Furnace Cost in Bloomington, IL

New Furnace Cost in Bloomington, IL

In Bloomington, you can expect a new furnace to cost anywhere from $5,800 to $10,300. This price includes installation.

The wide cost range is due to a few key factors. First, the size of your home as well as how old your windows/insulation are will influence what size furnace you need. The bigger the furnace, the more expensive the project. Second, the furnace type (single-stage vs variable-speed, for instance) and brand will also have a big impact on your project cost.

Check out the cost table below and/or use Modernize’s HVAC cost calculator to get a ballpark estimate.

Key factors impacting costs: attic/basement access to your furnace, venting path, if you need a new chimney liner, gas piping repairs or extensions, duct resizing or repairs, and condensate routing.

Must-Know Terms

There are a few key abbreviations and terms we used in the table above that you should understand in order to best estimate your own project cost.

BTUs are the unit of measurement used in furnace capacity. In brief, this is the furnace size. In Bloomington, a home between 1,600 and 2,400 square feet will need a furnace between 70k and 100k BTUs. The age of your windows and insulation can also impact the furnace size you need, as is mentioned above. You can read our guide to picking the right furnace size for a home in Illinois and/or check out Modernize’s furnace size calculator.

A furnace’s AFUE rating shows how efficient it is. A furnace with a 95% rating would successfully turn 95% of the energy it uses into heat for your home.

Furnaces come in single-stage, two-stage, and variable-speed models. A single-stage furnace is other fully on or fully off while the other options can more precisely target airflow to where it’s needed by running more often but using less energy. You can learn more about them (and other types of systems) by visiting our guide to home heating systems.

Utility Rebates in Bloomington For Furnaces

Utility Companies We Checked

• Ameren Illinois

We last checked for furnace rebates at this provider in September of 2025. During heating season, we will check monthly to see if rebates have changed. This section will next be updated with any applicable information in October 2025. Outside of heating season, this section will be updated along with the rest of the page every quarter.

Current Offers

Ameren does not currently offer any rebates for furnaces, unfortunately. They do have other discounts and rebates for energy-efficient home upgrades you may want to check out, including a rebate on smart thermostats for up to $125.

Labor Cost and Market Conditions

In McLean county, the median HVAC wage is ~$27–$31/hr. However, labor costs do not just cover the installer’s wage but also company overhead and profits. For that reason, you can expect this range to be doubled or tripled to reach an hourly labor rate for HVAC installation.

Be aware that, just like in the rest of the state, winter demand raises lead times and costs, too. If it’s possible to replace your furnace in the off-season instead, you may be able to get a better deal.

We build average furnace replacement costs in Chicago by using the following method:

• Equipment MSRP bands (70–120k BTU, multiple efficiency levels) adjusted to local freight / markup
• Labor component = crew hours × local fully-loaded wage (including benefits, overhead, profit)
