Reasons Why Your AC Suddenly Stopped Working

There are several reasons why an AC unit may stop working. Some of the most common causes include issues with the power supply, problems with the thermostat or control system, low refrigerant levels, dirty or clogged filters and mechanical failures in the compressor or other parts of the system.

One of the first things to check when your AC stops working is the power supply, so be sure the unit is plugged in. You will also want to check that a fuse hasn’t blown, or the circuit breaker has not tripped. If the power supply is not the issue, the problem may be with the thermostat or control system. Sometimes these systems can malfunction, preventing the AC unit from turning on or regulating the temperature properly.

Another common issue that can cause an AC unit to stop working is low refrigerant levels. If the refrigerant levels are too low, the AC unit may not be able to effectively cool the air. This can be caused by leaks in the refrigerant lines or other issues with the system. Call Armstrong to schedule an AC repair. 

Dirty or clogged filters can also cause an AC unit to stop working. If the filters are dirty, they can restrict airflow, making it difficult for the unit to cool the air effectively. This can also put additional strain on the system, leading to mechanical failures over time.

Finally, mechanical failures in the compressor or other parts of the AC unit can also cause it to stop working. These issues may require professional repairs or replacement of the affected parts. For an AC replacement or repair, contact Armstrong Plumbing, Air & Electrical to schedule an appointment with one of our trained technicians or comfort specialists.

Overall, there are many potential reasons why an AC unit may suddenly stop working. Identifying the underlying issue and addressing it promptly can help to prevent further damage to the system and ensure that it continues to function effectively.
