How Do Old Furnaces Differ From New Ones?

Are you thinking of upgrading your outdated heating system? Residential gas and oil furnaces have a lifespan of approximately 16 years. If your furnace is showing tell-tale signs of aging, such as poor fuel efficiency, frequent need for repairs, or uneven heat distribution, then it may be time to start shopping for a replacement.


The main difference between an old and new furnaces is efficiency. Modern furnaces waste less fuel when heating your home. They’re also engineered to better direct heat into your house rather than out the chimney.

Fewer Repair Costs

While installing a new furnace can be costly, it eliminates the need to invest in costly and unexpected repairs. Why sink money into an outdated heating system when you could reduce your energy bills with a new one?


When you install a new heating system, you may also opt to set up individual heating zones. This enables you to remedy uneven heat distribution or tailor settings to please individual household members.

Expert Eyes

When you hire a professional, such as Glenn Baker’s Heating & Air Conditioning, Inc. in Baton Rouge, to install a new heating system in your home, the technicians will examine every inch of your ductwork to ensure that it’s working as efficiently as possible.

Evaluating the Numbers

A professional heating contractor can help you compare your current furnace to a wide range of new ones. He or she can also calculate your furnace’s annual fuel utilization efficiency to determine your potential cost savings and reduced environmental impact.


Older furnaces are more likely to have faulty electrical components as well as excess carbon monoxide output. A seasoned HVAC professional can examine your existing heating system to determine whether or not it poses a potential threat. Often, the cost of replacing worn or damaged parts outweighs the cost of a replacement.

Multi-Stage Heating

Older systems run at one speed. Meanwhile, many new systems offer multiple heating stages. This enables a heating system to reduce its overall effort during times of lower output. This puts less stress on the overall system and enables it to run more efficiently.
