The "4-way valve" on my heat pump must be replaced. Because the dealership has chanaged hands and this is a warranty repair, I'm worried the new owner may try to take short cuts on what I'm told is "major surgery"
Can you guys help me prepare a short list of questions to ask the service manager in terms of what needs to be done to make sure my heat pump works as well as it did before the repair? For example, is it ok to reuse the FREON, or should it be replaced? Also, there's something called a "bi-directional filter drier" inside the outdoor cabinet. Should this be replaced or cleaned?
My unit has a scroll compressor with thermal expansion valve and runs on the old R22 FREON.
