Rheem 80% to American Standard 95% Variable 2 Stage (again)

I can not tell you how many RHEEMs I have replace in my life, perhaps over 100? Maybe more I do not know, but I can tell you I really enjoy doing it! And I can tell you in most cases I usually find something seriously wrong with the installation. Now stating that RHEEM furnaces caused heating contractors to do poor installations would be absolutely wrong, but stating that RHEEM furnaces in their day where more economical to purchase and that may have attracted more of the spec market heating contractors might be more on target.

Here we are replacing a RHEEM 80% with an American Standard 95% Variable 2 Stage, As you can see we already pulled the unit off its base can exposing something very wrong in the base can.

On a side note, this furnace was actually screwed to the wall for support, this is a big no no in my book. Screwing the furnace to the wall will allow vibration noises to directly transfer into the home.

Now looking into the base can you can see the trunk line that not only was not sealed, the tabs where not even secured (bent over) to the base can. This drastically cuts off air flow and cause excessive leaking into the garage and or crawl space.

The older RHEEM had many repairs done through out the years, all in my opinion can be directly related to the poor installation by the previous heating contractor.

Here we have the new American Standard 95% Variable 2 Stage installed. We also replaced the older base can with a new sound lined base can making sure to seal it to the trunk.

Great detail with this post. We come across so many installation issues like you talk about. Frankly, we’re seeing more and more with the quick installs done during the housing boom in the early 2000’s. They lasted awhile, but are all dying out now.

You’ve given us some great ideas for our blog. http://www.trusthomesense.com/blog
