Trane dealer serviced my HVAC. He says the TXV valve is defective, brand is Sporlan. He said this is a well known issue from a certain period.
Anyway, he wants to replace the TXV but also the drier and put new R22 into the system. Are the drier and R22 necessary or is he trying to get more money out of this repair?
Is the Sporlan TXV defect really well-known. The system was installed in 2007.
The problem was AC could not cool the house enough in the afternoons, when it is 100 degrees outside. Morning and night seems OK.
