When looking at purchasing a new home or inspecting your current appliances it is important to know how to tell the age of the appliance and what its average life expectancy is.
Most manufactures don’t simply put the manufactured date on the data tag but instead have the date in the serial number. A reliable website I always use for HVAC and water heaters is https://www.building-center.org/.
The image at the end is an example of a Lennox HVAC where the 3rd and 4th number represent the year of production.
Typical Life Expectancy
• It is highly recommended to get your furnace and air conditioner serviced annually. This step will prolong its life and is well worth the servicing cost.
• When your air filters are worn or dirty, your system has to work harder to push air through. This means that your system is expending more effort than necessary. Also, dirt and grime can end up clogging up your HVAC system components.
