Is $3,500 to perform a nitrogen pressure test to find leaks and replace refrigerant a fair price?
Project Details
I have a 14-year-old Lennox 4-ton HVAC system. I'm getting a 411 code indicating low pressure on the outdoor unit, which I suspect is due to low refrigerant. A technician inspected my indoor unit and found rust on the coil, which appears to be leaking into the area of the motor and control boards.
