You probably don’t think about your furnace until it acts up or stops working if you’re like most homeowners. One of the first questions on your mind is probably “how old is this thing?” when that happens. Though there are a few ways to do it, determining the age of your furnace can be tricky. Today, we at Air Supply Air Conditioning & Heating would like to discuss how you can find out how old your furnace is.
Furnace Manufacturer Label
Looking at the manufacturer’s label is one way to determine your furnace’s age. It is frequently affixed to the front of the unit, and the label is typically included on newer furnaces.
Serial Number. You can also look for a serial number if you can’t find the manufacturer’s label. A label that includes information about the equipment’s energy usage, manufacturer, etc., and this number is usually located on the furnace’s rating plate. You may need to check the front, back, sides, top, or inside of it as the rating plate can be located in any number of places depending on what make and model your furnace is. You won’t need to worry about the serial number since the rating plate will also list the date of manufacture in some cases. You will need to “decode” it when you find the serial number. Each HVAC manufacturer arranges its serial numbers differently. For example:
Lennox: With four numbers followed by one letter, many of these systems have serial numbers. Representing the factory where the unit was manufactured are the first two numbers. The second two numbers are the year in which the unit was manufactured. This would mean that your unit was made in the year 2010, 12 would refer to the factory if your unit’s serial number is 1210B12345, for instance.
Bryant/ Payne/ Carrier: To show the week and year the unit was made; this manufacturer often uses a serial number. The first two digits of the serial number represent the week of the year. The year is represented by the second two digits. A Carrier furnace with serial number 0205 was made during Week 2 of the year 2005 for example. You can search online for “how to read a manufacturer furnace serial number,” and the result should appear towards the top of the page if you don’t know how to decode the serial number. They should be able to provide you with your unit’s age, you can also contact the manufacturer and provide them with the serial number.
Furnace Warranty Information
By looking at the warranty information is yet another way to determine the age of your furnace. It will likely have the date of purchase listed on it if you have a copy of the warranty. If they have a record of when your furnace was purchased, you can also check with the manufacturer to see.
Furnace Maintenance or Service Tag
Stating when the equipment was last maintained or serviced, some HVAC contractors leave a tag or a sticker on the unit. As it should be close to the date of manufacture, sometimes this tag also lists the installation date.
Since they should have a record of the installation and information about the equipment they installed for you, you can always try calling up the HVAC contractor who installed your system if it doesn’t.
Contacting Furnace Manufacturer
If all else fails, you can try getting in touch with your furnace’s manufacturer. You can provide them with a picture of the unit and the rating plate if you’re unsure what the serial number is, and they may be able to use that information to identify your furnace and tell you its age.
