Common Problems of Air Conditioners

Air conditioners are complex mechanical systems that depend on a variety of conditions to work properly. They have certain amount of ‘charge’ also known as the refrigerant. They have a certain amount of air flow across the coils with the help of a pump. When any of these things does not work properly, the air conditioning system will have troubles.

Sometimes, the air conditioning may not be able to perform properly, when more heat is produced indoor either due to more occupancy or through appliances in the home.

The capacity of the system is lowered when the refrigerant charge on the air conditioning system leaks out. It may not provide enough cooling and system may not be effective on the high load.

If airflow across the condenser (outdoor coil) is lowered, its ability to dismiss the heat outdoors is also reduced and the again the capacity of the system may fall down. This may especially happen at higher temperatures outdoor.

In dry climates, the same problems may arise with regard to the evaporator (indoor coil). Where, higher airflow helps the system and the lower airflow damages the system.
