Friend of employer calls and I go look at his summit pool heater (heat pump only).
Says it was letting a lot of water out. At first I thought just coil condensation but the gray pvc shell that hoards the heat exchanger has a nice semi circle cracked in the bottom.
He bought it himself, he said from Johnson controls Is it a york derivative? I quickly googled it and can only find their main website. I found no model or serial on the whole unit There is one on the heat exchanger I might reference. It's R22. Frustrating.
ETA it's about 4 years old according to customer.
