Complaint water leaking on the floor Slower blower speed, checked low side pressure, cleaned coil, vacuumed drain. Need to confirm whether drain is trapped under house. If homeowner removes a section of skirting for access I will verify drain is code at no charge, if trap needs to be added time and materials will be charged upon completion. Gaping hole where drain and line set run through house is most likely pulling hot air into return. Should be sealed with spray foam
