When your AC won’t turn on, it often happens at the worst possible time, such as the first hot day of spring or the hottest day of the year. However, don’t panic as it’s usually easily fixable. Here are some DIY steps you can take to start your AC unit without paying for professional services:

  1. Check the thermostat and circuit breaker: Sometimes, the issue is as simple as a thermostat or circuit breaker problem. Ensure that your thermostat is set to the right temperature, and its batteries are not dead. Also, check if the circuit breaker has tripped.
  2. Check if your AC has a switch: Some AC models have an ON/OFF switch that could be mistakenly flipped.
  3. Check your air filter: Dirty air filters can cause airflow issues, leading to AC problems. Replace your air filters every three months.
  4. Check your drain pan: Drain pan issues such as being full, rusted through, or clogged can cause AC problems. Locate the drain pan and inspect it for issues.

If the above DIY fixes don’t work, it may be time to contact a professional. Some professional fixes for an AC unit that won’t turn on include blown fuse replacement, capacitor replacement, circuit board replacement, compressor replacement, condensate pump replacement, evaporator coil replacement, fan motor replacement, refrigerant leak diagnostic, and thermostat replacement.
