What is what to do when ac goes out?

Here's what to do when your AC goes out:

First, don't panic! Assess the situation calmly.

  1. Check the Basics:

    • Is the AC unit turned on? Sounds obvious, but it's easily overlooked.
    • Is your thermostat set correctly? Make sure it's on "cool" and the temperature is set below the current room temperature.
    • Check the circuit breaker. A tripped breaker is a common cause. Go to your electrical panel and check the breaker labeled for the AC. If it's tripped (in the middle position), flip it all the way off and then back on.
  2. Check the Air Filter:

    • A clogged air filter can restrict airflow and cause the AC to malfunction or freeze up. Replace your air filter regularly. This is good preventative maintenance, but especially important when troubleshooting a problem.
  3. Check the Outdoor Unit:

    • Make sure the outdoor unit (condenser) isn't blocked by debris like leaves, branches, or snow. Clear away anything obstructing airflow around the unit.
    • If the unit is frozen, it means there is problem with airflow or refrigerant. Let it thaw for at least one or two hours.
  4. Listen for Unusual Noises:

    • Unusual noises like banging, grinding, or hissing could indicate a mechanical problem. Note what you hear to tell the repair technician.
  5. If it Restarts:

  • After performing all the checks, if the unit restarts monitor it for a couple of hours. If it stops again, call a professional.
  1. Call a Professional:
    • If you've checked all the basics and the AC still isn't working, it's time to call a qualified HVAC technician. Don't attempt to repair complex AC problems yourself, as you could cause further damage or injure yourself. Look for licensed and insured technicians.
