Why Would I Need The Model/ Serial Numbers? An example would be 0508 which means the furnace was made on the fifth week of the year 2008. The first two numbers from 01-52 tell you the week of the year it was made while the last two numbers tell you the year it was made. The first 4 digits tell you when your furnace was made.

Some manufacturers achieve this by using a letter in their model number but Carrier uses a 4 digit numbering system. It also tells you the week and year that your furnace was made. The data sticker tells you more than just the make and serial number. Once you have the model and serial number of your machine you can either replace the cover to the furnace or leave it removed if you’re expecting to have to open it again. The two most common location for Carrier to place their data stickers is in the top left corner or centered on the bottom of the furnace under the burner.

It helps to have a flashlight with you especially if your furnace is located in a darker than average place. Once you have the cover off of your furnace you need to find the data sticker. You can either lift it straight off the unit or it may be secured by some sort of screw or another kind of fastener. Once you have located your furnace you are going to want to remove the vented cover plate on the front of the unit. You will have to remove the cover of your furnace to access it but this is easily removed and replaced. The model and serial numbers can both be found on a data sticker on the inside of your furnace on the top left side or under the burner. If you have ever needed to service your furnace or pickup parts for it you know how important it can be to know your furnace’s model and serial numbers.
