Is a High Efficiency Gas Furnace Worth the Money in Kansas?
February 13, 2015
Long story short: Yes, it’s worth it if you’re willing to wait for the high-efficiency furnace to pay itself back.
But how long does it take for a high efficiency option to pay itself back?
Here’s a simple method:
- Learn the extra upfront cost of the high-efficiency furnace
- Determine annual savings of the high-efficiency furnace
- Determine the payback period
Let’s go into more detail about each step.
Step 1: Learn the extra upfront cost of a high-efficiency furnace
First, get installation estimates for both:
- Mid-efficiency furnace (80% AFUE)
- High-efficiency furnace (90%+ AFUE)
A high-efficiency furnace not only costs more than a mid-efficiency furnace, but the installation cost is also higher because a new PVC flue pipe needs to be installed.
Let’s assume that the high-efficiency furnace (with installation) costs $1000 more than the mid-efficiency furnace (with installation).
Step 2: Determine annual savings of the high efficiency option
Compare how much you’ll save with a high-efficiency furnace compared to a mid-efficiency furnace each year.
Here’s where things can get very “math-y.”
So, to save you the trouble, ask for annual saving estimates for each furnace from a contractor while they’re giving you installation estimates.
For simplicity’s sake, let’s assume, that a high-efficiency furnace saves you $100 more a year compared to a mid-efficiency furnace.
Step 3: Determine the payback period
Now you know the high-efficiency furnace’s extra cost ($1000) and how much it could save you a year ($100).
Let’s calculate the payback period.
Since a furnace on average lives 18-20 years, the high-efficiency option will pay for itself with several years to spare to save you even more.
Of course, if you’re looking to move out of your home in a few years, you’d go for the mid-efficiency option.
Again, this is very, very simplistic example. We’re just giving you a method for calculating payback. So don’t take the numbers we’ve provided as gospel.
The key: find a good contractor
