AC not cooling ? Causes of Inadequate Cooling Performance in Your AC

Summer has arrived, and there’s nothing more stressful than dealing with an air conditioner that is not cooling properly or blowing cold air. Let’s explore the reasons why your AC may not be cooling effectively

Reason for Air conditioner not blowing cold air

Incorrect thermostat settings:

If you notice that your home getting warmer than usual, the first check is the thermostat. Ensure that it’s set to the cooling mode. Verify the temperature setting to make sure it hasn’t been changed. If the thermostat is set to heat, off, or constant fan mode, switch it back to cooling. Wait a few minutes after the system starts and check if cold air is blowing from the registers. If it is, problem solved! If not, move on to the next troubleshooting tip, which is checking the air filter.

Unclean air filter:

Within your AC system, there is typically an air filter situated near indoor air handler unit. This filter serves to trap dirt, dust & other particles, ensuring cleanliness and efficiency of system. However, when the air filter becomes dirty, it can impede airflow and diminish the cooling capability of AC. In more severe cases, a dirty air filter can even cause the system to shut down. If you have verified that the thermostat is functioning correctly and you are still experiencing a lack of cool air, it is important to locate the air filter, switch off the system, and examine it. If the filter is dirty, it should be cleaned or replaced. If your central air conditioner continues to fail in cooling your home adequately, further investigation and troubleshooting are warranted.

Blocked condenser unit:

Your central air conditioning system typically includes an outdoor condenser unit with a coil surrounded by closely spaced metal fins. If your AC is running but not lowering the temperature indoors, it might be due to a blocked or clogged condenser coil. Debris like dirt and grass can accumulate between the fins, impeding airflow. This can result in reduced energy efficiency, insufficient cooling, or even system shutdown.

Damaged heat pump:

In some cases, your outdoor unit might be a heat pump, which can both cool and heat your home. If the heat pump system isn’t cooling, check the thermostat settings, air filter, and condenser unit for any previously mentioned issues. If everything appears fine and you’re still experiencing discomfort, contact your local HVAC dealer for assistance.

Frozen evaporator coil:

The indoor component of your central AC system contains an evaporator coil responsible for removing heat and humidity from the air. If the coil freezes, it can lead to inadequate cooling, higher utility bills, excessive condensate drainage, and even frost formation. Since accessing the evaporator coil is challenging, it’s best to rely on an HVAC professional to address issues related to a frozen coil.

Refrigerant leak:

Refrigerant is crucial for the cooling process, absorbing heat energy from indoor air and releasing it outside. A refrigerant leak can cause your AC system to blow warm air, run for extended periods without effectively cooling your home, or even damage the compressor and result in a complete system shutdown. Checking and resolving refrigerant-related issues should be handled by a qualified HVAC professional.
