1. AC Won’t Turn On

If your air conditioner isn’t powering on, here are a few possible causes:

• Tripped Circuit Breaker:
  Check your electrical panel for a tripped breaker labeled “AC.” Flip it back to the “on” position. If it trips again, don’t attempt further resets—this could indicate an electrical problem.

• Incorrect Thermostat Settings:
  Make sure your thermostat is set to “cool” and the temperature is lower than the current room temperature. Replace batteries or reset your thermostat if needed.

• Shut-Off Switch:
  Locate the external shut-off switch near your outdoor unit. Ensure it’s in the “on” position.

• Overflowing Condensate Drain Pan:
  If your drain pan is full, clear it and check for blockages in the drain line.

2. AC Blows Warm Air

When your system is running but isn’t cooling, airflow or refrigerant levels may be the issue:

• Blocked Air Filter:
  Replace a clogged air filter to restore airflow and prevent strain on your system. Filters should be changed every 1–3 months.

• Dirty Condenser Coils:
  Clear debris from your outdoor unit and gently clean the fins with a hose. This ensures proper heat dissipation.

• Low Refrigerant Levels:
  Signs of refrigerant leaks include longer cooling cycles, weak airflow, and frost on the evaporator coil. Call a professional to locate and fix leaks, then refill refrigerant to the proper level.

3. AC Not Blowing Enough Air

If your air conditioner isn’t circulating enough cool air, consider the following:

• Dirty Air Filter:
  A clogged filter restricts airflow, reducing system efficiency. Replace it if necessary.

• Blocked or Disconnected Ductwork:
  Inspect visible ductwork for blockages or disconnections. A professional inspection may be needed for hard-to-reach areas like attics or crawl spaces.

• Fan or Motor Issues:
  If your fan isn’t running, the motor or capacitor may need repair or replacement.
