Indianapolis, IN Furnace Repair

Same-Day and Emergency Furnace Repairs When You Need Them Most

When it’s 20° outside, it only takes a couple of hours for the temperature inside your home or business to drop to unsafe levels. It’s more than just uncomfortable—it can quickly become dangerous. That’s why we don’t make you wait when your furnace stops working. Thiele offers emergency furnace repair with fast response times, even outside normal business hours. Our technicians work on every make and model and move quickly to get the heat back on.

Some furnace problems can wait, but others can’t. If your system shuts down on the coldest day of the year, if the blower won’t stop running without producing heat, or if you smell gas or burning odors, you need emergency services. Call Thiele right away for emergency furnace repairs in the Indianapolis area.

What Are the Most Common Problems With Furnaces?

Sometimes it’s obvious when your furnace is in trouble—it won’t start, or it’s blowing cold air. Other times, the signs are smaller: strange noises, uneven heating, or the system running more than usual. Furnaces have a lot of parts working together, and after running for months straight in the winter, it’s not unusual for something to go wrong.

Dirty or Clogged Air Filter

A dirty air filter is one of the simplest but most common problems. When it’s clogged with dust, your furnace has to work harder to push air through the system. That means less heat coming out of the vents, higher energy bills, and, in some cases, the system shutting itself down. Our technicians check, replace, or clean filters to restore airflow and protect the furnace.

Ignition or Pilot Light Issues

If the furnace won’t fire up or keeps cycling without producing heat, the ignition systm or pilot light may be failing. Worn ignitors, dirty burners, or bad flame sensors are all common reasons. We’ll test each part, clean where needed, and replace what’s faulty so your furnace can run safely and reliably.

Thermostat Malfunctions

When the house never seems to get as warm as it should, the thermostat is often the problem. Older thermostats can read the temperature wrong or fail to signal the furnace properly. Sometimes a repair or recalibration is all it takes. Other times, upgrading to a smart thermostat gives you better control, comfort, and energy savings.

Blower Motor Trouble

If you’re hearing rattling, squealing, or grinding sounds—or if the air feels weak at the vents—the blower motor might be wearing out. This motor is what moves heated air through your ducts, and without it, your furnace can’t do its job. Our team can inspect the motor, lubricate moving parts, and repair or replace it if needed.

Short Cycling or Constant Running

If your furnace turns off and on constantly, or seems like it never shuts off, something’s not right. It could be a clogged filter, a failing sensor, or even a system that’s not sized correctly for your home. Our furnace inspection checks all these areas so we can get the system balanced and back to normal.

General Wear Over Time

After years of heavy use, many systems develop problems like worn belts, loose wiring, or parts that simply give out. Small problems can snowball into bigger ones if they aren’t fixed, which is why seasonal tune-ups matter. Our service professionals go through each system carefully to catch issues early and keep your furnace running smoothly.

Thiele repairs all types of furnaces, including gas, electric, and oil models. If you notice any of these issues, don’t wait—contact us for your Indianapolis, IN, furnace repair.

Furnace Troubleshooting Tips You May Want to Try First

We know there’s a lot of DIY furnace repair advice online, and while most of it isn’t recommended, there are a few basic troubleshooting steps you can safely try at home. Sometimes the solution really is something simple!

• Check the Thermostat: Double-check that your thermostat is set to “heat” and the temperature is higher than the current room temperature. If your thermostat runs on batteries, this might also be a good time to replace them.
• Replace the Filter: A clogged filter can block airflow, making your furnace less effective or even causing it to shut down as a safety measure. If your filter looks dirty or hasn’t been changed in a while, swap it out for a new one.
• Inspect the Power Source: Sometimes, the issue isn’t the furnace itself but the power supply. Check that the circuit breaker hasn’t tripped and that the furnace switch is in the “on” position.
• Relight the Pilot Light: For older gas furnaces, the pilot light needs to be lit for the system to function. If it’s out, follow your manufacturer’s instructions carefully to relight it. If you smell gas, don’t attempt this—leave your home and call for emergency assistance instead.

Trying anything beyond these basic steps can put your system and your safety at risk. Modern furnaces have sensitive components that can be damaged easily, and DIY furnace repairs can void your warranty. For anything more complicated than these quick checks, it’s best to call a professional. Thiele’s experienced technicians are here to get your furnace running again without the stress or the risk. We do the furnace repair Indianapolis trusts for a reason!

Furnace Repair vs. Furnace Replacement: Which One Is Best?

When your furnace stops working the way it should, the big question is always the same: do you repair it or replace it? The truth is, the right choice depends on your system’s age, the type of problem you’re dealing with, and how much life your furnace still has left. At Thiele, our job isn’t to push you one way or the other—it’s to help you find the best possible solution for your home. That means giving you clear guidance, upfront pricing, and honest recommendations.

When Furnace Repairs Make Sense

Not every breakdown means you need a brand-new system. In many cases, we can make the necessary repairs and give the system several more years of service. Here’s when repair is usually the right move:

• Newer Furnace: If your furnace is less than 10–12 years old, most issues can be repaired without question. These systems are built to last, and fixing a part or two can keep yours heating reliably for years.
• Smaller Problems: A clogged filter, broken ignitor, faulty thermostat, or blower motor failure are examples of isolated issues. Replacing or fixing these components is typically straightforward and affordable.
• Good Track Record: If this is your first major issue, and your furnace hasn’t needed frequent service in the past, a repair is likely okay.

When Furnace Replacement Is the Better Choice

In other cases, replacing your furnace may be the smarter investment, especially if you plan to stay in this home for several more years. Here’s when a new system is often the better long-term decision:

• Older Furnaces: Once a furnace hits 15 years or more, it becomes less efficient, harder to repair, and more prone to failure. At that stage, a new furnace installation is highly recommended.
• Frequent Breakdowns: If you’re calling for repairs two or three times a season, those costs add up fast. Installing a new furnace ends the cycle of repeat service calls.
• Major Failures: Some repairs, like a cracked heat exchanger or failed blower assembly, can cost nearly as much as replacing the whole furnace. In that situation, replacement of the unit is the better investment.
• Safety Concerns: If your furnace poses safety risks—such as recurring gas leaks or carbon monoxide hazards—replacement isn’t just an option, it’s a must.

Our technicians take the time to walk you through both repair and replacement options so you can make the best choice for your situation. If you do need a furnace replacement, you can count on us to get it done quickly. We regularly run special offers on new systems and have convenient financing options to help.
