Replaced filter. Checked all operations. Highly recommend joining home care. Drain, coil and blower is starting to get dirty. Risk of water damage. No caps on service valves. Risk of refrigerant leak through valve cores. No das for zone system, risk of ice collecting on evaporator coil. Risk of losing ac. When it’s in the 90’s it’s going to be hard to keep it 68 in the house. Could have someone come out to see how well house is sealed and insulated.
