Indianapolis, IN, has lower living costs than the national average, making furnace and AC replacements more affordable for homeowners. The type of HVAC system and the size of your home are the two main factors that will influence the price. Let’s review how to determine the cost of replacing your furnace and AC in your Indianapolis, IN home.

Furnace and AC Replacement Cost Factors

Furnace and AC replacement costs in Indianapolis, IN, vary significantly depending on the type of HVAC system, the brand, and the size. 

Type of HVAC System

There are four types of HVAC systems, including split systems, duct-free systems, hybrid systems, and packaged heating and air systems. Split systems are common in Indiana homes, but hybrid systems are increasing in popularity due to the region's harsh winters and the unit’s high-efficiency heating capabilities. A hybrid system will automatically switch from the electric pump to the gas furnace when temperatures drop below freezing. ​It’s best to consult a HVAC pro to determine which type is best for your home.

The typical cost ranges for each are:

Unit Size

The square footage of your house will determine what size furnace and air conditioner you need to heat or cool your space efficiently. A local HVAC company can help you determine what size you need exactly by doing a load calculation.

Unit Brand

An HVAC system costs about $4,500 on average, but the brand you buy can change this number. For example, brands like Amana or Coleman tend to come in the lower end of the spectrum at $2,850, while brands Trane and York are often $5,700 or more.

HVAC Pro Costs

Hiring an HVAC pro in Indianapolis can cost between $500 to $2,500 per unit or $75 to $150 per hour. The price will depend on the size of your home, the type of unit, and the complexity of the job. However, it’s vital to hire an experienced pro to replace your furnace and AC system because they will ensure the job is done safely and efficiently. 

Permits

The city of Indianapolis requires a permit for HVAC installation. According to the Department of Business and Neighborhood Services, a permit will cost between $150 to $190, plus $23 for each additional 1,000 square feet. The price will depend on your home's square footage, and the pro should obtain the necessary permits before starting the job.

Taxes

You will need to allocate an additional 7% of your budget to cover the sales tax for the materials and equipment. So if the price of the materials and HVAC unit is the average cost of $7,178, the taxes would be an additional $502.46.

Does Replacing Your AC and Furnace Increase Home Value?

Replacing your HVAC system can increase your home's value by 5% to 7% and offer a return on investment of about 30%. A properly functioning HVAC system is typically a “must-have” for homebuyers in Indianapolis due to the region's frigid winters and sizzling summers.

A home with a broken HVAC system could see a 10% drop in sale price, so replacing your furnace and AC can prevent your home’s value from decreasing. Having a new HVAC system installed will make your home much more appealing in Indianapolis’ competitive real estate market.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
