Outside AC Unit Not Turning On But Inside Is

A split-system AC unit will not work properly unless both the inside and outside systems are operating. This means if the outside unit fails but the inside unit continues to run with the blower fan working, homeowners are still out of luck. Let’s take a look at this issue and what you can do to prevent your AC system from failing.

What To Do When The Outside AC Unit Not Turning On But Inside Is

Your AC system will not cool properly unless both sides of the system are working. If one side of the system is not working correctly, you first need to make sure the AC hasn’t been turned off. In general, there will be a small on-off switch found in a small box near the outside unit that you can check.

Next, check the circuit box in your house, ensuring the breaker for the outside unit hasn’t been tripped. If the breaker has been tripped, turn it all the way off, then flip it back on. If this happens more than one time, it’s time to call the HVAC professionals for help. This could make for a fire and/or safety hazard.

Your thermostat needs to be set to “cool” and the temperature setting should be lower than the room temperature.

Other AC Issues To Consider

When your outside unit breaks down but the inside unit is working, a broken compressor outdoors may be the main culprit. This is a major repair that may even require a complete system replacement.

If the outside condenser/compressor unit is a lost cause at this point, try to resist the temptation to only replace that unit. It’s better to buy an integrated system rather than mixing and matching indoor and outdoor AC units.

If one side of your system ultimately fails, it’s likely a matter of time before the other half stops working. Here are a few other issues that could cause AC failure:

• Electrical issue.
• Coils freezing up.
• Refrigerant line problem.
• Malfunctioning fan in the condenser.
