Sudden AC Failure
6 Most Likely Reasons Why Your AC Is Not Working
Air conditioning issues are always troublesome to deal with but become even more of a nuisance on a hot summer day when you need AC the most. In the valley and southern California during the summer it can get to be in the triple digits, on these days you definitely need your AC working. However, no matter what condition your unit is in there is always a small chance it can face sudden ac failure. Usually when an air conditioner stops working there is always a reason why. Below we discuss some common reasons for sudden ac failure.
Thermostat Malfunction
If you are suffering from sudden ac failure the first thing to check is your thermostat. Check your thermostat to see if it is on. If your thermostat has stopped working then your air conditioner will not turn on, even if there are no issues with the ac itself. Check that the thermostat is set to the right temperature and cool setting. It may also be that your thermostat needs new batteries or needs a repair. The thermostat controls the HVAC system, and it is important to keep it in good working condition. The thermostat is not always the reason for sudden ac failure, but you should always check it first.
Tripped Breaker
If your thermostat is not the culprit for your sudden ac failure, check your circuit box to see if a breaker tripped. Switch the breaker back on and try to turn your AC on again. A tripped breaker can be caused by electrical problems in the home or from an AC overheating.
AC Unit is in “OFF” mode
Depending on the type of unit you have, your system may be in the off mode. If any of the switches were turned off by accident, then your ac will not turn on. It could be the emergency shutoff switch which is located near the condenser unit. Try to turn it to the on position and test your ac again.
Clogged Air Filter
Your ac requires unrestricted air flow. If you hear your ac turn on, but are not receiving any cool air, a clogged filter could be the culprit. Dirty clogged air filters could also be the cause for overheating leading to a tripped breaker mentioned above. Air filters work by capturing dirt, dust and other particles from entering your HVAC system. If not replaced, air filters can become clogged restricting airflow and reducing efficacy. Consult your manual to learn more about the type of filter your system requires. Check your air filter at least once a month and replace as needed.
Dirty Condenser
Another issue that could lead to restricted air flow is a dirty condenser. The condenser is the part of the system that is outdoors. As the condenser sucks in air to cool it can bring in outdoor debris such as leaves and other foliage. Turn off the power to the condenser and check if there is any blockage. Inside your home also check your vents and grilles. Removing anything that may be causing restricted airflow may solve the issue.
Lack of Maintenance
Lack of routine maintenance could also lead to sudden ac failure. Routine maintenance can help minimize the need for unexpected or costly repairs on a day when you need your ac the most. The manufacturer of the system will have guidelines for you to follow, but we recommend maintenance at least once every 6 months.
