I had JA Sauer do an emergency repair on my gas furnace last year (called them because they had installed the furnace way back in 93 according to the servicing sticker, long before I even owned the house... I would have been 11 that year lol)... they looked at it, identified the problem, but said with the age of the furnace they may not be able to find the part. They found it though... and did the repair rather than just trying to replace it. So I was happy and felt it showed a degree of honesty. I don't know much about metro to compare., but JA Sauer is reputable in my opinion.
