Since so many factors are involved, there is no firm answer for what is the life expectancy of a forced-air furnace. Even if there is a fixed amount of time, it can’t be guaranteed.
A furnace will likely need replacing eventually, even if the right circumstances and care are implemented.
As the name suggests, hot air is used to distribute heat throughout a house with a forced-air furnace. Cold air is sucked into the furnace through the cold air intake vent. Afterward, heated air is circulated through another set of ducts.
Furnaces often stop working abruptly with no warning signs of a malfunction. You need to plan to buy a new furnace if your furnace is nearing its end of life. This will help you to prevent a sudden breakdown of your furnace.
It is usually possible to expect a furnace to last anywhere from 15 to 20 years. When the repair costs of your furnace are greater than the price of buying a new one, then you should replace it.
Life expectancy of forced air furnace varies based on several variables, for instance –
- Unit quality
- Usage frequency
- Routine maintenance
- Unit type
What Are Factors Limiting Your Furnace Life?
The lifespan of your furnace is affected by a variety of factors.
- Model of the furnace
You should always buy the most modern furnace you can find. Old models have a shorter life expectancy.
- Installed poorly
Ensure that the furnace is installed properly by a licensed professional. This way you’re covered under the warranty that ensures that faulty installation will not lead to problems.
- Improper maintenance
At the very least, service your forced air furnace every two years to ensure it is operating properly.
- Inadequate ventilation
Be sure that you allow enough space and ventilation before you install a furnace. Poor airflow and excess moisture lead to the damage of heat exchangers.
