Overview of the Classic 90

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%.

"Unhappy with Warranty handling"
My furnace needed a $286 repair within 2 years. The connectors powering the gas valve were not connecting properly and needed to be crimped tighter after 2 years. However my big dissatisfaction is with their handling of the warranty. I was late getting it registered so the company cut the warranty from 10 years to 5 years. I have decided I will send no more money to the company that makes Rheem Furnaces as a result of this and I have started researching their replacement for the time when they will not cover a part under warranty. I also found the warranty itself unacceptable. It gives me the feeling they really do not want to have a warranty and their action sure seems to back this up. I told them of my plan to replace their furnace with a competing furnace. We will see if they back down on their threat.

"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!

Other Classic 90 Reviews

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.
