I arrived for a new system bid. I spoke with the homeowner and found that they want to replace the system and try to finance the new system. I inspected the indoor and outdoor system and found the evaporator coil to be incased in the plenum and not accessible. I bid a new system and just a evaporator coil and condenser only. I also bid to add refrigerant to the system but the homeowner did not want to keep spending refrigerant cost on this system every year. I left the system in the same condition as I found it.
