Central air conditioning systems can encounter various issues that hinder their cooling efficiency. When this occurs, your home’s temperature may keep climbing, and your AC might run continuously without cycling off. If you ever face this scenario, follow these steps to diagnose the issue.

Replace the AC Air Filter

The initial step to take when your AC isn’t cooling properly is to replace the AC air filter. Neglecting to change the air filter every one to two months can lead to severe clogging, restricting airflow significantly. Consequently, the blower won’t draw enough warm air into the system, causing your AC to cool slowly or not at all. You can identify this issue easily by the minimal cool air flowing from your vents.

Wait for the Evaporator Coil To Thaw

If hot air is coming from your vents while the AC is running, it’s likely due to a frozen evaporator coil. Several factors can cause this, including a dirty or dusty coil, a clogged air filter, a malfunctioning blower, or low refrigerant levels.

To address this issue, start by turning off your AC to prevent potential damage to the compressor motor. Allow several hours for the coil to thaw completely. You can expedite the process by setting your thermostat’s fan to “On,” ensuring that warm air continues to circulate over the coil.

Before restarting the system, check the air filter for dirt and replace it if necessary. Once you turn the AC back on, monitor its performance to ensure it cools properly. If it starts blowing warm air again, switch it off and contact a technician for a thorough inspection to identify the root cause of the freezing issue.
