A refrigerant shortage in the system: A refrigerant shortage forces the system to work harder to generate cold air. Because air conditioning systems do not consume or burn refrigerant, a low level indicates a leak or inadequate filling during installation.

Grime and dirt on the condenser coil: Dust, dirt, and grime can accumulate and become caked onto your air conditioner’s condenser coil. When dirt accumulates on the condenser coil, it makes it more difficult for the refrigerant inside the coil to condense back into liquid form, rendering the system ineffective.

Blocked air conditioning drain tube: When warm air meets cold evaporator coils, condensation occurs naturally. The accumulated water is collected in a drip pan and drained away from the system. If that drain line becomes clogged, water can back up into the system, icing the evaporator coil and causing the entire system to fail.

Faulty sensors or electrical controls: The compressor and fan of an air conditioning system rely on the flow of electrical current to function. If a faulty electrical control interrupts the flow of power, the air conditioning system will no longer function properly. Sensors inside the thermostat are also used by the system to determine when to turn on and off. Because of a faulty thermostat sensor, the air conditioning system may run continuously or not at all.
