Central Air Troubleshooting Tips
Posted: August 14, 2023
Why is your Central AC Acting Up?
When your central air conditioning system isn’t working , there could be several reasons for the problem. We understand that it doesn’t always make sense to bring in experts, especially if there’s a simple fix for your AC issue. Read on for some troubleshooting steps you can take before calling in a professional HVAC technician.
DIY AC Troubleshooting
You don’t have to be an HVAC expert to do a little investigating of your central air conditioner’s “health,” so to speak. Start with the following tips:
- Check the thermostat: Ensure that the thermostat is set to “cool” mode and the temperature is set lower than the current room temperature. Sometimes, the issue can be as simple as incorrect thermostat settings.
- Inspect the power supply: Check if the central AC unit is receiving power. Make sure the circuit breaker or fuse for the AC system is not tripped or blown. If it is, reset the breaker or replace the fuse.
- Check the air filter: A clogged or dirty air filter can restrict airflow and cause the system to work inefficiently or shut down. Check the air filter and replace it if it’s dirty. Generally, air filters should be replaced every 1 to 3 months.
- Inspect the outdoor unit: Ensure that the outdoor unit (condenser) is clear of debris, such as leaves, dirt, or grass clippings. A dirty condenser can hinder heat exchange and reduce system efficiency.
- Listen for unusual sounds: If the central air conditioning system is making strange noises, it could indicate a problem. Unusual sounds like grinding, squealing, or banging may signal a malfunctioning component that needs attention.
- Check for airflow issues: Make sure the supply vents in your home are open and unobstructed. Blocked vents can lead to poor airflow and insufficient cooling.
- Inspect the refrigerant lines: Look for any signs of refrigerant leaks around the indoor and outdoor units. Ice buildup on the refrigerant lines can also indicate a potential issue.
- Test the fan: Check if the fan on the outdoor unit is running when the system is supposed to be cooling. If the fan is not working, there may be a problem with the motor or the capacitor.
- Check the condensate drain: Ensure that the condensate drain line is clear and not clogged. A clogged drain can cause water leakage and shut down the system.
If you’ve tried these troubleshooting steps and your central air conditioning system still isn’t working, it’s best to call a licensed HVAC technician to diagnose and fix the issue. Attempting more complex repairs without proper knowledge and tools can potentially cause further damage to the system and may void any existing warranties.
