So I contacted Heat Controller about their brand to inquire as to if their Century furnaces have the exact same internals as Rheem/Ruud products.
"Heat Controller owns the Century brand name.
Our products are not Rheem's but are manufactured at the same location."
"So Heat Controller's Century Furnaces have pretty much the exact same parts as Rheem Furnaces?
Is there any price difference?"
"Our product is sold through wholesalers and we do not control their selling prices to the public.
Concerning the components, we don't have any knowledge of what components Rheem uses. A local dealer should be able to provide pricing to you if you are interested."
Do any of you professionals have a concrete answer? I'm very curious about this.
