What Are the Benefits of a High-Efficiency Furnace?


If you bought a new smartphone, you’d expect it to include a camera.

If you were shopping for a new car, you wouldn’t be impressed if the salesman told you “This one comes with airbags.”

Some things are just standard these days.

The same thing applies when you’re searching for a new furnace. Higher efficiency units are the norm now. By law, they need to be at least 80 percent efficient, although higher-end furnaces are even more efficient.

But what are the benefits of installing a high efficiency furnace? Read on to find out.

If you have an older system – installed in the past 20-25 years – you might have a furnace with a 65 to 70 percent AFUE (annual fuel utilization efficiency) rating, which means you’re losing 30 to 35 percent of the heat your furnace produces.

In other words, one third of every dollar you spend on heating is being wasted. But a modern, high-efficiency furnace will typically have an AFUE rating of more than 90 percent, which means your system will soon pay for itself.

Modern technological advances in HVAC systems such as variable speeds and modulating gas valves have led to more even heating, better humidity control and consistent temperatures and air flows, all adding up to a much more comfortable home.

One standard feature of modern, high-efficiency furnaces are programmable thermostats, which can give you new levels of control over specific rooms. You’ll have the ability to keep some spaces warmer or cooler than others, while setting your system to use less energy when you aren’t at home.

4. Less noise

A high-efficiency furnace will typically be made from sound-absorbing material, meaning it will make significantly less noise while running than an older unit. You’ll feel the effects of your furnace while never having to hear it.

High-efficiency heating systems use a third less fuel than older models, which prevents waste and conserves resources. You’ll save money while helping the planet.

6. Longer operating life

Newer furnaces are designed to minimize on/off cycling, which means they won’t need as many repairs – assuming they get regular maintenance – and will last longer than older units.

If you ever decide to sell your home, potential buyers will want to know about your HVAC system. A newer furnace can increase the value of your house and help you sell quicker.

How do I know it’s time for a new furnace?

Signs it’s time to replace your furnace include:

  • The age of the system – furnaces will typically last between 15 and 20 years. You can find out how old your unit is by checking the installation date. It might be written on the back. If not, check the serial number/model number and visit the manufacturer’s website to find out when your furnace was installed.
  • Replacements vs. repairs – Ask yourself two questions: Has the furnace passed ¾ of its life expectancy? Will repairs cost more than one third of the cost of a new furnace?
  • If you have serious issues that may be causing 
  • a safety hazard – a cracked heat exchanger, for example – it’s time to replace your furnace.
