This option is the least expensive option that would safely address what we were called out for. Customer had home warranty put in upstairs unit and outdoor unit three years ago, every since then he’s had a major leak somewhere inside of the outdoor unit. Refrigerant has been needed to charge the system twice (18’ & 19’) suction line psi was at 0, blower wheel was 100% impacted air filter was 0% impacted. Husband is the only one working and wants to complete the leak search on June 10th and get the done.
