How Long Should a Furnace Last? 

Factors Affecting Furnace Lifespan

Not every furnace is built the same, installed the same, or maintained the same. Most furnaces can last 10-20 years, depending on several factors.

• Type Of Furnace: One of the biggest factors in your furnace's lifespan is the fuel it uses. Gas furnaces generally have a shorter lifespan (10-15 years) compared to electric furnaces (15-20 years).
• Regular Maintenance Practices: A little TLC can go a long way. Routine seasonal maintenance is an easy way to protect your system and add years to its life. Additionally, be sure to change air filters every 90 days to increase efficiency and minimize your heater's workload.
• Usage Patterns & Environmental Conditions: In areas with cold, snowy winters, like Hudson, you're likely to run your furnace consistently. Frequent use over time can strain your system and shorten its lifespan.
• Proper Installation & Initial Condition: Successful performance starts on the day your furnace is installed. Proper installation ensures optimal performance and longevity.

Extending the Life of Your Furnace

Replacing your furnace is no small investment! Being mindful of your current heater's condition and implementing actionable tasks will help extend its lifespan. Remember: it's never too late to start caring for your furnace! Even a seven-year-old unit can benefit from routine care.

How can you help your furnace last longer? 

• Schedule regular maintenance with qualified technicians to inspect and tune up your furnace before winter.
• Change air filters regularly to maintain airflow and efficiency. Most air filters should be changed every 90 days, though you might change them more frequently if you have pets or allergies.
• Keep vents clean and clear to prevent your furnace from overheating.
• If you notice any unusual noises or performance issues, call for help as soon as possible. Odd noises indicate a problem with the unit that may cause damage or become a safety hazard if ignored.
• Avoid overloading your furnace with excessive or uneven usage. Set the thermostat at a manageable temperature that your furnace can keep up with.

When to Consider Furnace Replacement

While proper maintenance can extend furnace life, there are instances when replacement makes more sense than repair. Here are some things to consider when deciding to upgrade your furnace.

• Age: If your furnace is between 10-20 years old, replacement is on the horizon. We recommend consulting a professional to determine how much longer your furnace has.
• Frequent Repairs: If you constantly call for furnace repairs, it may be more cost-effective to invest in a new unit.
• Reduced Efficiency: If your energy bills have skyrocketed and your furnace doesn't run like it used to, it may be time to retire it.
• Safety Concerns: Gas leaks, pilot light problems and carbon monoxide emissions should always be handled by a professional. In some cases, the unit may need to be replaced instead of repaired.
