How Can I Determine My Furnace’s Age?

There are many things to consider when settling into a new house. This also entails determining what future improvements or adjustments may be necessary for some homeowners in heater repair Fishers.

It should be on your list of prospective responsibilities, even though you might only occasionally think about your furnace and cooling system, unless they require frequent furnace repair.

How Do You Figure Out How Old Your Furnace Is?

Condenser nameplate: The enormous metal condenser box outside your house has a nameplate for each furnace. The unit’s nameplate shows the production date in the upper-right corner. Finding the brand, model, and serial number on the plate will always allow you to determine the condenser age.

Product label: The system’s age can be ascertained without a manufacturing date. Record the model and serial numbers. Although they might not seem pertinent, they provide the manufacturing date information. You may get the production date online by entering the numbers and the brand name of the furnace without having to interpret the data.

Date of installation: Your equipment’s production date and installation date will often be the same. By verifying its age, customers can determine whether to replace or go for furnace repair in Fishers, IN.

Check the door: Remove the furnace’s detachable door from the outside. Look inside the door to locate the label or tag that includes the serial number for your furnace.

Check the fan: After turning off the source of electricity, check the fan and its blades. Even without a manufacturer’s label, older furnaces may have the serial number stamped on the fan, providing the necessary information.

Year and week as the initial four digits: The serial code’s first four digits represent the production week or month, followed by the year. If you find 1-4-9-9 followed by other numbers or letters, it could mean that the furnace was built during the 14th week of 1999.

The date is at the end: The final four digits of the serial number appear sporadically but infrequently, indicating the model’s production date.

Letters that stand for months or years: One letter could represent the month or year in various ways. A serial number can, for instance, take the form 05B, where 05 stands for the year 2005 and B for February.
