LG® HVAC age

How to determine the date of production/manufacture or age of LG® brand HVAC Systems.

The industry average service design life for most forced air furnaces is 15-20 years, and the industry average service design life for most air conditioning condensing units is 10-15 years. The average service design life of boilers can vary from as little as 10 years to as many as 50 years depending on the type and quality of materials used in their manufacture. Routine upkeep/maintenance, regional weather/climate, and location/placement of the mechanical systems will all play critical roles in the longevity of these systems.

Parent Company: LG Electronics

Subsidiaries or other related brands: LG

The date of production/manufacture or age of LG® brand HVAC equipment can be determined from the serial number located on the rating data plate or separate UPC tag below the rating plate.

Example serial number styles/formats found:

Style 1: 407HAVN79423 -or- 207KRMK0Y171
Style 2: EQ11220013150001

Legend: Year is RED; Month is GREEN; Day is BLUE

Style 1: 407HAVN79423 -or- 207KRMK0Y171

Year of manufacture can be determined by using the 1^st position of the serial number

Note that the decade is not distinguished. One must look for other cues to determine the decade. (HINT - Some units have a separate serial number tag from the main data plate/tag. The manufacture date may be included and often is on more recently manufactured systems.)

Month of manufacture can be determined by using the 2^nd & 3^rd positions of the serial number

The first example represents a manufacture date of 7^th month (July) of 2024, but could also be 2014. The listed manufacture date confirms 2024.

See example data plate photos below:

Style 1: EQ11220013150001

Year of manufacture can be determined by using the 6^th thru 10^th positions of the serial number

Month of manufacture can be determined by using the 11^th position of the serial number (1-9, A=Oct, B=Nov, C=Dec)

Day of the month of manufacture is listed in the 12^th and 13^th positions

Note:

This style believed to no longer be in use by LG
