When Your Air Conditioner Won't Work

5 Reasons For Central Air Conditioner Inefficiency

17 May 2016 by Clara Fernandez

Are you puzzled as to why your central air conditioning system has to be on for a long time before your house reaches a desirable temperature? Numerous things can go wrong with a central air conditioning system that causes inefficiency. Below, you will discover a list of some of the possible problems that a central air conditioning system might have that leads to inefficient cooling.

Air Leaks Out of the Ventilation System

A leakage of air is one of the possible reasons your house has been taking a long time to cool down. Basically, there might be holes or cracks in the air ducts that need to be sealed up. You might even need to get the air ducts replaced altogether. The air duct fittings can also be loose and allowing air to leak out.

The Thermostat Is Damaged

It is possible that you are not setting the thermostat to the temperature that you think. If you have an old thermostat, it might be damaged and does not show the correct temperature setting. For instance, the needle may be broken and does not move to the correct temperature setting. You might think that the temperature is set to be lower, but it actually is not because of the malfunctioning needle.

More Refrigerant Is Needed in the System

A central air conditioning system must have a sufficient amount of refrigerant to cool down a house. The system must also have water in it that can be mixed with the refrigerant. The water and refrigerant basically mixes together in the system and is transformed to gas that cools down the evaporator coil. The evaporator coil must be cold enough to cool down the warm air that passes through it.

The Evaporator Coil Is Dirty

Dirt on the evaporator coil could be the culprit of your cooling problem. Too much dirt accumulating on the evaporator coil interferes with warm air getting cold. The bad thing about dirt is that it creates a barrier that prevents warm air from making contact with the cold coil. A contractor can thoroughly clean the evaporator coil to fix the problem.

The Blower Fan Stalls

A stalling blower fan can cause a central air conditioning system to become inefficient. The blower fan is responsible for producing air, but it can stall if dirt or rust interferes with the rotation of the blades. Talk to an AC repair contractor so he or she can inspect and make the necessary repairs to your central air conditioning system.
