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Are you thinking of upgrading your outdated heating system?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 Why sink money into an outdated heating system when you could reduce your energy bills with a new one?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.

How to Check for Air Leaks in Your Home

Air leaks are extremely common in homes on areas that include windows and doors. Although air leaks are common, they can lead to increased energy usage and higher bills throughout the year. If you want to check for air leaks in your home to protect the interior setting, then there are a few important tips to follow.

Perform a Visual Inspection

You can discover air leaks that are present by performing a visual inspection where the different building materials meet. Inspect areas where outdoor water faucets are present, where siding and chimneys meet and all exterior corners. When inspecting the inside of the house, check switch plates, attic hatches, vents and fans, and electrical or gas service entrances.

Perform a Pressurized Test on the House

Those who have difficulty locating leaks can perform a pressurized test on the home to increase infiltration through leaks and cracks. You’ll need to shut all windows and doors while turning off combustion appliances. Light a candle or incense to determine where the smoke moves horizontally, which indicates where air leaks are present in different areas of the house. Using a damp hand to feel for air leaks will also make it easier to determine where the air is entering the home from the outside.

Use a Flashlight

At night, use a flashlight to shine light over areas where gaps may be present to determine where air leaks have formed as another person evaluates the exterior of the home. If he or she sees any light shining through, then it will allow you to determine where caulking is needed to seal the house. You can also shut a door or window on a dollar bill to determine if it slides out easily, which will reveal if gaps are present.
