2 Signs it's Time to Replace Your HVAC Unit
Thursday, January 05, 2017
Outdoor Unit


Unfortunately, heating and air conditioning units don't last forever. Is it time to replace your HVAC system? You don't want an older system to give up in the sweltering heat of high summer or the intense cold of winter. Here are signs that can help you decide if it's time to replace that old unit.

How Old Is It?

The average age of a furnace is about 15 to 20 years, while an air conditioner usually gives up a bit sooner, at about 14 to 16 years of service. To determine the age of your existing system, look at the serial number on the manufacturer’s label. Sometimes this is straightforward; other times, it takes some research. 

For instance, on a Carrier HVAC unit made in the last 25 years, the serial number will consist of four numbers, a letter, and five more numbers. The first two numbers designate the week of creation, and the next two numbers show the actual year. (Any serial numbers different than this mean the HVAC unit is at least 28 years old, and forced replacement is imminent!) 

If the second set of numbers on the serial number show the unit to be 16 years of age or older, it's time to replace it.

Energy Bills Going Up

Are your cooling and heating costs going up? That's another sure sign it’s time to replace your HVAC unit. Older units lose efficiency over time as their parts wear out. Those older parts will use more energy as they age. 

Look closely at the energy usage on your utility bills to find out if you’re using more energy than you used to (and to determine if the higher cost isn’t due to price increases). Many utility companies compare year-to-year usage on the monthly bill. If your energy costs are rising but the weather conditions are staying pretty much the same as they were last year, it’s time to look into getting a new HVAC unit.
