Split-system AC units cannot function properly without both the inside and outside systems working. This means if the outside unit fails but the inside one continues to run, you are still out of luck as a homeowner. Let’s go into detail on this issue and see what you can do to prevent the outside unit from failing.
What To Do When Outside AC Is Not Turning On But Inside Is
As mentioned, both inside and outside units need to work for your AC system to function. The first step is to make sure the AC hasn’t been turned off before determining the system is not working correctly. Typically, there will be a small “ON-OFF” switch located in a small box nearby the outside unit.
The next step is to check the circuit box in your home, making sure the breaker for the outside system hasn’t been tripped. If the breaker is tripped, turn it off entirely, then flip it back on. Call the HVAC professionals if this happens more than once. This can make for a safety and/or fire hazard.
The thermostat should be set to “cool”, and the temperature setting needs to be lower than the room temperature, at this time.
Other AC Unit Issues
Generally, a broken compressor outside is the main culprit behind this issue. This is a major repair that could eventually require a complete unit replacement.
If the outside condenser/compressor unit is a lost cause, refrain from only replacing that specific unit. It’s best to purchase an integrated system rather than mixing and matching units inside and outside.
It’s likely just a matter of time before both sides fail once one side is not working. Here are a few other AC issues that could cause the unit to fail:
- Refrigerant line issue.
- Electrical problem.
- Coil freezing up.
- Malfunctioning condenser fan.
How To Take Care Of Inside And Outside AC Units
Keeping up with routine maintenance needs is the simplest and best way to prevent any issues. DIY tasks like cleaning the vents and registers can go a long way. Investing in professional maintenance annually will help keep your AC running for as long as possible.
