Came out for a no cool on a 2018 R410a system. I found that the system was completely frozen over from the outside unit to the indoor unit. I thawed out the system and checked the furnace as well as the outdoor unit. The furnace was fine all electrical components and motor tested well. I suggested an indoor air quality product for the organic growth that was in the system due to water and build up. The outdoor unit was completely frozen over due to a leaky evaporator coil and a failed compressor. The contactor and capacitor both were both out of range. I gave repair options to the customer as well as offered to have an install supervisor out to quote new equipment. The customer declined the IS and choose the Band-Aid option. I’m waiting to hear back from the part supplier to set up the appointment for the repairs.
