Question

Rheem Plus 90 Furnace


Just got a new Rheem Plus 90 - 3 Stage Gas Furnace installed.

The outdoor exhaust pipe noise is high. One can hear it a few houses down the road.

As a homeowner of this new heating system, what should I begin to observe on its operation? How would I know if the system is working in 3 stages?

Check the install manual to see if its installed correctly.

I have no idea, why anyone would buy a Mod furnace, and then cripple it by down grading it to a 3 stage furnace(if its connected and wired properly to a 2 stage stat), its only 2 stages if wired to a single stage stat.
Its a waste of money.

Should just have gotten the 2 stage which is higher efficiency, if you don't want to spend the money on the Mod control.

If your ear can't tell you, then you may very well be operating in one stage only.

What is the model #, square footage of your house, and location?

Amen, Been.

Please..As an installer I will go back and talk to my customers and see how they like the furnace. And ALOT have a lower bill.
Appearently you are not well educated in how this furnaces work.

Show where in the install manual, or any where in Rheems lit, that they say their 90% Mod, will use less gas then their 95% 2 stage.


As an installer.
Check your records. See what size and efficiency furnace you removed before you installed the Rheem MOD.

Comparing a 90% mod to an old barely 70% AFUE(if even that), doesn't tell you squat. An 80% single stage will save money in those swap outs.

Pull a 94% single stage, or a 95% 2 stage and see how it compares in energy savings.

What was the TESTED efficiency of the 90% AFUE Mods you put in.
And what firing rates did you test it in???

Or don't you test what you install???

While the Rheem Mod is the best controlled Mod furnace on the market, It is FAR from the most efficient furnace on the market.

And it doesn't become more efficient at lower firing rates.

If it did, the the York MOD 98% AFUE(with a lot more steps of modulation, 65, compared to Rheems 13), would become more then 100% efficient when it was in its lower firing rates.


A properly sized Rheem 95% 2 stage, will use less gas, then a properly sized Rheem Mod, in the same application.

So if not using the Mod controller, might as well get the higher efficiency 2 stage.
