Hello again, most home owners buy retail from local vendors who sell branded equipment. What you have is not particularly second tier. It is generally what we call a 'builders model'.. something like buying a stripped down model of a Chevrolet.
Same engine, same frame and body work... but no chrome trim, no sun roof, no electric windows, or power ash trays, heated seats.... but as functional and durable as any other chevrolet when it comes to transportation. It is sold to builders that way in order not to drive the prices down on the branded units, it also builds.
York owns the company and sells those furnaces to many other manufacturers some of them listed in this recall notice for one of the modelsCLICK HERE
If you can give me the model number of the unit from the tag you mentioned, we can check it against this recall notice and also get more data on its efficiency and features.
The most important thing with these systems is the quality of the installation, namely adequately sized duct work, sealed against leaks... that suffers badly with many home builders, it is a problem especially on two story homes.
Tell me a bit about that.
... and let me know the model numbers, we can go from there.
