"Worst AC unit"

1.0 rating
Very Unsatisfied

Read reviews! Do your homework! If you do not care about your money and stress is your thing. Then, by all means…BUY A rheem RSMA. You'll get all those things and more. There products don't work correctly. I'm perplexed how they even made it to the level they are as a company.

Other RSMA Reviews

Having been discontinued several years ago, this model has few mentions on discussion boards across the web. Reviews for Rheem cooling units, in general, are mixed. While review sites such as webhvac.com recommend Rheem products for efficiency, durability and having a high quality service record, homeowners aren’t as pleased.

Many posters on consumer forums air grievances that their Rheem unit has had multiple repairs over the years for different components, often including the circuit board and coils. Similarly, hvac-for-beginners.com rates high tier Rheem products lowly for using standard compressor technology, and for offering a warranty that’s not as competitive as other brands.
