. I will say though that I own an HVAC company and have been turning wrenches about as long as I have been walking . I would ask to see what parts they replaced first and foremost. I do not do a repair in a customers house without telling them and showing them whats wrong and what its going to take to fix it . I also never throw out old parts . I leave them by the furnace and show the homeowner they are there and leave it up to them if they want to put them in the round filing cabinet or not. I also always put the old parts in the new parts box and date the box for the date the new parts were put in. I would say if they cant produce parts and show you the new parts on your boat ( theres a problem) from what I can tell there is a problem as their fix didnt fix it. The BBB does wonders in finding a reputable company to deal with.
