Where to find the serial number on a Carrier
On an outdoor AC or heat pump, the rating plate is on the side of the cabinet near the copper lines. On a furnace, remove the upper front door; the label is on the inside wall or the door itself.
Tip: in a dark basement or closet, take a photo of the label with your phone's flash on and zoom in on the photo.

Common questions about Carrier equipment
Where can I find the Carrier serial number on an outdoor AC condenser?
On outdoor Carrier AC condensers and heat pumps, the aluminum data plate is positioned near the electrical disconnect and refrigerant service valves on the side of the unit casing.
What is the typical lifespan of a Carrier residential HVAC system?
Carrier residential systems typically last 15 to 18 years with annual preventative maintenance. Systems operating in high-salinity coastal areas or extreme hot climates have an average lifespan of 12 to 14 years.
How long does a Carrier furnace, AC or heat pump last?
About 15 years on average. Units that get yearly maintenance often last longer; units in hard-water areas, coastal air or unconditioned spaces often fail sooner.
Is the serial number the same as the model number?
No. The model number describes the product line, size and options. The serial number identifies your exact unit and contains the manufacture date. Both are printed on the same rating label.
How accurate is this age estimate?
The date comes from the published serial number formats for each brand. It is the factory date, not the installation date, and some formats repeat every 10 or 20 years. If the label shows a printed MFG. DATE, that date wins.
