Completed with heat 2 on 2018 carrier heat pump upflow in closet, 3 ton main downstairs and 2.5 ton upstairs. Found upstairs freezing up from outside distribution tubes due to being very low on 410A refrigerant, didn a leak search and leak detector went off on evaporator coil, fan motor showing wear. Giving customer the option to do all preventative repairs, minimum repairs, condenser heat pump or complete unit upgrade. Customer asked for pricing for a new air handler or complete unit upgrade, customer needs to talk to wife before making any decision. I'll be calling the owner to try to get customer a better deal.
