Outside condenser unit blowing cool air, inside blowing about

Customer Question

Outside condenser unit blowing cool air, inside blowing about 80 deg air. Tried replacing the dual capasitor with no luck, when I shut the outside condenser unit off I hear hissing like an air leak for 20-30sec. Compressor is warm to hot, both lines going into the house are same slightly cooler than outside temp

It sounds like you have a leak in the system. That would be the hissing you are hearing. When pressure builds up from the compressor running you hear a hissing from a leak. You would need the leak fixed by a tech as the system is out of freon and would need to be recharged to get it cooling again.
