Before you do anything else, make sure you turn off the breaker for your air conditioner. This will prevent it from accidentally coming back on while you’re working on the system. If you have a central air system, you’ll turn off the breaker for the main unit. If you have a window unit, you’ll turn off the breaker for the circuit that powers that unit.
If you still have power, but your air conditioner isn’t working, check to see if a breaker has tripped. If it has, you’ll need to turn it back on. If a breaker has tripped, it will stay tripped until someone turns it back on. This is a safety feature that prevents you from accidentally plugging appliances into a live circuit. If a breaker has tripped, it’s best to turn it back on by turning the main breaker off and then back on again.
If your power has been out for longer than a few minutes, it’s possible that a fuse has been blown. To check for a blown fuse, turn off the breaker and then look at the fuse box. Fuses for your air conditioner are often found in the garage or near the circuit panel. If a fuse has been blown, you’ll need to replace it before the breaker can be turned back on.
If the breaker is off and the fuse hasn’t been blown, you’ll need to call for help. You can call your utility company or a local HVAC company. If you’re renting and the landlord doesn’t have a maintenance person on call, you can call a 24-hour HVAC repair company. Once you’ve called for help, you can proceed with the rest of the instructions.
If an air filter has been in place for more than a few hours, it’s a good idea to change it. If a filter has been in place for longer than a week, it should be replaced. An old filter can make it harder for your air conditioner to cool your home. This can be especially problematic if you have a central air system. If you use a window unit, you can usually change the filter without affecting the unit’s performance.
If your air conditioner isn’t working, the first thing you should check is the thermostat. You can check the thermostat by removing the cover and looking at the numbers. If the thermostat is set to a higher temperature, it may not have shut off the air conditioner. If the thermostat is set to a lower temperature, it may have shut off the air conditioner before it reached the desired temperature.
If the thermostat is set to the correct temperature, but the air conditioner isn’t working, you may need to change out the wires. First, make sure that the breaker is off. Then, use a pair of insulated pliers to remove the wires from the thermostat. Try to pull them out in the same direction they are connected to the thermostat. If the wires are connected correctly, you can use a pair of wire connectors to reattach the wires to the thermostat. If the wires aren’t connected correctly, you may need to call a professional to reconnect them.
If the thermostat is set correctly and the air conditioner is still not working, you may need to check the compressor. Compressors for air conditioners are large, heavy, and can be difficult to remove. You can try to remove the compressor yourself, but it’s best to call a professional if you aren’t sure how to do it. If the compressor is not the problem, you may need to replace the fan or fan speed control. If the fan or fan speed control is not the problem, you may need to replace the air filter. If none of these parts is the problem, you may need to replace the entire unit.
When your air conditioner breaks down unexpectedly, it can be frustrating. However, it’s important to know what to do in these situations. If your air conditioner breaks down, the best thing to do is turn off the breaker, check for a tripped breaker, check for a blown fuse, and then call for help. If the breaker is off and the fuse hasn’t been blown, you’ll need to change the air filter, change the wires, and check the thermostat. If the thermostat is set to the correct temperature, but the air conditioner isn’t working, you may need to change out the wires, check the compressor, and check the fan or fan speed control. If none of these parts is the problem, you may need to replace the entire unit.
