While it’s considered impolite to inquire about a woman’s age, the same does not hold true for your air conditioner! As responsible homeowners, we strongly encourage you to know precisely how old your air conditioning unit is. Although it may appear trivial, being aware of the age and condition of your HVAC units is of significant importance. Why? If you’ve noticed a recent decline in your AC’s efficiency or experienced other issues, now is the ideal time to ascertain the cooling unit’s exact age. Air conditioners generally have a lifespan of 15-20 years, contingent on proper maintenance. Therefore, understanding your AC’s age will play a pivotal role in preparing you to make essential choices, such as determining if repair is the best course of action or if opting for a replacement would be more prudent. 

Follow these steps from the seasoned experts at Hilliard-Dublin Heating & Air to determine the precise age of your air conditioner: 

Finding the Manufacture Date on the Condenser 

Our initial step involves venturing outside to inspect the outdoor unit, also known as the condenser. This large metal box can usually be found in the backyard or occasionally on the side of the house. Look for a metal nameplate on one side of the unit containing information about the AC. Direct your attention to the top of the nameplate, where the manufacture date is often displayed in the upper right-hand corner or labeled as MFR DATE. Should you not find it immediately, there’s no need to worry; simply proceed to step number two below. 

Finding the Manufacturer Date Online 

If, for any reason, you haven’t found the manufacture date just yet, go ahead and make note of the unit’s model, brand, and serial number from the nameplate instead. Alternatively, you can quickly capture a picture of the nameplate for ease of reference. Then utilize any reputable online search engine to input these three details along with the phrase “manufacture date” in your query. Doing so will generate several websites providing comprehensive directions on decoding the manufacture date specific to your AC model. With a bit of investigative work and determination, you’ll successfully unveil the exact age of your air conditioner – congrats!
