Check These Issues To Troubleshoot Your AC System When Starts Causing Problems


Air conditioners are a blessing in the hot summer, but if they break down in the middle of a heatwave, all you can do is wait until it's fixed. Some people have problems with their systems from time to time and need to learn about an air conditioner repair when it breaks down. There are a number of reasons why your air conditioner could be malfunctioning, and here are some things you can check when there's a problem with your system.

Bad Airflow

The first step to troubleshooting your air conditioning system is to check its airflow. Return ducts are connected to the return air plenum, which is located on the floor. The supply duct should be connected to the supply air plenum, which is on the ceiling.

If either the return or supply ducts are leaking air, the airflow will be poor through the air conditioning system. You can figure this out by measuring how much air is coming into the return air plenum. If the amount of air entering the plenum is greater than the amount that should be there, the duct is leaking air. You can check the ducts for leaks by attaching a hose to the return duct and opening it. Another way is to put your hand over the duct vents to see if there is air coming out.

Finally, blocked filters and damaged blower fans can also cause issues. If the system is making noises and there is poor airflow, the blower might need to be repaired or replaced.

Creaky Noises

Creaky noises that start from the bottom or lower end of an air conditioning unit can be a sign of bad bearings or loose bolts. If the sounds are coming from the top end of the unit, it likely means the unit needs to be replaced.

The blower fan can also be the cause of a noisy AC. Often, the problems with a blower might be minor, and a simple repair can stop the noise. Other times, the issues with the blower fan might be due to the motor going bad, which might need to be replaced before the problem affects your home's cooling.

Freezing Up at Low Temperatures

The AC is a central component of the home's cooling system. It powers the evaporator coil that cools the air that circulates through the home. There is a refrigerant inside the evaporator coil. It absorbs heat from the air, which allows it to cool off.

The condenser coil is located outside with the compressor, and these areas are often where problems start. If the AC unit gets too dirty, these components can collect too much condensation and freeze over with ice. You want to clean the unit to prevent these issues before they cause severe damage. Freezing can cause problems with components overheating and your AC system breaking down.

As a homeowner, you should always know about air conditioner repair to keep things going smoothly. Contact an air conditioning repair service to discuss these things for your home.
