3 Signs That You May Need Air Conditioning Repairs

Do you need San Bernardino AC repair? If you suspect a malfunction, delaying service will give the problem time to worsen. You might face the loss of your cooling system or significantly higher repair costs.


In many cases, a problem that seems serious has a simple solution. If you’re experiencing any of these AC problems, you should call for repairs.


1. The Air Coming From Your Ducts Feels Warm

There are several reasons you might feel warm air coming from your ducts. The simplest and most common reason is duct damage. A gap or tear in your ducts might let warm air inside, causing your treated air to absorb heat.


Alternatively, dirty coils or a refrigerant leak can cause poor cooling. If you see frozen or icy coils, schedule professional coil cleaning. Otherwise, listen for a gurgling sound to isolate a leak. Any of these problems requires professional HVAC repairs.


2. You Notice Low or Reduced Airflow 

Duct damage is a cause of reduced airflow as well. If you can rule out a duct issue, you'll need San Bernardino AC repair. The second most common cause is a malfunction with the blower fan assembly. The motor might need lubricating, or you might have a worn belt. In rare cases, a damaged or loose fan is causing the problem.


3. The Air Conditioner Won't Run a Cycle

If your air conditioner isn't working at all, you have a more serious issue. You might have a wiring short that's keeping your thermostat from communicating with your HVAC system. In that case, an HVAC technician will replace the affected wires and restore the connection.


Another possibility is a failed capacitor. If the start or run capacitors failed, the system won't work. Your technician can determine which capacitors failed. They can also replace worn-out capacitors for you.
