Upon arrival the homeowner stated the AC froze up and refrigerant lines were iced up. the blower was operational and filter was clean. I did advise the homeowner that filter was restrictive type. The system is estimated 3 pounds low on 410a refrigerant. I spoke to home warranty about issue, refrigerant or leak search was not covered. I quoted refrigerant top off per homeowner request. The homeowner authorized top off and timeline. The unit took 3 pounds of 410a. I quoted all possible repairs to homeowner. Everything was operational when leaving.
