airflow by changing filters regularly, have your system serviced annually, and keep the thermostat at a consistent temperature.

To connect thermostat wires to an AC unit, first turn off the power to the unit. Then, match the wire colors from the thermostat to the corresponding terminals on the AC unit. Typically, the wires are connected to terminals labeled R, Y, G, and W. Use a screwdriver to secure the wires in place. Finally, turn the power back on and test the thermostat to ensure it is working properly.
The purpose of the thermostat wires outside the AC unit is to connect the thermostat inside the building to the AC unit outside, allowing the thermostat to communicate with the AC unit and control its operation based on the desired temperature settings.
