How much does a gas furnace cost in Kansas? Well, that depends

You’re a savvy shopper.

You want to know the price of a new gas furnace for your Kansas home so you can get the best deal, right?

But answering that question is tricky. It’s like answering, “How much does a house cost?”

Of course, the answer is “It depends.” But that answer is about as helpful as a wet blanket in winter.

So, here’s a price range: an installed gas furnace in Kansas can cost on average $2,300 to $5,700+.

That cost is determined mostly by these 4 factors:

  • Energy efficiency (AFUE)
  • Comfort features
  • System size
  • The furnace installer your hire

Read on to learn how the above options affect the final installation price.

Cost factor #1: Energy efficiency (AFUE)

AFUE is basically the MPG of the furnace. The higher the AFUE, the more efficient the furnace is—and the more it costs.

Furnace efficiencies come in 2 main categories:

  • Conventional (mid-efficiency) furnaces: 80%-84% AFUE
  • Condensing (high-efficiency) furnaces: 90%-98+% AFUE

There’s a big cost difference between the 2 efficiency levels. Partially because condensing furnaces cost more to install since they create condensation in the heat exchanger (thus why they’re called “condensing” furnaces) and thus need a drain line installed with it.

Cost factor #2: Comfort features

Just like cars have sun roofs and seat warmers, furnaces have their own features that affect how comfortable you are. Of course, they also increase the price.

These two comfort features highly affect the final cost:

  • The blower type— Circulates air in your home
  • The burner type— Controls the flow of fuel

High-quality blowers and burners provide more even heating throughout your home (as in, there are fewer cold spots).

Here’s a rundown on all your options.

Blower types from worst to best:

  • Single-speed: Blows air at full blast or not at all.
  • Multi-speed: Blows air at low, medium or high speeds, depending on what you need. It’s just like your ceiling fan, but works automatically.
  • Variable-speed: Incrementally adjusts airflow based on your heating needs.

Burner types from worst to best:

  • Single-stage burner: Provides heat only at full blast or not at all.
  • Two-stage (or dual-stage) burner: Runs at a high or low setting. The low setting keeps the heat in your home from dropping too low below your thermostat setting.
  • Modulating burner: Adjusts precisely to meet your heating needs, keeping your home’s temperature constant. Keeps you comfy and keeps your heating bills low.

Cost factor #3: System size (BTUs)

Just like every foot needs the right size shoe, every home needs the right size furnace.

Bigger furnace = more expensive furnace.

However, you don’t have to worry about what size you need. A furnace installer will determine that for you by performing a Manual J Heat Load Calculation.

Speaking of installers…

Cost factor #4: The furnace installer your hire

Probably the biggest X factor is the person who installs the furnace. Quality of the installer and their pricing methods can swing the installation cost up or down.

A poor quality installer can cost you less upfront but more in the long run if they have to come back and fix their mistakes.

But how do you know who is “high quality”?

Finally, keep in mind how the installer charges: Hourly or flat-rate:

Hourly pricing

  • For efficient, honest installers, hourly pricing can save you a good bit of money.


  • For inefficient, dishonest installers, hourly can end up costing you more than average. Make sure you’ve found a good contractor if they bill by the hour.

Flat-rate pricing

  • You know exactly what the job costs before any work begins. So there are no surprises for you.
  • Flat-rate installers usually have standardized their installation process, meaning they’re less likely to make costly mistakes.


  • The flat-rate price is usually adjusted to be higher than average to cover any issues the installer has during the installation, ensuring they make a good profit.
  • Flat-rate may encourage the installer to rush to get the job done, which can lead to mistakes.
