As the locals of Las Vegas and surrounding areas continue into the summer months, we are very reliant on the air conditioner to keep us comfortable. When the air conditioner does not respond to flipping it on, there could be a host of reasons as to why. There are a few things you can check before you call a pro in. Today, we at Air Supply Heating & Air Conditioning would like to share a few things you can do to power on the air conditioner.
Troubleshooting AC Not Turning On
1) Check thermostat settings. Make certain to program desired temperature on the thermostat is lower than the current room temperature and ensure it is set to “cool.” Also, look to see if the fan is set to “auto” or “on.” The fan will only run when the air conditioner is cooling air it’s on “auto.” Even if the AC isn’t cooling air, the on” setting tells the fan to run continuously. If the thermostat has no display, the batteries may be dead, and it needs replacing.
2) Inspect circuit breaker panel. Through their electrical circuits, air conditioning systems draw a lot of power. This can cause the circuit’s circuit breaker to trip and stop electricity from flowing through the circuit if a brief power surge happens. Your AC can’t turn on when that happens. It will switch from the “on” position to the “off” position if a circuit breaker has tripped. By flipping them back to the “on” position, you can reset any tripped breakers.
3) Ensure HVAC system’s power is switched on. With most central air conditioners, there are two power switches associated. The indoor unit is powered with one switch, and the outdoor unit is powered with another. For your AC to work, both switches need to be in the “on” position. Generally, you can find the switch for the indoor unit near your system’s furnace or air handler. Usually in a metal box on the exterior of your home, you can find the switch for the outdoor unit next to the outdoor unit.
4) Check air filter. Your AC is strained and making it more likely to overheat and shut when a dirty air filter can restrict airflow. At least once every three months during the cooling season is when most homeowners should replace their air filters. However, in the Vegas Desert, you should change it more often. Replace the filters if you don’t know when you last replaced your air filter, or if it looks visibly dirty. It is ideal to have several filters on hand so you can change them as needed.
5) Check for clearance around outdoor AC condenser unit. Causing your AC to overheat and turn off can come from landscaping, loose leaves, dirt, and miscellaneous debris can block airflow through the outdoor unit. Ensure there is at least two feet of clearance around the unit and several feet of vertical clearance and remove any debris blocking airflow. They need plenty of overhead room to breathe since outdoor AC units usually release the most heat from the top.
6) Try resetting the unit if you know how. After a power surge trips the circuit breaker, your air conditioner might start acting strangely. Sometimes all it needs is a hard reset. To avoid inadvertently creating more problems, look over your system’s owner’s manual for specific instructions on how to correctly reset your particular system.
