uneven temperatures in your home

A functional and efficient air conditioner provides a constant supply of cold air in your home. However, when the AC starts to fail, you might notice a marked decrease in the amount of cold air blowing into the house. It is advisable to have a technician check the system and figure out what could be wrong. Here are some of the common reasons why air conditioner units stop blowing air and how to deal with them. 

Your Air Filters Might Be Clogged

One of the main reasons you might be experiencing a reduction in the amount of air flowing through your AC is clogs in the air filters. Generally, an AC unit breathes in through the return vents. When the return vents get clogged, the amount of air that can get inside the air cooling system is reduced. When the filters accumulate dirt from the house, they lose their ability to draw in air. Therefore, the first place to check is the vents. If the filters are clogged, consider replacing them. 

Evaporator Coil of Your AC Could Be Frozen

An evaporator coil is an integral part of your AC that cools down the warm air returning from the room. The warm air first gets filtered by the filter. Then, it passes over the coil. The refrigerant inside the coils absorbs the heat and evaporates. When the coil is frozen, air cannot pass through to the duct system. The blockage weakens the overall airflow in your home. Also, the coil can freeze because of dirt and leaking refrigerant. An AC professional should check the state of your evaporator coils. If they have ice on them, a professional will know how to resolve the problem and restore the airflow. 

Your AC Blower Is Damaged

A damaged AC blower is another common reason why the cold air in your room might decrease. Some issues include excessive dirt and debris on the blower fans. Your blower motor might also be damaged. The blower motor powers the unit and makes it rotate, blowing the cold air back into the vents and into the room. When the motor is damaged, it will not set the fan in motion efficiently, which will minimize the supply of cold air inside your home. 

These are some common reasons why the flow of cold air might decrease inside your home. It is advisable to hire an air conditioning repair technician to check your unit and ensure it is functional. They will fix any part that is malfunctioning and restore your AC efficiency.
