What Should I Do When My AC Stops Working? Your Local Guide

There's nothing quite like the sudden silence of a broken air conditioner on a hot summer day. One minute you're enjoying cool comfort, the next, you're facing rising temperatures and a wave of frustration. When your AC system decides to take an unexpected vacation, it can feel overwhelming, but don't panic! Taking a few calm, systematic steps can help you identify the issue or, more importantly, get professional help on the way.

Here’s what you should do when your AC stops working, and how your Aire Serv of Bel Air can help.

Step 1: Check the Obvious (And Safest) Things First

Before you pick up the phone, a quick check of these common culprits can sometimes resolve the issue or provide valuable information:

  • Thermostat Settings: It might sound simple, but is your thermostat set to "Cool" and the temperature set lower than the current room temperature? Sometimes, a family member might have inadvertently changed the settings, or the fan could be set to "On" instead of "Auto," leading to continuous fan operation without cooling.
  • Circuit Breaker: Go to your home’s electrical panel. Look for a tripped breaker labeled "AC," "Furnace," or "HVAC." If you find one, flip it completely off, then firmly back on. Sometimes, a power surge can cause a breaker to trip, interrupting power to your AC unit.
  • Air Filter: A severely clogged air filter can restrict airflow so much that your system might freeze up or shut down as a safety measure. Check your filter; if it's thick with dust and debris, replace it. This is a common issue and an easy fix.
  • Outdoor Unit (Condenser): Ensure the outdoor unit isn't blocked by debris (leaves, grass clippings, etc.) and that the fan is spinning. If the fan isn't spinning, or if the unit is humming loudly but not doing anything, it indicates a problem requiring professional attention. Always exercise caution around the outdoor unit; do not try to fix anything yourself.

Step 2: What If the Obvious Checks Don't Work?

If the above steps don't bring your cool air back, it's time to call in the professionals. Attempting complex repairs on your own can be dangerous and could void warranties. Common issues that require expert attention include:

  • Refrigerant Leaks: If your AC isn't cooling effectively, it might be low on refrigerant due to a leak. This isn't something you can "recharge" yourself; it requires a trained technician to find and repair the leak, then properly recharge the system.
  • Electrical Problems: Beyond a simple tripped breaker, internal wiring issues, capacitor failures, or contactor problems can prevent your AC from turning on or operating correctly. These are best left to licensed HVAC technicians.
  • Frozen Evaporator Coils: If your indoor unit has ice buildup, it's often a symptom of restricted airflow (like a dirty filter) or low refrigerant. The system won't cool properly until the ice melts and the underlying issue is addressed.
  • Blower Motor Issues: If air isn't coming out of your vents, or the airflow is very weak, there might be a problem with your indoor unit's blower motor.
