Rheem "Classic 90" Furnace

Comparable Furnaces: Classic 90 Furnace Manual (pdf)

There are several families of furnaces in Rheem's Classic 90 Series, including a two-stage 92+% AFUE and two versions of single-stage 90+% furnace. The design of the Rheem Classic 90 Furnace is CSA certified.

Rheem does not offer an oil furnace in the 90+% AFUE range, although they do offer several furnace models in the Classic 80 line which have an AFUE that exceeds 80%.

Review:
"zero customer service"
I have one point to make - if you buy a rheem you will get no, NO, customer service - ever! They will not take calls and will insist you contact an independant service person - thereby ensuring you pay for service calls. Worst company I have ever dealt with!

Word of Mouth

Comments on the HVAC-Talk message boards and heating contractor sites are generally mixed regarding the performance and repair of the Rheem furnace:

  • One author at the HVAC-Talk forums claims that the Rheem fan doesn't work consistently, due to weak controls, but when the furnace does work, it produces a good amount of heat.
  • Another person claimed that Rheem is inefficient and does not always perform properly. This forum participant, like the other poster, felt that when Rheems does work, the quality of performance is noticeable.
  • A third person insists that Rheems no longer provides replacement parts, making the correct parts hard to find without an effort. However, Rheem diagrams provide clear direction for installation, so when these schematics are followed, effective installation and motor performance are assured.
