Nobody wants to replace their furnace, and most people would do whatever they can to get the most out of it. While furnaces last a long time, they eventually go bad just like any part of an HVAC system. So, how long does a furnace last in NJ?

A furnace lasts for 15 to 30 years in NJ depending on how well you take care of it. However, problems such as cracks and corrosion can cause a furnace to fail sooner. Frequent repairs, short cycling, excessive corrosion, and uneven heating are all signs it’s time to replace your furnace.

Schedule yearly maintenance visits to assess how much longer your furnace will last. By addressing problems early, you can avoid sudden furnace failures. Let’s explore how long a furnace lasts in New Jersey and identify key signs to watch for.

What is the Life Expectancy of a Furnace?

A furnace can last for 15 to 30 years. You can expect your furnace to last that long in NJ if you keep up with regular maintenance. Schedule annual maintenance checks to clean and calibrate your furnace, addressing small problems before they grow into costly repairs. Preventative maintenance is key to furnace longevity.

Change your furnace filter every 90 days and avoid constantly adjusting your thermostat to help extend the life of your system.

How Do I Know It’s Time to Replace My Furnace?

1. Age

Age is the leading cause of furnace failure. Most furnaces begin to show signs of wear around the 15-year mark. With proper care, your furnace may still perform well for another decade or more, but as it ages, it will work harder, increasing your energy bills and potentially damaging key components.

2. Loud Performance

Unusual sounds such as humming, popping, grinding, or shrieking can signal trouble. While not every noise means you need to replace your furnace, multiple sounds paired with failing parts may suggest it’s time for a new system. Fixing these issues is worthwhile if your furnace is younger, but older furnaces may need a full replacement.

3. Uneven Heating

A furnace should heat your home evenly. If you experience uneven heating, this could indicate furnace problems, especially in older units. A faulty thermostat or blocked vents could also be the cause. An inspection can determine the root of the problem.

4. Regular Repairs

Frequent repairs are common with older furnaces. While yearly maintenance is essential, your furnace shouldn’t need constant fixes. If repairs are becoming expensive and frequent, it may be more cost-effective to replace the unit.

5. Constant Cycling

Short cycling occurs when your furnace turns on and off repeatedly without completing a full heating cycle. This strains your system and increases energy costs. While short cycling can result from issues like a dirty filter or faulty thermostat, it may also point to serious problems like flue damage or air leaks. Regular short cycling in older furnaces could signal the need for replacement.

6. Cracked Heat Exchanger

The heat exchanger is crucial for keeping harmful gases like carbon monoxide out of your home. A cracked heat exchanger poses a serious risk. Replacing this part is possible, but it’s often recommended to replace the entire furnace, especially if it’s aging and has other issues.

7. Excessive Soot

Soot buildup indicates combustion issues and can signal problems during furnace installation or operation. Soot around ducts or near the pilot light and burners suggests leaks and needs to be addressed immediately, as carbon monoxide may be present.

8. Corrosion

Corrosion can affect several furnace parts, including the heat exchanger, fuel lines, and burners. While you can replace corroded components, widespread corrosion often requires a full furnace replacement.

How Much Does It Cost to Replace a Furnace in NJ?

It typically costs between $2,800 and $7,000 to replace a furnace in New Jersey. The cost varies depending on factors such as the furnace brand and your home size. Large homes may require zoned HVAC systems, which cost more. Installing a highly efficient furnace averages around $6,150, but it’s a worthwhile investment as it can last 15 to 30 years with proper maintenance.
