Are Variable Speed Furnaces Worth It? Facts You Should Know!

Variable speed furnaces – are they worth it? Absolutely! Compared to traditional single-speed furnaces, variable-speed furnaces are the way to go. They provide better indoor comfort and air quality with their DC motors, which use less power and run smoother than AC motors. Plus, they lead to energy savings of up to 30% each year!

Not to mention, variable speed systems require less maintenance than traditional models. However, when they do need servicing, you’ll want to make sure you’re working with a knowledgeable contractor.

So, if you’re looking for an efficient furnace upgrade, switch to a variable-speed furnace today! The benefits they offer are well worth any extra upfront cost. Get ready to enjoy better comfort and energy savings for years to come!

What are variable speed furnaces?

Variable speed furnaces are an HVAC revolution! They offer high efficiency, exact temperature control, and improved indoor comfort. Unlike traditional models, these furnaces have a motor that allows them to run at different speeds. This adjusts the heat and airflow based on the heating needs of your home. So, you get warm air without the noisy blast of single-speed furnace operation. Low fan speeds circulate air all day, leading to better air quality and energy savings.

Variable-speed furnaces give industry-leading efficiency for heating and cooling. They maintain the exact amount of heat/cooling needed with minimal energy usage. This means lower costs and reduced CO2 emissions.

These DC motors consume 75% less power than standard motors. Their speed can range from 30-100%, making cooling/warming your home easier.

For the most benefit from your variable speed system, hire a good contractor to maintain it regularly. It may cost more upfront, but you’ll save money and get better indoor comfort in the long run.

Are variable-speed furnaces worth the cost?

Variable-speed furnaces have been around for a while, causing homeowners to wonder if the extra cost is worth it. I asked James Blankenship of Hart Home Comfort, Woods Heating, and Skylands Energy Service about this.

He said that these systems are efficient and offer energy savings. This is because they can operate at different speeds, using a variable speed motor compared to traditional single-speed motors.

Plus, they provide superior indoor comfort, with less noise than standard air handlers. They also reduce cold spots by controlling airflow consistently. Finally, they help improve indoor air quality with more precise control of the fan speed or blower motor.

The downside is that implementation costs can be high. James insists that the upfront investment pays off in the long run, through increased energy efficiency and lower utility bills.

Plus, several manufacturers claim that variable-speed furnaces reduce carbon dioxide emissions. This is increasingly important in today’s world.

All in all, finding the right variable speed furnace is like finding the one – you need to know your needs, preferences, and compatibility.

Choosing the right variable speed furnace

Check the blower motor. Variable-speed furnaces have a blower motor that adjusts airflow for heating and cooling needs. This is quieter and reduces wear and tear. So, you’ll have lower maintenance costs.

Look for energy efficiency. Variable-speed furnaces use less energy than standard models. They have a higher Annual Fuel Utilization Efficiency rating. So, you’ll save money with this extra cost.

Choose a good contractor. Find a reputable company with experienced technicians to size and install your furnace. Get answers about installation, maintenance, and savings.

Not all homes need a variable-speed furnace. But, if you live in an area like Los Angeles or New Jersey, where heat pumps are used, the variable speed system will help reduce power consumption.

Invest in quality HVAC equipment. Hart Home Comfort installed my client’s new furnace. It offers even heating throughout their home – no cold spots or noisy blasts of hot air. One year after installation, the family had no system problems – saving them time and money on repairs.

Upgrade to a variable-speed furnace. You’ll have the energy savings to afford a therapist for your dark sense of humor!


Investing in a variable-speed furnace is worth it if comfort and energy efficiency are a priority. Benefits include reduced bills, better temp control, quieter operation, and improved indoor air quality. Variable speed motors adjust airflow, avoiding full-speed blasts of air like traditional models.

Variable speed systems save on maintenance costs too. Homeowners don’t have to worry about replacing their blower motors frequently since they last longer. And two-stage or modulating tech distributes heat more evenly than single-speed furnaces.

When installing, find a good contractor for proper sizing. Insulation and sealed ductwork help the system run efficiently. The upfront cost may be more but long-term energy savings make it worth it.

Pro tip: Clean or replace filters for better air quality. Maintenance is key for any system. Professionals like Hart Home Comfort (New York), Skylands Energy Service (New Jersey), and Woods Heating (Virginia) offer tune-ups for safe operation and optimal performance.
