FurnaceCompare no bias towards or against any particular brand of heating and cooling equipment. Since 2002 our job has been to provide information, reviews and commentaries on equipment, not to tell you to buy one brand over another. Here’s what you need to know about Rheem furnaces.
What are the 10 Best Furnaces?
Rheem Furnace Series
Rheem presents their furnaces in three series, with several units in each series. The top end series, Prestige, offers five different units. The middle tier, Classic Plus, offers nine units, and the bottom tier, the Classic, offers six options. Prestige and Classic Plus units can reach 96% efficiency, while the highest efficiency Classic unit is 95% AFUE, so there is little difference in efficiency range, as each tier has a bottom efficiency model of 80% AFUE. The main difference is in technology, where most of the Prestige units are EcoNet ™ enabled. Other differences are in motors or design, though motor types are not consistent across series, so if you are keen to a certain type, look at each unit. All Classic Series come with permanent split capacitor motors (PSC). Classic Plus has PSC, electronic commutated motors (ECM) and Constant Torque ECM, while Prestige has ECM and variable speed motors.
- Most are EcoNet ™ enabled
- Also includes all listed below
- PlusOne ™ Diagnostics
- PlusOne ™ Ignition System
- Higher efficiency units come with PlusOne ™ Water Management System
- Most models, particularly the higher efficiency units, are similar to the Classic Plus. We had a difficult time distinguishing any true difference, except where specific features do not come with a specific unit in a series.
Where are Rheem Furnaces made?
Rheem is the same as RUUD, as RUUD is owned by Rheem. Rheem is owned by Paloma Group, which is headquartered in Nagoya, Japan. Rheem itself is headquartered in Atlanta, Georgia, with several plants within the United States. Their gas furnaces are manufactured in Fort Smith, Arkansas.
Rheem markets their EcoNet™, which is a smart thermostat. It has an app, which is compatible with Apple and Android, so the user can control their system from anywhere. Rheem also claims the user can place service calls with one click.
Another marketing item from Rheem is the Rheem-Exclusive PlusOne ignition system. This is Rheem’s direct ignition system. The company claims it to be one of the more reliable in the industry.
The industry-first PlusOne diagnostics marketed by Rheem is an LED display, which comes with a number of units. It is used for placing service calls.The PlusOne water management is a sensor in the furnace. This is a safety mechanism. The sensor will shut off the furnace if a drain is blocked.
What do Heating Contractors Say?
- Contractors note Rheem durability, one said they are “ built to last,” while another said a unit was 17-years-old and they, “never touched it”
- “Takes a back seat to nobody,” in regards to quality a contractor said.
- “…that Econet control is slick for not a lot of loot,” a contractor said.
- “Most reliable on the market,” a contractor said of Rheem.
- “Service friendly,” said a contractor.
- One contractor called the warranty, “worthless,” and there are other mentions of this issue.
- Another contracted noted, “all the hoops one has to jump through to deal with them.”
- Contractors mentioned that Rheem is not as quiet as American Standard/Trane, one contractor noted the difference in the “fan blade or compressor protection pressure switches.”
- Though there was some debate on this topic, one contractor claims Rheem technology lags specific to when EcoNet came out, “Rheem/Ruud units are 5 to 7 years behind the rest of the pack.” A different contractor countered with, ”Let’s see, Rheem was the first 100% Copeland scroll in the early 90s, the first 34″ furnace, the first tubular heat exchangers, the first direct spark in a modern inshot burner furnace and as beenthere [another contractor] said, way ahead of everyone on the modulating furnace.”
