What to Do If Your Air Conditioning System Won’t Turn On

Certain summer days seem custom-made for central air conditioning systems: those scorching hot days when the relentless sun is matched only by the oppressive humidity in the air. These are the days when flipping the “on” switch feels like a relief, knowing that refreshing cool air will soon alleviate the discomfort of overheating.

However, what happens when the air conditioner refuses to cooperate, leaving you sweating not from the heat, but from the anxiety of a malfunctioning system? If you haven’t experienced this scenario yet, this summer might mark the end of your luck, especially if your air conditioner is over a decade old and nearing the end of its expected lifespan.

Here are four simple troubleshooting steps to try:

  1. Check Your Thermostat: Sometimes, adjusting the thermostat temperature slightly lower can kick-start the air conditioner. If the thermostat needs calibration or replacement, it’s a relatively straightforward fix.
  2. Inspect Your Filter: A clogged filter can cause the air conditioner to shut down. Replace the dirty filter with a clean one to restore proper airflow.
  3. Inspect the Circuit Breaker: Ensure that the circuit breaker for the air conditioner is in the “on” position. If it has tripped, resetting it may resolve the issue. However, repeated tripping could indicate an overload or underlying electrical problem.
  4. Clear the Area Around the Outdoor Unit: Remove any debris, grass, or shrubs obstructing the outdoor unit. Maintain a clearance zone of 2 feet around the unit and 8 feet above it to promote adequate airflow.

If these steps don’t resolve the issue, it’s time to enlist the help of Experts In Your Home for a professional diagnosis. Possible reasons for a non-responsive air conditioning system include compressor or motor issues, refrigerant leaks, icy buildup on condenser coils, or wiring problems.

Regular maintenance checks are essential to prevent breakdowns caused by dirt and neglect, which can significantly reduce the system’s lifespan. Remember, according to the U.S. Department of Energy, if repair costs exceed 50 percent of the system’s value, replacing the system may be more cost-effective in the long run.
