Am I being scammed? HVAC
I have a 3 ton unit for my home that is original from 2009. Few days ago I tried to turn it on for the first time this year after winter but the outside unit wouldn't turn on. The furnace blower runs but the outside fan and compressor does not.
I called this HVAC guy from Kijiji. He charged me 50 bucks for initial diagnosis. After he spent sometime at the outside unit and the furnace panel, he said that the high voltage current was flowing to the outside unit which he was about to run with bypass. But the low voltage current was not passing through so the ac unit needs a new PCB and another component I don't know the name off. The issue then was that the keeprite model on the side plate has worn off with age and he took two days to try to find the right parts. Today he called me and suggested that he thinks he has the right part but it's not guaranteed to work. The parts alone will cost 200 but the supplier will not return them in case they are not compatible.
Does this sound reasonable or am I being scammed?
