Nothing is more annoying than having a broken air conditioner on a hot summer day. You should try several simple things to see if you can solve or diagnose the problem yourself, though, before you pick up the phone to spend hard-earned money on a potentially unnecessary service call. Remember that you cannot resolve all potential issues. Playing around with your AC’s electrical wiring is unsafe, and opening the AC system up might only worsen the issue. Air conditioner repair is the key.  

You may have overloaded the circuit if too many electronics are hooked in and operating. This is particularly likely if you have several fans on a warm summer day. If the circuit breaker is properly installed or put in the off position, check your fuse box to be sure and turn it back on. If everything else stopped working simultaneously, you might just be experiencing a power outage. 

Check your thermostat to determine whether it is set to “auto” or “automatic” if your air conditioner frequently turns on and off. If so, this is why your air conditioner keeps turning off. When on auto, the air conditioning system won’t operate until the temperature has increased over the setting on your thermostat. When heating or cooling your home, you were keeping the thermostat set to “auto” is far more effective. However, feel free to adjust the thermostat if it isn’t warm or cool enough for you. 

Consult your owner’s handbook. Most of the time, the cover has a small lip that may be easily removed by hand. Try changing the old batteries in your remote control or the thermostat and closing the lid to see if that fixes the issue. You won’t be able to manage it or care for any electrical problems alone. Call an HVAC or electrician to get someone to look at the issue. 

Approximately every three months, your filter needs to be changed. You might have to swap it out every month in the summer. Replace the filter if you have an issue with your AC unit and haven’t done so in a while. You don’t need to call anyone if the issue solves itself. You’ll probably need to contact an HVAC specialist if the issue continues. 

The filter on a central air conditioning system is often found on the furnace or in the ductwork on the return line. The condenser outside of a ductless system has a reusable filter. The filter is often located behind the grates in front of a window unit. 

The proper operation of your system may be hampered if there are any blockages in front of the vents or ducts. Verify that all of your vents and ducts are open and free of obstructions by taking a walk around your house. Rearrange your furniture if necessary to make sure that everything is accessible. Remove any dirt that may be around your condenser unit if it is present outside. This might occasionally be the problem’s root cause.
