Checked all operations in the cooling mode and found the Capacitor failed. The other components are showing signs of age which is causing more stress on this capacitor. Today we signed up for the maintenance agreement to monitor the unit as well as perform cleanings in the future. Replaced capacitor and tested all operations of the air conditioner after getting the air conditioner to turn on I found that the system is very low on refrigerant and only cooling about 6°.I want to see 17 to 20. Customers looking into replacement due to cost of repairs and condition.
