Service Call After Hours Fee-16 yr old heil ac unit. Replaced failed capacitor to get system running. System is running on low suction pressure(85). Customer said he had water on floor by furnace. This would be from the coil freezing. Added some refrigerant to the system but it was not affecting the refrigerant pressure. System has a restriction in the line. We can try pulling a vacuum but there is no guarantee that would fix issue. Customer wants an estimate to replace system, office will be in touch to schedule an appointment.
