Troubleshooting Tips for a Central AC Not Turning On

When a homeowner cannot get the central AC to turn on, there are certain troubleshooting steps that can be taken to attempt to resolve the issue. In some cases, the problem is minor and can be quickly addressed; however, in other cases, professional service may be needed to repair or replace a broken component of the system. The following troubleshooting tips can be useful in figuring out the cause of a central AC not turning on.

Checking the Thermostat

The first step to take when troubleshooting the AC unit is to check the thermostat. Start by ensuring that the thermostat is powered, either installed on batteries or plugged into the wall. Next, check the temperature reading. If it reads too low, set it to a higher temperature, and allow the AC unit to kick back on.

If the thermostat is not the issue, then the problem could be with the main power switch. Ensure that the switch is turned on and that the outlet is providing power. If the switch was off, or if the plug or cord leading to the power source was not correctly plugged in, the AC unit will not have power.

Checking the Circuit Breaker

The next step is to check the circuit breaker. Look for a breaker switch in the panel with the label “Air Conditioner”, and if you find it in the tripped position, switch it back on. If this does not work, try resetting the circuit breaker for the whole house, as flicking the switch may just trip it again.

It is possible that a wiring issue is causing the breaker to trip, in which case, a licensed electrician is needed to repair the wiring. In addition, if the breaker trips again and again, this could be an indication that the AC unit is receiving too much power, and professional help may be required.

Checking the Filters and Condenser

Next, open up the access panel of the outdoor condenser unit, and check the condition of the air filters. If they have not been changed recently, they could be clogged, and they must be checked or changed to restore optimal performance.

In addition, check that the condenser fan is running properly and that there is no visible damage to blades or electrical wires. If something appears off with the fan blades or wiring, contact a professional HVAC technician to make the necessary repairs.

In conclusion, when a home AC unit is not turning on, there are several troubleshooting steps that can be taken, such as examining the thermostat, checking the circuit breaker, and inspecting the air filters and the condenser fan. If the homeowner cannot locate the source of the issue or is unsure how to proceed in making repairs, it is essential to contact an HVAC professional for assistance.
