Do you have questions about your furnace?


Energy efficient Rheem furnaces

At GreenSavers, we only install the most energy efficient furnaces from Rheem. Most of our clients go with the Rheem Prestige Series 96% efficient gas furnace. We find that Rheem furnaces deliver high performance at a fair price, and relative to other manufacturers of high-efficiency furnaces, Rheem uses more robust components that last longer, saving you time and money. 


The energy efficiency of a furnace is measured by the "annual fuel utilization efficiency" (AFUE). AFUE tells you how efficiently a furnace converts the energy in its fuel to heat over the course of a typical year. The Rheem 96% efficient gas furnace has an AFUE of 96%. This means that 96% of the energy in the gas fuel becomes heat for the home; the other 4% escapes through the chimney and elsewhere. Another way to think about it - 96 cents on every $1.00 in heating energy expense actually warms your home.

Check out the brochure for an introduction to the Rheem Prestige Series 96% efficient furnace; details on one of the best warranties in the industry; or the spec sheet for an in-depth look at how the furnace operates. 


Performance and comfort: The two-stage heating design operates primarily on low-speed, only temporarily switching to high during the coldest weather conditions in Portland and Bend. That means you get maximum energy efficiency from your furnace while minimizing temperature variations in your home.

Quiet operation: The patented heat exchanger design provides improved airflow, which reduces operating sound by 20%. The variable-speed ECM motor also contributes to a quiet, more energy efficient operation. It’s engineered to provide better humidity control while using less power.

Reliability: Every Rheem Prestige Series furnace comes standard with the PlusOne Ignition System. Exclusive to Rheem for heating and cooling equipment, the direct spark ignition (DSI) system is arguably the most reliable ignition system available for furnaces in Portland and Bend.

Protect your home: The industry’s first blocked-drain sensor will shut off your furnace when a drain is blocked, preventing water spillage and potential water damage to your home. This and one of the best warranties in the industry translate to fewer repair bills for your heating system.


Proper furnace sizing makes all the difference


If you install a furnace that is too large for your home, you will experience a condition called short-cycling when furnace constantly cycles on and off, over-heating your home then cooling down below the set temperature. On the other hand, a furnace that is too small for your home will not produce enough heat to keep you comfortable on the coldest days.

To make sure your furnace is the right size, it's critical to know how your home uses and loses heat. This involves a detailed heat load calculation. Citeria to consider include: (1) the age and construction of your home; (2) insulation and airflow in the attic, walls, and crawlspace or basement; as well as (3) the integrity of your window and door seals. By installing a furnace that fits your heating needs, you'll save money on your energy bills, improve the overall comfort of your home, and extend the life of your heating system.

over-sized RESIDENTIAL furnace short cycling


A furnace that frequently cycles on and off will require more maintenance and fail sooner than a furnace that is properly sized for your home. The reason has to do with increased wear and tear on the heat exchanger.  By analogy, think of a car with only city miles and no highway miles. City miles involve a lot of starting and stopping, which wears on the engine. The over-sized furnace constantly starts and stops, accumulating wear and tear on its "engine," the heat exchanger. The result is that the over-sized furnace works harder and fails sooner.
