Rheem/Ruud Oil Furnace Prices and Reviews 2021

Rheem and Ruud are sister brands with identical oil furnace models made in the same factory and given Rheem or Ruud badging. There are just three models, but each is made in a variety of versions, as shown in the table below. If you’re shopping for an oil furnace, you are likely replacing an older oil furnace and live where natural gas and propane is expensive or not available. Otherwise, see our Gas Furnace Buying Guide to compare oil and gas. You’ll see the advantages of a gas furnace over oil.

If you’re starting your research on oil furnaces, the Oil Furnace Buying Guide we produced includes general information about oil furnaces, their pros and cons, top brands and average costs for those brands.

Introduction to Rheem/Ruud Oil Furnaces

Rather than make one Energy Star furnace and one near the low end of the efficiency spectrum, as other brands do, Ruud and Rheem make three models with similar efficiency, 86.5% to 85.9% AFUE. Each comes in standard, high-boy (upright) and low-boy compact models to suit your installation needs.

Here’s an overview of the Ruud oil furnaces and Rheem oil furnaces to compare with the tables we’ve created in the other brand oil furnace reviews.

  • 1). A PSC motor is a permanent split capacitator motor that has been “standard” for decades. They cost less but use more energy than ECM motors, or electronically commutated motors.
  • 2). Since oil furnaces are single-stage heating appliances, almost any thermostat including those from other brands will support them. If you pair the furnace with a two-stage air conditioner, the thermostat must support two stages of cooling.
  • 3). Rheem groups these oil furnaces with its Classic Series; Ruud places them in the Achiever Series. Those are the second-best series from each brand.

Rheem and Ruud Oil Furnaces Features Analysis

ROCB models use a primary and secondary heat exchanger. They pass combustion gases over the heat exchangers three times to transfer a higher percentage of the heat created before it is exhausted via the chimney.

The 10-gauge primary heat exchanger and 14-gauge secondary heat exchanger are among the thickest and most durable made. This is important because cracked heat exchangers sometimes cause carbon monoxide leaks and they are so expensive to repair that it typically means furnace replacement instead.

Ruud and Rheem offer the widest range of burner options in the industry: Beckett AFG, Carlin EZ or Riello F3, F5, BF3 and BF5 burners. All perform similarly and are highly rated, so ask your HVAC installer about which burner will work best for the size and performance your furnace is capable of providing.

Oil furnace installation averages $1,400-$1,800 but can be as low as $1,000 or as high as $2,000. Installations in crawlspaces and attics are more difficult than installing a furnace in a basement or first-floor location. When the sheet metal plenum must be replaced or a new chimney vent installed, costs can be higher. In spite of the cost, oil furnace installation isn’t something you want to cut corners on because an improperly installed unit can be unsafe, run inefficiently and have early mechanical failure.

The installers are licensed, insured and pre-screened for experience, and the companies know they’re competing for the work.
