The modern furnace, like the variable-speed furnace, is equipped with many technological innovations. They can provide unparalleled energy efficiency and high levels of indoor comfort. Therefore, consider a variable-speed furnace when your home requires a new heating system. Read on to learn more about variable-speed furnaces, including how they operate to enhance your home’s efficiency level.
What Is A Variable Speed Furnace?

Variable-speed furnaces operate at varying speeds, allowing for the optimization of indoor quality. This type of furnace can do this because it has a blower motor which is known as an electronically commutated motor (ECM). The term “variable speed” came from ECM, which is a direct current (DC) motor that utilizes a built-in inverter and magnet. The ECM’s configuration allows it to deliver improved energy efficiency compared to an alternating current (AC) motor. ECMs are also less costly to maintain and operate in general. Although a variable-speed furnace has a higher initial cost than a traditional (single-stage) furnace, it usually has a shorter payback time of around four to five years.
How Do Variable-Speed Furnaces Work?
A variable-speed furnace utilizes advanced HVAC technology to monitor and analyze data from your system. It will then adjust the speed using this data so that you will have optimal indoor comfort. This type of furnace will regulate how much air circulates throughout your home, compensating for any issues, like dirty filters and blocked vents, when needed. In addition, variable-speed furnaces usually take a while to reach full speed, unlike traditional ones. Variable-speed furnaces also run at full speed only when needed, consuming less power than their conventional counterparts that operate at full speed at all times.
The Differences between Single-Speed, 2-Stage, and Variable Speed Furnaces
A single-stage furnace always functions at full capacity. It doesn’t consider the airflow in your home when operating to reach the temperature setting of the thermostat. On the other hand, a two-stage furnace operates in two phases, namely, low and high. The low phase is when the furnace is in energy conservation mode. The furnace will try to use as little energy as possible when heating your home. When more heat is needed because of low outdoor temperatures, energy consumption is ramped up, moving to the second phase. This way, warm air circulates in the house evenly. A two-stage furnace works at 25% capacity on average most of the time. Therefore, it runs quieter and emits less carbon dioxide than a single-stage furnace.
Variable-speed furnaces provide higher efficiency and energy savings. It monitors and regulates the airflow in your home automatically, thanks to its computerized blower motor (ECM). This computerized blower motor allows a variable-speed furnace to provide your home with unmatched indoor comfort levels, energy efficiency, and more consistent heating output.
Variable-Speed Furnaces Can Improve Home Efficiency
A variable-speed heating system circulates even heat and humidity throughout your home, allowing you to enjoy improved indoor comfort. It can do so because it can control the airflow precisely. This heating system also uses up two-thirds less electricity and offers better performance than a single-speed furnace. It also operates quietly because it runs at a low capacity most of the time. Its speed ramps up gradually, so air fluctuations are minimized.
Variable-speed furnaces are usually equipped with smart thermostats so that the blower motor’s speed is controlled automatically. The smart thermostat can also be used to add HVAC system zoning, letting you heat different rooms in your house without blocking vents or wasting energy, which can result in a malfunctioning HVAC system.
A variable-speed heating system also provides a more precise and better temperature control in your home. After all, a furnace that runs on longer cycles and varying speeds allows it to respond more efficiently when indoor temperature changes occur. As a result, the furnace delivers hot air throughout your home consistently. It also reduces the chances of warm air building up at the top of the rooms.
Other Benefits Of A Variable Speed Furnace
Two more benefits that variable-speed furnaces bring are:
- Clean indoor air – A variable-speed heating system will push air through your HVAC system as long as the blower motor runs. This way, the system’s air filters trap more contaminants, and you’ll have cleaner and healthier indoor air at home.
- Humidity control – Variable-speed furnaces provide better indoor humidity control than single-stage heating systems. This is because variable-speed heating systems are more efficient in removing humidity from the air. Therefore, they are the ideal choice to prevent problems that arise from having high indoor moisture levels, including mold and mildew growth and increased allergen concentrations.
A variable-speed furnace is equipped with a computer that monitors and analyzes the airflow in your home. This allows it to adjust the motor speed automatically, so you receive optimal indoor comfort. A variable-speed system is more efficient, environmentally friendly, and has better temperature control than conventional heating systems. Moreover, it is more durable and costs less to maintain and operate.
