All You Need to Know About Furnaces with Variable Speeds

Today, furnaces are built with state-of-the-art technology to provide homes with a comfortable atmosphere while also delivering great energy efficiency. Furnaces that run at variable speeds accomplish this goal while limiting the amount of energy consumed and providing greater air quality and temperature control. It’s a win-win situation for anyone looking to install a heating system in their home. Let’s take a look at some key aspects of these furnaces.
How are variable speed furnaces different?

A variable speed furnace includes an electronically commutated motor (ECM) blower motor. This piece of tech allows the appliance to operate with increased energy efficiency. In contrast with furnaces that use AC motors, these variable-speed versions use DC motors with magnet rotors and inverters.

How does a variable-speed furnace work?

As the name suggests, a variable-speed furnace can run at multiple speeds in contrast to other furnaces that have one gear. Cooling and heating airflow are controlled throughout the home with these various speeds. Monitors within the furnace intake data from the HVAC in order to adjust the motor speeds when necessary.

Better Energy Efficiency

Variable speed furnaces “detect” the cooling and heating needs of a home and will deliver the right amount of air to meet these requirements. The monitors in the furnace take into account air circulation as well as dirty filters to adjust the speed of fans to achieve the ideal airflow.

Furnaces with variable speeds will only flow at full-blast when necessary. The design of these appliances makes them much more energy-efficient than traditional models due to their ability to produce adequate cooling and heating while operating at decreased speeds.

Older furnace models wait until the temperature of the home reaches a certain point before adjusting. A furnace with variable speeds can provide homeowners with a more consistent atmosphere throughout the day by keeping the airflow and temperatures more steady.

Improved Air Quality

Furnaces with variable speeds clearly improve your home’s energy efficiency, but they’ve also been proven to boost indoor air quality. When the heating’s fan is operating continuously, the blower motor is always pushing air throughout the home, even when it’s unnecessary.

These newer models have furnace motors that operate at efficient but low speeds in order to improve air circulation. An increase in air circulation directly correlates with improved air quality because the air is being sent through your furnace’s filter more often. All nasty particles and contaminants are being trapped and your family is breathing cleaner air.

Pricing of Variable Speed Furnaces

Typically, HVAC products with greater energy efficiency come with a larger price tag. However, the extra money you spend on a variable-speed furnace will be made up through the money you save on utilities. When it comes to installation costs, it all depends on the model selected, the rates of the installers, and more.

After using a variable-speed furnace for around 4 to 5 years, your investment will be paid back in savings. In other words, your furnace pays for its own price tag within a few years of constant use.
