What causes air conditioner to stop working?
If your air conditioner suddenly stops working, it can be a frustrating and uncomfortable experience. However, there are several common reasons why an air conditioner might stop functioning, and understanding these causes can help you address the issue more effectively.
Clogged Air Filters
One of the most common reasons for an air conditioner to stop working is a clogged air filter. Over time, the filter can become blocked with dust, dirt, and other debris, which can restrict airflow and cause the system to work harder, leading to a breakdown. Regularly cleaning or replacing the air filter can help prevent this issue.
Refrigerant Leaks
Another common problem is a refrigerant leak. Refrigerant is the substance that allows the air conditioner to cool the air, and if there is a leak, the system will not be able to function properly. Refrigerant leaks can be caused by a variety of factors, including wear and tear, damage to the system, or improper installation.
Electrical Issues
Electrical problems can also cause an air conditioner to stop working. This could be due to a faulty thermostat, a tripped circuit breaker, or a problem with the wiring or electrical components of the system. If you suspect an electrical issue, it's best to have a professional technician inspect the system.
Compressor Failure
The compressor is a critical component of an air conditioning system, and if it fails, the entire system will stop working. Compressor failure can be caused by a variety of factors, including age, wear and tear, or a lack of maintenance.
Frozen Coils
In some cases, the air conditioner's coils can become frozen, which can prevent the system from cooling the air effectively. This can be caused by a variety of factors, including low refrigerant levels, a blocked air filter, or a problem with the blower fan.
If your air conditioner stops working, it's important to diagnose the problem as soon as possible to prevent further damage and ensure that your home remains comfortable. If you're unsure of the cause, it's best to contact a professional HVAC technician who can inspect the system and provide the necessary repairs.

How many years does Freon last in a air conditioner?
around 10-15 years
Generally speaking, a properly maintained air conditioner can expect its refrigerant to last around 10-15 years or longer—depending on usage frequency and environmental wear and tear. To ensure your refrigerant lasts as long as possible, regular maintenance is key.
What is the first thing to check when the AC stops working?
Make sure it has power (check outlet if a window unit, check circuit breaker if hardwired). Check thermostat battery if accessible (some wall units use a battery). Check if filters are clogged. Check outside duct for obstructions.
Where is the AC reset button located?
In AC systems, the air conditioner reset button is on the outside unit's lower edge, typically close to the ground. Some models have the reset button located behind the service panel, which may require tools to remove. Reset buttons are usually red or yellow with a clear “reset” label.
