How to Troubleshoot Your AC Unit Before Calling an AC Repair Company in Bowie

AC Troubleshooting Tips

If your home isn’t staying cool, you may wonder what is the first thing to check when the AC stops working. Before calling our AC repair company in Bowie, MD, try these troubleshooting steps to see if you can resolve the issue on your own. Some problems have simple fixes that can restore your cooling system in minutes.

1. Check the Thermostat

Your thermostat controls when and how your air conditioner runs. If your AC isn’t turning on or isn’t cooling properly, start here:

• Make sure it’s set to “Cool” mode, not just “Fan” or “Heat.”
• Lower the temperature a few degrees to see if the system responds.
• If your thermostat is battery-operated, try replacing the batteries.
• Check the screen—if it’s blank, it may need new batteries or have a wiring issue.

2. Inspect the Air Filter

A clogged air filter can restrict airflow, making it seem like your AC isn’t working properly.

• Locate the air filter (usually near the return vent or inside the air handler).
• If it looks dirty or clogged, replace it with a new one.
• Regularly changing your filter (every 1-3 months) can prevent AC issues in the future.

3. Check the Circuit Breaker

If your AC isn’t turning on at all, it could be a power issue.

• Find your home’s electrical panel and look for the breaker labeled “AC” or “HVAC.”
• If the breaker is tripped, reset it by flipping it off and then back on.
• If the breaker trips again immediately, there may be an electrical issue that requires professional attention.

4. Inspect the Outdoor Unit

Your outdoor AC unit (condenser) needs proper airflow to work efficiently.

• Remove any debris, such as leaves or dirt, that may be blocking the unit.
• Make sure there’s at least 2 feet of clearance around the unit for proper ventilation.
• If the unit isn’t running, listen for any unusual sounds—buzzing or clicking noises could indicate an electrical issue.

5. Check If the AC Fuses Are Blown

Your AC unit may not be getting power due to a blown fuse in the disconnect box (usually located near the outdoor condenser unit).

• Turn off the power to the AC system at the breaker panel.
• Open the disconnect box and look for fuses (they may be cartridge-style).
• Use a multimeter to test—if the reading is zero, the fuse is blown and needs to be replaced.
• If you’re unsure or uncomfortable handling electrical components, it’s best to call a professional.

6. Look for Frozen Evaporator Coils

If your AC is running but not cooling, the evaporator coils inside your indoor unit may be frozen.

• Turn off the system and check for ice buildup on the coils.
• If you see ice, let the system thaw completely before turning it back on (this can take a few hours).
• A frozen coil is often caused by low refrigerant levels, which requires a professional repair.

7. Make Sure the Condensate Drain Isn’t Clogged

Your AC produces condensation that drains away through a small pipe. If this line gets clogged, it can cause your system to shut down.

• Locate the drain line near the indoor air handler.
• If you see standing water or moisture, the line may be clogged with dirt or algae.
• Use a wet/dry vacuum or pour a mixture of vinegar and water down the drain to clear the blockage.

8. Check the Air Vents

Blocked or closed vents can prevent cool air from circulating properly.

• Walk around your home and make sure all supply and return vents are fully open.
• Move any furniture or curtains that could be blocking airflow.

Should I Turn Off the AC If It’s Not Cooling?

Yes, if your AC is running but not cooling after you’ve tried these troubleshooting steps, it’s best to turn it off to prevent further damage. When an air conditioner struggles to cool, it could be due to issues like a frozen evaporator coil, low refrigerant levels, or restricted airflow. Continuing to run the system in this condition can put unnecessary strain on the compressor, which is one of the most expensive components to replace. Turning off the AC unit prevents the system from overworking itself.
