I was called out to Joshua’s house for a cooling issue. Joshua has lived here for about 3 years so we performed a thorough evaluation. During the evaluation we discovered both systems are from early 2000s making them well past normal life expectancy, there is significant duct board which is dirty and has biological growth, the ac is low on the obsolete R22 refrigerant which is no longer made, and because it is so low there is likely a leak present that would need to be found and fixed.
