How Can I Age My Carrier Furnace, Air Conditioner, and Heat Pump?
Modern Carrier equipment (that would be all gas furnaces, air conditioners, and heat pumps) use a four-digit number as the first four places of the serial number for the age of the equipment. In the example below, this unit is a 2017 model.
It’s also important to note that modern Carrier equipment will also have a box printed on the data plate label with the month and year it was manufactured. The example below has it listed as JUN 2017
HOW CAN I AGE MY CARRIER HVAC EQUIPMENT USING THE SERIAL NUMBER?
Older Carrier equipment used a different format with their serial numbers. This style was utilized from the early 1960s through the late 1980s. Very few pieces of this old stuff are still in use today, but if you happen to have one still running- good for you! The layout on the old serial number was a single letter and then a single number. The number digit ran in a 10-year cycle, so it can be hard to figure out exactly the manufacture year.
EXAMPLE: G6xxxxxxx
This unit could be 1966, 1976, 1986. Most of the time you can look at it and tell roughly how old it is. If you still can’t tell how old it is, look for the ANSI (American National Standards Institute) number which should be printed on the label (along with the year). This is the standard in which the unit was produced, and is typically just a few years younger than the manufacture date.
Hi Ben. I have a Carrier Air handler 1986 Model. The heating element only heats partially.
So, can I replace the element with a compatible one, or can it be re-strung?

Is it an electric heat air handler? You’ll want to have an amp draw test performed on the strip heat to see how much current they are pulling. This will help determine which ones are faulty. Keep in mind that a 40+yr old unit is WELL beyond the normal lifespan, and I wouldn’t sink too much money into it. At some point, you’ll need to have it replaced.
Hey Ben, impressive write-up here. This information really helps us carrier customers but it can also be used for other brands as well. Great info to keep in mind, thanks.
Hello, I live in an apartment complex & the humidity inside seems to be high. The serial number on my heat pump is 4186A 25463. Does that mean it was manufactured in 1986?
