The manufacturer makes residential and light commercial heating and cooling products, including central air conditioners, furnaces, and heat pumps. Armstrong furnaces were created in 1928 by the Lennox Furnace Company in Columbus, Ohio. Armstrong Air products are still proudly assembled in the United States, at facilities in Orangeburg, South Carolina.

Furnaces from this manufacturer utilize a smaller Btu input per burner of around 7,500 to 11,000 Btu per burner, instead of the traditional 20,000 to 25,000 Btu per burner. This makes for quieter furnace startup and operation without sacrificing heat output. By combining this lower firing rate with more burners and a larger clamshell heat exchanger, Armstrong Air furnaces deliver consistently quieter operation and greater durability.

Additional information on the Armstrong Air brand can be found on the Armstrong Air website at www.armstrongair.com/products/gas-furnaces.

The photo below shows the name plate label for an Armstrong Air furnace Model number A80UH1D070A12-02 and serial number 5911E06096.

Armstrong Furnace Serial Number Can Reveal Year of Manufacture beyond Armstrong Residential Furnace Model Number Description

One can determine the year that an Armstrong Air furnace or air conditioning unit was manufactured from the serial number on the furnace or air conditioner. If you want your Armstrong furnaces serviced in Omaha, then just call Accurate Heating and Cooling. We can service and install Armstrong air conditioners as well as Armstrong furnaces.

For units manufactured since the early 1990s, the serial numbers will indicate the year that the unit was manufactured. The third and fourth digits correspond to the year that the unit was built. For example, the photo of the Armstrong Air furnace from above shows a serial number of 5911E06096. The third and fourth digits are 11 such that the unit was built in 2011.

Another handy way to identify the year that the furnace or other HVAC appliance was manufactured is from consulting the Building intelligence Center website at http://www.building-center.org. Select the type of HVAC equipment interested in and then select the brand of equipment which is listed from a drop down menu in alphabetic order from the first letter of the brand name. Then select the particular brand of equipment desired. The various different serial number formats used by that brand are listed with the means of decoding that serial number format for the year of manufacture.
