How old is your furnace or air conditioner? Is it time to upgrade to a high efficiency furnace air conditioner?
High efficiency furnace air conditioner
Heating and Cooling systems need to be upgraded to new high efficiency furnace air conditioner units on average 15-20 years from the installation. Knowing the age of your furnace and/ or air conditioner will help in determining if a new high efficiency furnace air conditioner should be in the budget this year. Most of the newer units have a manufacturer’s date listed somewhere on the furnace/air conditioner; older systems may require a bit more digging. You can look at the serial number, which tells the manufacturer various pieces of information, including the age. Finding the serial number, however, may also require a bit of work.
Here are tips on determining your furnace and air conditioner age
- Look on the furnace surface/air conditioner for a paper or metal tag that contains a serial number and/or the manufacturer. This may also show an actual manufacturer’s date, depending on the manufacturer of the furnace/air conditioner. Turn off the power to the furnace/air conditioner – by either turning off the power switch or the master fuse to the unit — and look at the fan and fan blades. Older systems sometimes had the serial number stamped onto the fan itself, giving the necessary information even when a manufacturing label is absent. Look at the first four digits of the serial number once you find it. The first two digits can be the week of the year that the unit was manufactured, with the third and fourth number indicating the year. A serial number starting with 0193, for example, may have been made the first week of 1993. Some manufacturers have it the opposite way, first 2 digits are the year of manufacturer and second 2 digits are your week. Newer high efficiency furnace air conditioner often have installation date on the sticker.
- Look for a sticker or tag that gives a date when the furnace/air conditioner were last serviced. This is usually common on gas furnaces/air conditioners and may list the date that the systems were installed. This can often give a close approximation of the units’ age.
- Call the manufacturer to get the age of the systems. Even without a serial number, a manufacturer’s rep may be able to look at a picture of the units to give an idea of the period in which they were manufactured.
- If the company is out of business, having a home inspector or heating contractor look over the unit may be worth any fee charged to do so.
- If your utility bills have raised dramatically over the years this could be a sign that your furnace and air conditioning units are old. Even if your furnace/air conditioner has a few years left in it, it may not be cost efficient to keep it. If your energy bills during the heating/cooling season are high due to the systems’ horrible efficiency, its time to get new high efficiency furnace air conditioner installed.
