Indianapolis, IN Furnace Replacement Service

Get a Quick Quote on a New Furnace System That Will Keep Your Home Warm All Winter

Most furnaces last around 15 years. Once yours gets close to that point, it’s a good idea to start planning ahead. Waiting until it breaks down can leave you without heat on the coldest night of the year and scrambling for emergency service. Replacing your furnace before that happens gives you time to choose the right system and schedule the work when it’s convenient.

Regular maintenance can help your furnace run longer, but eventually every system wears out. If you’re dealing with frequent repairs, uneven heating, or higher energy bills, those are signs it may be time for something new. Thiele Heating & Air Conditioning has been helping Indianapolis homeowners replace furnaces since 1883, with experienced technicians who know how to make the process much less stressful.

When you call Thiele, you’re getting more than just a new furnace. You’re getting a system that’s sized properly for your home, installed the right way, and backed by a local team you can trust for reliable furnace services year after year. Contact us today to schedule a consultation and learn about your options for residential and commercial furnace replacement in Indianapolis, IN, and the surrounding areas.

How Much Does a Furnace Replacement Cost?

Sometimes it’s because of a sudden breakdown, and other times it’s a project you’ve seen coming for a while. Either way, buying a new HVAC system can feel overwhelming—and choosing the wrong heater could mean higher bills, frequent repairs, or a home that never feels quite warm enough.

Most furnace replacements fall somewhere between a few thousand dollars on the low end and several thousand on the high end. We will give you an accurate cost during your consultation. The price depends on the type and size of the furnace, the fuel source, and any additional costs like new ductwork, thermostat upgrades, or air quality add-ons. That’s why we provide a clear in-home estimate, so you know what your project will involve before we start.

At Thiele Heating & Air Conditioning, our goal is to make this process as simple and stress-free as possible. We offer competitive pricing, convenient financing, and seasonal coupons to help make your new furnace installation more affordable. More importantly, we’ll help you choose the right system so your investment pays off in long-term comfort and energy savings.

How to Buy the Best Furnace for Your Indianapolis Area Home

Replacing your furnace is a big step, and it’s important to feel confident in the choice you make. A new furnace isn’t just another appliance—it’s the system that will keep your house warm, safe, and comfortable for many more years to come. 

With so many options out there, the key is focusing on what truly matters: efficiency, the right size unit for your home, the fuel type, and features that fit your lifestyle and budget. Thiele is here to guide you through each of those decisions. Here’s a breakdown of what we’ll talk about:

Understand Efficiency Ratings 

AFUE stands for Annual Fuel Utilization Efficiency. It’s the percentage of fuel your furnace actually turns into heat. Older systems might only run at 65–70% energy efficiency, which means a third of your heating dollars literally go up the flue. A new furnace—whether it’s a gas furnace, an electric furnace, or an oil furnace—can reach 95% or higher. That difference shows up as lower utility bills, less wasted energy, and a warmer, more comfortable home all winter.

Make Sure the Furnace Fits Your Home

The right furnace size matters just as much as the brand. Many homes have units that were never sized correctly to begin with, or no longer fit after an addition or remodel. A furnace that’s too small runs constantly but never keeps up, while one that’s too large cycles on and off, creating uneven temps and wearing out faster. At Thiele, we measure your home’s square footage, insulation, and layout so your new furnace is sized right for the way you live today.

Compare Brands and Warranties

Not all furnaces are built the same. Some brands are known for lasting decades, while others may not stand up as well. Warranties can also vary widely—from just a few years of parts coverage to more comprehensive plans that include labor for a decade or longer. While we’re knowledgeable about all furnace models, we’re proud to be a Bryant Authorized Dealer, which means we install high-quality furnaces backed by some of the strongest warranties in the industry.

Look at the Latest Features

Today’s furnaces can do a lot more than just switch on and off. Features like variable-speed blowers keep rooms evenly heated without sudden blasts of air. Two-stage or modulating burners allow the furnace to run at lower speeds most of the time, saving energy while maintaining steady warmth. Many models can also pair with smart thermostats, giving you more control over comfort and energy use from your phone. We’ll help you decide which features are worth investing in for your household.

Consider Your Fuel Type

Most homeowners replace their furnace with the same type they already have—and for good reason. If your home is set up for gas, a new gas furnace is almost always the best option. The fuel line, venting, and ductwork are already in place. If you’re planning a remodel or major home upgrade, that’s the time to think about switching. Some homeowners with oil furnaces choose to convert to gas when updating their home, since natural gas is widely available and usually more affordable to run. Others add electric units in new additions or outbuildings where extending gas lines isn’t practical.

Thiele has all the furnace services you need—from repairs to maintenance and replacement. But we’re more than that. As a full-service heating and air conditioning company in Indianapolis, we make sure your home stays at the right temperature all year long.

When to Replace Your Old Furnace

On the fence between a furnace repair and a furnace replacement? We get it. No one wants to replace a system if a repair can safely buy you more time. But there’s a point where putting more money into an old furnace isn’t the best solution. Here’s how to determine when replacement makes sense:

Repairs Are Adding Up

If it’s an expensive repair, is it worth it? A good rule of thumb is the $5,000 rule: take the age of your furnace and multiply it by the cost of the repair. If the number is higher than $5,000, replacement is usually the smarter move. For example, a $1,000 repair on a 16-year-old furnace comes out to $16,000—money better spent on a new system.

Rising Energy Costs

As furnaces age, they lose efficiency. A unit that started at 80% AFUE may now be running closer to 65%, meaning 35 cents of every heating dollar is wasted. If your bills keep climbing each winter despite no change in usage, upgrading to a new high-efficiency furnace can lower monthly costs and ease the strain on your budget long-term.

Uneven Heat Around the House

Older furnaces often struggle to push warm air evenly, especially if ductwork has leaks or the system is simply wearing down. If you’re constantly dealing with one room that’s freezing and another that’s too warm, that imbalance is often a sign the furnace is past its prime. A properly sized furnace replacement can restore comfort across the whole house.

Noises or Odors You Can’t Ignore

Clunks, bangs, squeals, or rattles usually mean failing internal components. Persistent odors—whether musty, metallic, or fuel-related—can point to combustion issues or worn parts that affect safety as well as comfort. While some of these problems can be repaired, frequent issues often mean the furnace is nearing the end of its lifespan.

At Thiele Heating & Air Conditioning, our HVAC technicians help Indianapolis homeowners weigh both sides. We’ll inspect your system, explain whether a repair or replacement is the better solution, and give you the information you need to feel confident in your decision. Sometimes a repair makes sense. But if your old furnace is costing more in energy and service than it’s worth, we’ll help you move forward with a reliable replacement you can count on.

The Many Benefits of Replacing Your Furnace

Replacing an old furnace isn’t just about getting heat back—it’s about upgrading the way your whole home feels. A new unit runs more efficiently, keeps every room comfortable, and takes the stress out of wondering if your system will last all winter long. The benefits start right away and continue for years to come.

• Better HVAC System Performance: A new furnace doesn’t just heat better—it helps your whole system work more smoothly. By reducing the strain on ductwork and thermostats, a properly installed unit improves airflow and efficiency across your heating and cooling equipment.
• More Consistent Comfort: Cold spots in the living room or upstairs bedrooms are frustrating. Modern furnaces are designed to deliver even, steady heat, so every corner of your house stays comfortable.
• Improved Indoor Air Quality: Older furnaces can circulate more dust, allergens, or combustion byproducts as they wear out. A properly sealed and efficient new furnace works with your filtration system to keep the air in your home cleaner and healthier. We also install indoor air quality products that can help!
• Quieter Operation: Older furnaces often rattle, hum, or roar to life. Newer models use advanced technology to run quietly in the background, so you get warmth without the noise.
• Fewer Repairs: An old furnace can nickel-and-dime you with one service call after another. A new system means fewer breakdowns, less money spent on emergency services, and more peace of mind.
• Higher Home Value: An energy-efficient furnace is a selling point for buyers who want lower bills and a reliable system. Replacing your old furnace now can add to your home’s value later.

It’s a great solution for Indianapolis area homeowners who want lower energy bills without sacrificing reliable heat in the middle of winter.
