How old is my Trane furnace or AC?

Type the serial number from the Trane label to see when it was built.

Scan insteadWhere is the label?

Example

1447B2BP1X
  • 14Year: 14 = 2014
  • 47Week: 47 (around November)

Built Week 47 of 2014 (around November)

11 years, 11 months old

Plenty of life left. Well inside the usual 15 to 25 year lifespan.

Keeping it going

  • Change or clean the air filter every 1 to 3 months. A clogged filter is the most common cause of strain.
  • Keep 2 feet of clear space around the outdoor unit and hose the fins off gently each spring.
  • A yearly tune-up catches small problems, like a weak capacitor, before they become a no-heat or no-cool call.
  • Some home insurers and home buyers’ inspectors ask the age of the HVAC system. Florida 4-point inspections record it.
  • Most HVAC parts warranties run 5 to 10 years and require registration within 60 to 90 days of install. Check with the installer.

Reading a Trane serial number

Since 2010 the serial has 10 characters and starts with two year digits and two week digits. From 2002 to 2009 it has 9 characters and starts with one year digit.

From 1983 to 2001 the serial starts with a year letter. Guides disagree on S and Z, so the checker shows both dates for those.

Trane year letter and week

Used 1983 to 2001. Example: G03504353
