I was called out to Nellie’s house for a cooling issue. Nellie has rented here for 5 years so we performed a thorough evaluation. During the evaluation we discovered that the system is from 2005 making well past normal life expectancy, the system is low on the obsolete R22 refrigerant which is no longer made, the flood protection needs updating to protect the system & house, the wheel and ac need cleaned, the blower motor & condenser fan motor are both worn out, the return ductwork is undersized, the bypass for the zoning is oversized, the system is not designed to work well with zoning and adjustments to the type of system or zoning needs to be done for proper operation, the heat exchanger is rusting and may not be safe to use now or the near future, the whip to the ac is improper wire, the capacitor in the ac has failed, and the evaporator coil is badly rusted and leaking. Due to the obsolete refrigerant repairs aren’t currently possible and updating the system is the best option for
