High-efficiency comfort built for Indiana winters.

What Is a Residential Gas Furnace?

A gas furnace burns natural gas to heat air, which is distributed through ducts by an indoor blower. It remains Indiana’s most common heating system because it delivers powerful, consistent warmth even during deep-freeze weather. Modern condensing furnaces capture heat that older units waste, cutting gas use and emissions while keeping homes quiet and comfortable.

Furnace Installation Cost in Bloomington

Most Monroe County homeowners invest between $3,500 and $10,000 for a complete installation. Cost varies with home size, efficiency, venting needs, and installation complexity. Standard 80 AFUE systems meet basic needs, but 99 AFUE ultra-high-efficiency models deliver the lowest long-term energy costs.

Understanding AFUE

AFUE (Annual Fuel Utilization Efficiency) measures how efficiently fuel becomes heat. An 80 AFUE furnace wastes about 20% of each gas dollar through exhaust. A 99 AFUE furnace converts nearly everything you pay for into usable warmth, losing almost nothing. That 19-point efficiency gap translates into about 20% less gas used every winter.

Local Energy Rates and Outlook

Bloomington homeowners currently pay about $1.25 per therm for natural gas and 13¢ per kWh for electricity. Over time, both typically rise 2–3 percent per year, though short-term spikes during extreme cold can temporarily send gas rates 30–50 percent higher. Efficiency is the only reliable shield against that volatility—once installed, it keeps saving every winter.

What You Can Expect to Save

A 95–99 AFUE furnace uses roughly 20% less natural gas than an older 80 AFUE model. At today’s rates, that’s about $175 to $225 saved per year on heating bills. Over 15–20 years—with average inflation and occasional cold-weather price jumps—that equals roughly $3,500 to $5,500 in fuel savings, before rebates or resale value.

Pair that with a variable-speed ECM blower motor, which cuts electricity use by about two-thirds, and you’ll save another $50–$100 a year in power costs while enjoying quieter, steadier airflow. Together, the upgrades pay for themselves in lower bills, reduced emissions, and dependable comfort no matter how harsh the winter gets.

What Types of Furnaces Are Available?

• Single-stage: One flame level, lowest upfront cost.
• Two-stage: Runs low most of the time, high only in extreme cold.
• Modulating: Adjusts in small increments, the quietest and most efficient.

When to Replace Your Furnace

• 16–20 years old or more
• Frequent repairs or rising utility bills
• Uneven heating or short-cycling
• Cracked heat exchanger or failed safety inspection
• Loud or irregular operation

Replacing with a 95–99 AFUE model restores comfort and safety while cutting monthly energy use.

Can I Finance a New Furnace?

Yes. We offer financing options (with approved credit) to spread out payments while upgrading your comfort and efficiency.

Rebates and Tax Credits in Indiana

Indiana utilities such as CenterPoint Energy and Duke Energy periodically offer rebates for ENERGY STAR-rated furnaces. Ecofriendly Mechanical confirms and applies every eligible rebate during installation.

Federal tax credits may also apply to qualifying high-efficiency systems and ECM blower upgrades.

Why Efficiency Matters in Bloomington

Super-cold winters can strain regional natural-gas supplies, forcing prices to spike. A 95–99 AFUE furnace permanently lowers fuel use and helps stabilize operating costs even during those peaks. Add an ECM blower and you gain extra electric savings plus smooth, quiet operation all season long. Efficiency isn’t just comfort—it’s insurance against energy volatility.

How Long Does Furnace Installation Take?

Most furnace replacements are completed in one day. Projects with duct or venting updates may take longer.

Do I Need New Ductwork with a Furnace Replacement?

Not always. Ecofriendly Mechanical performs static pressure testing and a full duct inspection during every furnace estimate. We check for air leaks, blockages, and undersized returns that can restrict airflow. In many Bloomington and Monroe County homes, a few targeted duct upgrades are all it takes to improve comfort and efficiency—no need for a complete replacement.
