What Is A Variable Speed Furnace?

As you can easily understand from its name, a variable-speed furnace can operate at different speeds to enhance indoor comfort. The presence of an electronically commutated motor (ECM) is a fundamental feature that allows the furnace to accomplish this. In other words, the term variable-speed refers to the ECM mentioned above, which is a direct current that utilizes a built-in inverter and magnet rotor. This kind of configuration is designed to allow an ACM to deliver better energy efficiency when compared to an alternating current motor.

Additionally, ECMs are cheaper to maintain and operate. Hence, even though the upfront cost for the variable speed furnace may be higher than a traditional one, the long-term benefits of the multi-speed furnace are satisfying. It also has a short payback period of about four to five years.

How Do Variable Speed Furnaces Work?

First, the variable speed furnace utilizes advanced HVAC technology to monitor and analyze the data from the system HVAC system. It automatically implements the necessary speed adjustment to enhance your indoor comfort. Additionally, it regulates the air circulating in your home, thereby compensating for factors such as dirty filters and blocked vents by adjusting the fan’s speed as necessary. Besides, unlike the traditional furnaces, the variable speed furnace can take a while to attain full speed. The benefit of this is that it allows them to run smoother and more silently than the traditional furnaces. Moreover, since they run at a top speed when necessary, they consume less energy when compared to traditional furnaces. Therefore, if you want to invest in an HVAC system that will help you reduce money, this is the right option.

The Differences Between Variable-Speed, Single-Speed & 2-Stage Furnaces

Understanding the difference between variable-speed, single-speed, and 2-stage furnaces can prove significant when deciding on the furnace you want for your home. There are several aspects that one needs to look at when distinguishing between the trio. For instance, a single-stage furnace is known for operating at full capacity all the time. In other words, it does not consider the airflow inside the home when attaining the thermostat’s temperature setting. On the other hand, a two-stage furnace employs two phases: the high and the low. The low phase is an energy conservation mode, while the high energy level mode is efficient when the temperatures outside your home are low. A two-stage furnace operates a 25% capacity on average most of the time. Consequently, it runs quieter than a single-stage furnace. Further, it produces less carbon dioxide.

Variable-speed furnaces are equipped with ECM that enables them to monitor and automatically regulate the flow of air in your home. Due to high automation levels associated with the variable speed-furnace, it offers better energy savings and efficiency compared to other types. High indoor comfort levels, consistent heating output, and unmatched energy efficiency are imminent with variable-speed furnaces.

Variable-Speed Furnaces Can Improve Home Efficiency

The variable-speed furnace control airflow precisely distributes humidity and heat evenly throughout the room, improving indoor comfort levels. Further, a variable-speed heating system utilizes approximately two-thirds less electricity when compared to a single-speed furnace and performs even better.

Also, since a variable-speed furnace operates at a low capacity, it ensures quieter operations. Interestingly, a variable-speed furnace ramps up speed gradually, allowing it to minimize air fluctuations.

Variable-speed furnaces come with smart thermostats, which are responsible for automatically controlling the blower motor’s speed. Additionally, you can use the smart thermostat to add zoning to your HVAC and hence allow it to heat your home without blocking vents or wasting energy. The blockage of vents can result in your HVAC system malfunction.

Another way a variable-speed heating system can improve energy efficiency is by offering more precise and better temperature control in your home. Varying speeds and longer running cycles mean that the furnace will always respond efficiently to indoor temperature variations and hence deliver a consistent supply of warm air throughout your house. This reduces the possibility of the warm air collecting at the top of the house.

Other Significant Benefits Of A Variable Speed Furnace

The truth is that the variable-speed furnace comes with multiple benefits, and some of them include;

  • Clear Indoor Air: homeowners install HVAC systems in their homes because they want clean and pure air. When the blower motor is running, the system keeps pushing air through the HVAC system and allowing the air filters to trap contaminants, leading to clean and healthy indoor air.
  • Humidity Control: When comparing variable-speed furnaces to single-heating systems, the latter offers better indoor humidity control. In other words, they are more efficient in eradicating humidity from the indoor air. Consequently, the variable-speed furnaces are ideal in situations where there is the need to prevent moisture problems. For example, it helps prevent mold growth and increased allergen concentration.



A variable-speed furnace utilizes a computer to analyze airflow in your home. It automatically adjusts to optimize your home’s comfort levels. The single-speed furnace lacks this feature. Further, the variable speed is more environmentally friendly, more energy-efficient, and offers excellent temperature control. Also, it is affordable, durable, and cheaper to run and maintain.
