Ruud Gas Furnace

ruud gas furnace

Note: This article is only talking about gas/propane furnace. If you are looking for oil furnace, you can read our Ruud Oil Furnace Buying Guide.

Before you dive into the specific brand review, we highly recommend you to read our elaborate Gas Furnace Buying Guide in advance. There are several crucial steps you need to take before you even start to think about the brand.

Ruud gas furnaces are a common brand in America with several high-quality gas furnaces. The Ruud gas furnaces are nearly the same as Rheem in features and color. This is because Rheem is the parent company of Ruud. The major differences in these gas furnaces are the model’s names. There are no major differences in design. These two companies produce high-quality gas furnaces. However, their websites are very slow and difficult to navigate.
Ruud does offer high-end gas furnaces making it a great pick in the search of a gas furnace. The Ruud and Rheem parts are interchangeable.

Unique Features in the Ruud Gas Furnaces

  • Plus one water management system that allows the unit to detect any drains problems and shut the unit. The patented drain sensor helps protect the unit from any damage in case of drainage blockage.
  • The Econet feature allows the Ruud gas furnaces to communicate with various parts for efficient operation.
  • Two-stage gas furnaces that allow for two firing rates. This feature is available in a few selected models. The two-stage are used for very cold days and mild cold days.
  • The heat exchanger that is the most crucial part of the gas furnace is made of stainless steel aluminum. This feature makes the unit reliable and durable. Most Ruud units have inshot burners that allow for direct ignition.
  • Ruud gas furnaces have diagnostic abilities that allow the furnaces to self-diagnose and detect problems. This allows for troubleshooting of the gas furnaces and solving the problem.

Model Analysis

The Ruud Company produces three levels of gas furnaces that fit all the classes of consumers. The Achiever Series is the economy model with the efficiency ranging from 80% to 95%. The next model is the ACHIEVER PLUS SERIES furnaces that have the efficiency of up to 97%. The high-efficiency models are called the ULTRA SERIES that have over 97% AFUE ratings.Model U97V (from Ultra Series) is the high-end of all the product line with all the bells and whistles. We advise homeowners not forget to buy extended labor warranty when considering high-end models. In most cases, the labor fee for high-end series will skyrocket.

The Difference Between One-Stage and Two-Stage Furnace

If you’ve been shopping around for a new furnace, chances are you’ve encountered both one-stage and two-stage furnaces. As you can probably tell, not all furnaces are created equal, with some two-stage systems offering a superior performance that others simply can’t match. If you’re wondering how exactly they differ from your average one-stage system and whether or not they’re worth the cost, you’re not alone. The answer typically depends on a number of factors, however. There are many benefits to the use of a two-stage furnace and taking your needs, regional temperature and budget into consideration can help you determine if it’s the right choice for you.


What Is a Two-Stage Furnace?

To understand what makes a two-stage furnace unique, it’s important to know how a one-stage furnace works. In this case, the “one” actually refers to the valve that controls the burner section inside the furnace. Apart from being “closed”, the valve only has one position, which is “open”, and this allows fuel, typically natural gas or propane, to travel to the pilot light to ignite. The heat created in the burner section then heats up the heat exchanger where the air in your home is heated. In the “closed” position, no fuel is provided and thus the heat is off.
In a two-stage furnace, there are actually two positions apart from “closed” that allow the furnace to heat your home in different ways, on high or low heat. Like a one-stage furnace, there is a “full-open position”, but what makes a two-stage unit unique is the second, “partially-open” position.
Using a different programming system than a typical one-stage furnace, a two-stage furnace system can better determine how your home needs to be heated: using full heat, much like a standard one-stage furnace, or the reduced heating power offered by the second, partially-open position on mild-temperature days. This partial position only provides 60% to 65% of the power that the full-open position does, based on how often your thermostat turns the furnace on and off and offers advantages to the fixed, open position of a one-stage furnace.

Advantages of Two-Stage Furnaces Over One-Stage

Like most machines or products that offer more than one setting, two-stage furnaces have many advantages that one-stage systems can’t meet. Depending on your personal heating needs, these benefits can help tip the scales when deciding on the system that is right for you.

  • More Energy Efficient
    Because a two-stage furnace spends most of its time running in the partially-open position, it ultimately uses less fuel than a one-stage system constantly running at full capacity that only shuts off when the desired temperature has been met.
  • Better Air Filtration
    As a two-stage furnace runs more continuously in the partially-open position, this allows more air to circulate and pass through the filter, increasing chances of pollutants and allergens being trapped. This creates cleaner air for you to breathe while indoors.
  • Quieter Operation
    Especially if your furnace is located near a living room or bedroom, you’ll notice that a two-stage system is much quieter than a one-stage furnace. This is the result of the furnace not needing to “kick” on and off so frequently or at 100% power.
  • Balanced Heating
    Two-stage furnaces allow for more consistent heating without the drastic temperature changes that can be experienced with a one-stage furnace. Instead of firing at full capacity each time it runs, a two-stage furnace can keep temperatures fluctuations within only a couple degrees of the thermostat.

Is a Two-Stage Furnace Worth the Money?

Though typically priced anywhere from $500 to $1000 higher than one-stage furnaces, two-stage furnaces can ultimately save you money in the long run due to their energy efficiency. It’s hard to put a price on comfort or justify the initial price tag, but if the benefits outweigh the negatives, a two-stage furnace is definitely worth investing in. Especially when considering your regional climate, a two-stage furnace may be the better choice to cut down on energy bills and eventually offset the higher price.
It’s clear that a two-stage furnace goes above and beyond the comfort and personalization offered by a one-stage unit. Depending on your budget and climate, a two-stage system can improve the quality of your indoor air and even save you money in ways that a one-stage furnace simply cannot. Of course, that comes at an expense, but if you’re dealing with a trusted professional who can help you consider your heating needs, it’s a worthy investment and one that can transform your everyday life in ways you may not even imagine.

ECM Condenser Fan Motors vs. PSC Motors

Electric motors are an important part of HVAC systems. From powering blowers and water pumps to compressing refrigerant, electric motors perform some of the most basic functions that allow HVAC systems to do their job. Without them, we wouldn’t have access to heating and cooling as we know it.

Though they���re all designed to power a wide range of components, they’re not all created equal. In some cases, one type of motor will be favorable over another and by determining what function needs to be performed, we can determine which motor is most suitable for the task. ECM and PSC motors are two comparable motors, but they work in very different ways. These differences are an important part of their designs and they each have their intended purpose.

What Is a PSC Motor?

A PSC (permanent split capacitor) motor is designed with only two functions in mind: it turns on and it turns off. Because of its limitations and primitive design, the speed of a PSC motor cannot be controlled or altered, and when powered on, it runs at full capacity only. This constant speed means that, while it performs powerfully, it doesn’t do so efficiently and energy is wasted in the process.

What Is an ECM?

An ECM (electronically commutated motor) is a motor designed to perform similar tasks to a PSC motor but introduces variable speed. An ECM can be modulated and controlled to manipulate its behavior to meet the condenser’s call for airflow. Unlike a PSC which only has two stages, an ECM has many different speed settings that allow it to increase and decrease gradually rather than starting abruptly at full capacity. Its design makes it a more efficient and effective motor that has the ability to save a great deal of energy.


Any time that a fan or motor offers speed modulation, it will likely be the most efficient option. In the case of PSC motors and ECMs, this rings just a true and an ECM can offer the diversity that a PSC motor simply cannot.

Because of its variable speed settings, the energy required to power an ECM can be lowered or raised according to demand and will never perform at a higher speed than necessary. When the condenser fan doesn’t need to be running at full speed, the ECM can adjust its speed and save energy. A PSC motor, on the other hand, will always run at full speed, even when it’s not necessary. The lack of modulation, in this case, means that extra energy is being wasted to do the same job that a fan running at a fraction of its speed could do. It also means that a PSC motor is much louder compared to an ECM.


Like its name suggests, an electronically commutated motor is hooked up to an electronic control module. The module is programmed at the factory to perform a specific function, though it can be particularly sensitive to power issues and grounding issues. Before working with the control module, it’s important to disconnect any power running to it or the motor. Aside from the module, the motor itself requires a low level of maintenance. The use of ball bearings in an ECM means that it can run effectively for a long time without requiring lubrication. The gradual start and stop also has a positive influence on its lifetime and the reduced impact is easy on parts. In this same way, a PSC motor may require increased maintenance due to its sudden start and stop motion.

A PSC motor has been a standard in the HVAC industry for years, however, and they continue to be used today. Not only are they simple and inexpensive, but they’ve proven to be an extremely reliable component. The average lifespan of a PSC motor is around 40,000 hours, though an ECM surpasses it at 90,000 hours. Ultimately, an electronically commutated motor’s design bests that of the permanent split capacitor motor in almost every way.


Overall, the use of an electronically commutated motor can decrease energy usage by as much as 75% compared to a PSC motor. Not only will an ECM save on energy, but it will also provide more even and effective performance that will meet the demands of your condenser, however high or low that may be without wasting addition energy.

variable speed blower. Both are practical without any bells and whistles. If you didn’t have enough budget or plan to move house in the future, R96P and R96P are good temporary options. We didn’t recommend any kind of 80% AFUE gas furnaces (like R802P and R801T) no matter what features it has. 20% heating loss is huge. Even you want to sell your house immediately, the buyer will take heating efficiency into consideration when bidding.

Contractor Reviews

There is no such a thing as the perfect gas furnace. Most of these gas furnaces have similar features. One has to look at the unique extra features that have been added, the brand and professional contractor to do a proper installation. Wherever you read online, there will be negative and positive reviews depending on the experience customers have had. If installed properly, the Ruud gas furnaces are excellent and can help keep your home comfortable. They have very excellent efficiency that can help homeowners save on energy.

Ruud has been in the heating and cooling industry for over 100 years something that makes them a great choice. The company has steadily risen over the years becoming the largest heating and cooling company in North America. They are known to hire some of the highly trained specialists in the industry. The Company has evolved over the years producing gas furnaces with unique designs with a state of the art technology.
