Normally the first two digits in a unit, serial number, or the year of manufacture, with the following two digits being the month or the week but if you simply google how to read whatever brand you have serial number it will then tell you how to decipher the numbers on the serial to give you the exact age of the furnace so that you know when it’s getting time to start thinking of replacement

Does the Age of My Furnace Matter?

The age of your furnace matters because outdated heating units often don’t work as well as newer models. Older furnaces are prone to many issues, including worn-down parts and inconsistent cycling. Knowing the age of your furnace helps you make critical decisions, like scheduling maintenance or saving for a new installation. 

On average, traditional furnaces last anywhere from 10 to 20 years before problems set in. Furnaces that are more than 20 years old usually require a replacement unit. Without replacing your outdated furnace, you’ll face ongoing repairs and poor performance. 

According to Energy Saver, modern furnaces operate at 98.5% efficiency, while older models operate at around 56 to 70% efficiency on average. For example, EnergyStar-rated furnaces require far less energy to maintain the same temperatures as old units, making them a great way to improve your home’s sustainability.

So, what if your old furnace is working perfectly fine? Does replacing it still make sense? There are several benefits to having a newer heating unit installed, including the following:

  • You’ll save money on repair costs and ongoing maintenance.
  • Upgrading to an electric system or heat pump improves your system’s energy efficiency.
  • Electric heating units last significantly longer than traditional gas units (30 vs. 20 years).

While it seems like a big undertaking, having a professional like JC Mechanical install a new furnace is a good idea if your current unit is 15 to 20 years old. You should save money in the long run by avoiding unnecessary repairs between maintenance appointments.

How Do I Tell How Old My Furnace Is?

Are you unsure how old your property’s furnace is? If the furnace was already in place when you moved into your home, you probably have no idea how old it is unless there’s documentation confirming the date of installation.

Some investigation might be in order to find this information, but it’s simple if you know what to look for. Take the following steps for how to tell how old a furnace is:

Look for the Furnace’s Manufacturer’s Label

The easiest way to find out the age of your furnace is by looking at the unit itself. There should be a manufacturer’s label. Some units have a manufacturer label placed directly on the front of the unit with the date it was produced.

Locate the Serial Number

If there’s no manufacturer’s label information, the next thing you’ll look for is the unit’s serial number. The serial number is usually on the unit’s rating plate and gives you key information about the furnace’s energy use and manufacturer. 

The rating plate is located in several different spots, depending on the make and model of the furnace. Check the front, back, sides, and inside of the furnace unit. 

Once you’ve found the rating plate, deciphering the serial number requires a little work because every HVAC manufacturer arranges their serial numbers differently. For example, Lennox serial numbers contain four numbers and one letter at the end. The first two numbers refer to the factory it’s from and the second two refer to its production year (if it’s 1709, the furnace was made in factory 17 in 2009).

Another example is Carrier, which includes the week of production in their serial number. Say the serial number is 0713. This means your furnace was made in the seventh week of 2013.

Check Out the Fan Blades

If you can’t find the serial number on the rating plate, take a look at the fan blades inside the unit. Some manufacturers stamp the production date on one of the fan blades.

Search for the Warranty Information

Do you know how to tell how old a furnace is without the serial number? Try the warranty information. If you have a copy of the warranty, look for the year of manufacture and the date of purchase. 

In some cases, you can contact the manufacturer to see if they have a record of the purchase.

Check for a Service Tag

Some HVAC technicians attach a service tag to the unit during maintenance and repairs. This has the date of the last service and, in some cases, the date of installation. If the date of installation isn’t there, try contacting the HVAC company to see if they’re the same ones who installed the unit.

Signs

Your Furnace Is Nearing the End of Its Lifespan

If you’re unable to find the age of your furnace, it’s still helpful to look for a few signs that a  replacement might be coming up. Go through the signs of furnace failure below so that you can feel prepared:

Higher Utility Bills

Aging furnaces work harder to maintain the temperature in your home. This causes an increase in your utility bills during the fall and winter months.

Rusty Flue Pipes and Connections

Rusting around your unit indicates increased moisture and, inevitably, the corrosion of the unit. This is common in older units.

Constant Cycling

Furnaces aren’t meant for constant cycling like heat pumps. If your furnace is cycling nonstop, there’s something wrong with it. This is common in older furnaces struggling to maintain a certain temperature or housing a component that’s gone wrong.

Cold Spots Throughout Your Home

One of the biggest indicators of a dying furnace is inconsistent heating. Do you find that your living room is warm while your bedroom is freezing? A working furnace heats the entirety of your home consistently, not just certain spots.

Foul Odors

Your furnace shouldn’t produce any odors. Bad smells are a serious indication something is wrong, especially if it’s a rotten egg or sulfur smell that could mean a gas leak. It’s an emergency if you smell sulfur around your furnace, and you should evacuate and call for help immediately.

What If I Can’t Afford a New Furnace Installation Right Now?

Furnace replacements are a big expense for many homeowners, so it’s perfectly reasonable to wonder about whether it’s worth it. Rest assured, you may not need a new furnace installed the moment your current one turns ten years old. 

However, if you can’t get a new furnace right now and the old one is showing some signs of wear and tear, seek prompt repair services. Repairing existing problems as soon as possible prevents them from becoming larger ones and keeps your unit working for the time being.

Another good suggestion is staying on top of regular maintenance. Yearly tune-ups ensure your unit is in good condition and working properly. During your annual inspection, your technician examines your furnace from top to bottom, looking for any issues and resolving them right away.
