Is your AC unit failing to blow cold air?
AC problems such as this typically occur during the worst possible times, such as a scorching-hot summer day. If left unchecked, your AC unit will continue to recirculate the warm and humid air throughout your home, allowing indoor temperatures to climb.
If your AC unit isn’t blowing cold air, one or more of the following problems could be to blame.
Dirty Coils
AC units have coils, including the evaporator and condenser coil, that are used to transport heat and cool the air.
If either of these coils becomes clogged with debris, it will lower your AC unit’s cooling power. You can find the evaporator coil inside your home. The condenser coil, on the other hand, is typically located outside.
Inspect both coils for debris buildup and, if necessary, clean them.
Dirty Air Filter
In addition to dirty coils, a dirty air filter may prevent your AC unit from blowing cold air.
As air enters your home’s heating, ventilation and cooling (HVAC) system through the return vents, it must pass through a filter that catches and removes particulate matter from the air.
Over time, air filters may accumulate so much dirt, hair, dust and other debris that it restricts airflow.
As the air entering your HVAC system slows down, you may experience room-temperature air with the AC unit turned on.
To prevent problems such as this, remember to change your air filter once every couple of months. If you live with animals you may want to change it every month.
Refrigerant Leak
A refrigerant leak can result in room-temperature air with your AC unit.
Refrigerant is stored in both the condenser and evaporator coils. Both coils are designed to be closed, meaning refrigerant levels should remain consistent. Unfortunately, there are instances in which refrigerant can escape.
If a coil is punctured, the refrigerant will leak out until the levels are no longer sufficient for proper air conditioning.
Tripped Circuit Breaker
There’s also the possibility that a tripped circuit breaker is preventing your AC unit from blowing cold air.
Depending on how your HVAC system was wired, the evaporator coil and condenser coil may operate on separate breakers. The evaporator coil, for example, might be wired to your home’s outdoor breaker, whereas the condenser coil might be wired to your home’s indoor breaker.
If the outdoor breaker trips, it will disable the condenser coil, resulting in room-temperate air.
