After the winter season ends, the temperatures start to climb in New Orleans, Louisiana. After a period of non-use, your home’s air conditioning system may start blowing warm air when you switch the system to the cool setting. Take a closer look at what may be causing the air to come through your vents warm to determine next steps.
When the air conditioning system has a restriction in its airflow, you may notice that the air coming through the vents feels weak and warm. Restricted airflow can also cause the unit’s compressor, the component housed in the outdoor unit that moves refrigerant, to freeze up. Since the compressor is vital to the overall operation of your AC, it’s best to leave any inspection or repairs to an HVAC technician.
However, you can check the air filter to determine whether it’s the cause of the airflow restriction. A dirty, clogged air filter won’t allow air to move through it properly. Dirty coils can also be to blame, which a technician can clean as part of a regular cooling system tuneup.
Loss of Power
A central air conditioner includes the indoor and outdoor units. Within the indoor unit is a fan that moves air throughout the space, but it only works if it has power. The outdoor unit also requires power since it houses the compressor, which is the component that moves refrigerant to move heat from the indoor air. If you have a blown fuse on your electrical panel or the power is out, your AC won’t be able to produce and move cooled air.
Low Refrigerant Levels
Another problem that can cause air to feel warm is a low level of refrigerant. This usually occurs as the result of a leak in your refrigerant reservoir, as this material can be re-used and doesn’t run out through normal use. An HVAC technician can check the tank and come up with a plan for repair.
