I was called out to Tamala’s house for a cooling issue on both systems. Tamala has lived here since August so we performed a thorough evaluation. During the evaluation we discovered that the main system is from 1998 and the upstairs system has a furnace from 1998 with an ac from 2013 making all the systems past normal life expectancy and the cause for the systems not working was a broken fan blade on the main system and a shorted contactor on the upstairs. I replaced both failed parts and the systems began functioning but both look to be low on refrigerant which indicates there is a leak on the systems somewhere that needs to be found and repaired to ensure functionality. Due to the advanced age, lack of warranty, and efficiency loss replacement is a viable option to update the system to current standards.
