Every product has an expiration date. As far as furnaces are concerned, it would be useful to know exactly the time period for which they are estimated to work properly, while also knowing a few things about increasing their longevity and functionality.
Although some furnaces can last for 40 years, the average lifespan of a furnace is that of 15-30 years. If you do the yearly maintenance, your furnace should last longer than 15 years.
The longevity of a furnace depends on certain factors. First of all, it is the furnace model that influences its durability. Newer models typically have longer lifespan than older models.
The frequency and quality of furnace maintenance by HVAC companies such as Pasterkamp also determines its lifespan. A yearly maintenance can help you keep your furnace clean and working properly.
The level of moisture and type of ventilation also determine how long your furnace will work properly. Humidity can cause rust-related issues. At the same time, a proper installation can certainly add years to your furnace. A defective installation can lead to efficiency-related issues, such as comfort level, air distribution, premature breakdowns, and so on.
For more information about the exact lifespan for your furnace, there certainly are many experts in your area who can give your proper guidance.
