Five Things To Check When Your AC Is Down

Imagine a scorching, humid summer day. Visible heat waves create thermodynamic mirages on the street as every drop of moisture is evaporated. The blistering heat can only be escaped through a reliable air conditioner. You’re in your home enjoying the cool air until it happens. You hear your air conditioner shut down with a deep mechanical drone. Your home is now an oven in the heat. There’s no worse inconvenience than your air condition giving out when you need it most. If this happened to you, would you be prepared? After reading this, you will be. Here are the five most common causes of an AC shutdown.



The first component to check is your air conditioner’s filter. Over time, air conditioners accumulate dust and particles in their air filters to ensure that the air you breathe is clean. Many models will shut themselves down and not return to operation until the clogged air filter has been cleared of residue or replaced with a new clean one. While this feature may cause inconvenience, it’s actually a great mechanism to ensure that your air conditioner is running smoothly and the air you’re breathing is clean.


Most air conditioners are controlled manually through your thermostat. If the thermostat fails, most AC systems shut down until the thermostat is operational. There are many different types of thermostats so take a look at yours. If you live in an older home, you’re more likely to have an electromechanical thermostat that resembles a dial. Make sure that it’s functional and clean. Electromechanical thermostats are typically connected to your home’s power supply, so if it isn’t working check your circuit breaker or power supply. Newer homes have electronic thermostats that run off of batteries. Regularly test your thermostat to see if the batteries are operational.


Your air conditioner may not be receiving power. Check your breaker of tripped breakers or wiring issues. Flip your breaker off completely before flipping it back on. If you flip the breaker but it continues to trip, don’t restore power yourself. Call a licensed electrician to solve the problem as it may be extremely dangerous.


Check the outdoor condenser for your home AC unit. Sometimes debris such as leaves, grass, dirt, dust, or other particles can clog your unit’s outdoor fan. If this is the case, clear as much debris out of the unit as possible. If this doesn’t work, contact a professional to clear the debris you’re unable to reach.


If none of the above issues are affecting your air conditioner, the problem may be bigger. Air conditioners are complex machines, but the transformer and contractor are two key components that require professional assistance to repair. If you suspect this to be the issue, contact a professional to repair your air conditioner.
