When to Replace Your Furnace?


The average life expectancy of a furnace is between 10 and 15 years. This, however, does not mean that you will need to replace your current system when it hits the age of 10 if your furnace is still running well and there aren’t any problems with it, then you could end up spending more money than necessary.

One important factor that you should consider when deciding whether or not your furnace needs to be replaced is the amount of energy it uses.

If you have a furnace that’s more than 15 years old, it’s likely to be using close to twice as much energy as a system of equal size from a modern manufacturer. As a result, you’ll find that your energy bills are higher than they should be.

Another factor to consider is the overall efficiency of your furnace. If it’s an older unit and its efficiency rating is below 80%, then you’re going to end up spending more money on heating bills as well. In many cases, replacing a furnace that’s more than 10 years old can lower your energy bills by up to 20%.

Furnace replacement is not something you should take lightly, but if you do your research and manage to find a good furnace at the right price, then it could result in savings of hundreds of dollars per year.

When you’ve determined that replacing your current furnace is the best option, there are a number of factors you’ll need to consider.

Your current system may occupy more space than your new one. If you’re replacing a furnace with a central air conditioning unit, then you’ll need to consider this as well. You may want to replace all of the ducts in order for your new system to work most efficiently.

Your current unit may be more expensive to maintain than an energy-efficient new one. You can calculate what it will cost you in the long run by multiplying your present monthly energy bill by 10 years and comparing this number to what a new system would cost you.

Current systems that are more than 10 years old don’t meet newer, stricter efficiency standards. If you want to reduce your carbon footprint and help the environment, then replacing your unit is one way to do it.


Replacing your current furnace with a modern unit can result in substantial savings on energy bills and an overall increase in the value of your home. For more information, contact a knowledgeable heating contractor like Lucky Air Inc.
