Anyone who has spent much time around vehicles working on them. You don't have to suck on the tail pipe like it was your last doobie, but if you can stand there and smell the smoke you will get a slight taste in your mouth.
I can tell you as an HVAC professional, refrigerant leaks will never fix themselves. So either they found it and fixed it since it was something that failed that they didn't want to admit or you got a technician who literally has no idea what he is doing. R1234yf costs close to $100 a lb. The pilot holds roughly 1.5 lbs. My question is how close to 3 years old is your pilot because I'd wager they are trying to get away with a $150 refrigerant recharge, hoping it gets you through the 3 year warranty, than fix whatever is actually leaking since it will be significantly more expensive.
Thanks, it seems like the air is not blowing as cold again.
I will check the TSB and ask them about the issue that doa165 brought up (especially because most dealers seem to take the easiest path usually!)
If you have white smoke as a result of a cooling system then you have a cooling system problem. The only way it will go away is to have the system throughly checked and the proper repairs made. They will not heal themselves.
Makes sense, its common all around the HVAC trade, guys either can't or don't want to find the leak and they will refill it and hope the leak is small enough for it to last for a while so they can blame something else later. It's likely the condenser, if its not related to the TSB then you might have taken a rock to it since its a micro channel aluminum coil they crack pretty easy.
