The answer to 'evaporator coil not cooling' is that a malfunctioning evaporator coil is a common problem that can prevent your HVAC system from cooling your home effectively. Some common causes include a refrigerant leak, a blocked airflow, or a problem with the blower fan or compressor. Symptoms may include warm air coming from the vents, high humidity, and the system running constantly without cooling.
In many cases, the solution may be as simple as cleaning the coil or replacing the air filter. However, if the problem is due to a refrigerant leak or a more complex issue, it's best to call in a professional HVAC technician. They can properly diagnose the problem and make the necessary repairs to get your system cooling efficiently again.
