6 Steps to Troubleshoot a Non-Working Air Conditioner.

Indiana heat is no joke, it’s important to make sure your air conditioning system is in tip-top shape. If your A/C isn’t working great, Peterman Brothers has you covered with these six easy steps to troubleshoot a non-working air conditioner before calling for professional help.

1. Check your thermostat

It may sound obvious but it’s always good to check to see if it’s set to cool; if not, switch it to cooling mode. If it’s already set to cool and you’re still experiencing issues, move on to the next step.

2. Inspect your air filter

A dirty air filter can significantly reduce airflow, leading to poor cooling performance. If the filter looks dirty, it’s time to replace it. Trust me, a clean air filter can greatly improve your air conditioning performance.

3. Check your breaker or electrical panel

If you still don’t hear the fan running after replacing the air filter, check your panel for a breaker labeled “furnace” or “air handler” and another labeled “air conditioning.” Ensure that neither of the breakers is tripped or in the off position. If the breaker is tripped, it’s time to call for professional service.

4. Check the insulated lines

If you hear the fan running, inspect the two black foam insulated lines. If you notice ice on the lines, turn off the thermostat so that the unit can thaw, and schedule a service call. The presence of ice could indicate a refrigerant issue or other technical problems that need to be addressed by a professional.

5. Check the condensing unit

Verify that the unit is running and the fan is blowing warm air from the top. Ensure that the coils are clean and not blocked by grass or cottonwood. If you notice any obstructions or clogging, it’s time to schedule a service appointment.

6. Temper expectations

Remember that air conditioning systems are designed to dehumidify and cool homes based on their size and the average temperature in the region. During extremely hot days, your home may not get below a specific temperature, such as 75 degrees, even when the air conditioner is running correctly. It’s important to manage your expectations accordingly.
