The HVAC Experts in Lebanon, OH


Your furnace plays a crucial role in maintaining a warm and comfortable home environment, especially during the cold winter months. However, like any significant household appliance, furnaces have a limited lifespan. Therefore, whether you’ve recently purchased a new home or are currently managing an aging furnace, it’s essential for homeowners to have a clear understanding of its age. This knowledge empowers you to proactively handle maintenance, address potential repairs, and plan for future replacements. 

In this informative blog post, Lebanon Heating & Cooling will provide various techniques that can be employed to discover the age of your furnace. 

Do You Know Why Your Furnace’s Age Is So Important? 

Having a clear understanding of your furnace’s age is of utmost importance for several compelling reasons. Each of these factors plays a crucial role in ensuring the optimal functionality and long-term durability of your heating system. 

  1. Maintenance: Regular maintenance is crucial to ensure the efficient and safe operation of your furnace during colder seasons. Plus, it’s good to know the age of your furnace because when you schedule your seasonal maintenance appointments, it’s beneficial for the HVAC technician to know the approximate age of your heating unit ahead of time. 
  1. Repair: When facing operational issues with your furnace, it is crucial to consider its age in order to determine whether investing in repairs or acquiring a new unit would be a more cost-effective solution. 
  1. Replacement: Most furnaces generally have a lifespan of around 15 to 20 years. Therefore, if your furnace is approaching or has surpassed this timeframe, it is advisable to proactively consider making arrangements for a replacement to avoid any unforeseen interruptions down the road. 
  1. Warranty: Most furnaces have manufacturer warranties, usually with a specified validity period. Hence, knowing how old your unit is helps determine if any warranty coverage is still applicable. 

Did You Look Inside the Owner’s Manual?  

To quickly determine the age of your furnace, try looking in the owner’s manual. This resource usually includes important information about the installation or manufacturing date, providing an estimate of your unit’s age. So, if you have the manual, check the introductory section or a dedicated “Specifications” page for this information. 

Did You Look for the Manufacturer’s Label? 

In cases where the owner’s manual is misplaced or does not provide the necessary information, an alternative approach is to examine the manufacturer’s label affixed to the furnace. This label is typically located within the furnace cabinet or along the unit’s side and contains crucial details, including the model number, serial number, and manufacturing date. The manufacturing date can be determined from the serial number, which may consist of a sequence of letters or numbers indicating the date. However, it is important to note that different manufacturers may use different coding systems. Some manufacturers utilize a simpler format for the date of manufacture, such as “MFG Date: MM/YYYY.” 

Did You Call the Manufacturer? 

When the serial number or manufacturer’s label does not clearly indicate the age of the furnace, contacting the manufacturer directly is another recommended approach. Reputable furnace manufacturers usually have a dedicated customer service or support team that can help you determine the age of your unit based on the serial number or other unique identifiers. 

Did You Book Your Seasonal Checkup? 

Lastly, an HVAC technician can perform a thorough evaluation of your furnace and reveal its age. Typically, during regular seasonal furnace inspections, the technician can easily determine the manufacturing date and provide valuable insights into the furnace’s condition and expected remaining lifespan. This is another reason why we consider consistent seasonal checks to be an effective strategy for maintaining your furnace’s optimal condition. 

Having knowledge of your furnace’s age is crucial for ensuring the comfort and warmth of your home, especially during the coldest months. To avoid any inconvenience caused by a malfunctioning furnace when you need it the most, it is recommended to take proactive measures to determine its age and make informed decisions about your heating system.
