Furnace Repairs in Indianapolis, IN

When to Call a Furnace Repair Company

Ignoring furnace problems doesn’t just lead to discomfort—it can also create safety risks, increase energy bills, and cause costly repairs. Knowing when to call for professional help is crucial. Here are six signs you need our Indianapolis furnace repair services:

Your Furnace Won’t Turn On

A furnace that refuses to start is a serious issue, especially when temperatures drop. This could be caused by a malfunctioning thermostat, a blown fuse, or ignition system failure. No matter the cause, a non-working furnace means your home will quickly lose heat, putting your family’s comfort and safety at risk.

Weak or No Airflow

If the air coming from your vents feels weak—or there’s no airflow at all—it could be due to clogged filters, ductwork problems, or a failing blower motor. Weak airflow forces your furnace to work overtime, driving up energy bills and leaving parts of your home cold. Fixing this issue early helps avoid bigger problems and improves overall energy efficiency.

Strange Noises

Furnaces aren’t silent, but loud or strange noises like banging, rattling, or squealing are a red flag. These sounds might mean loose components, a damaged blower belt, or motor issues. Ignoring them could lead to larger mechanical failures that require expensive repairs—or even a new furnace installation.

Inconsistent Heating

Cold spots in some rooms and overly warm spots in others can signal trouble. This uneven heating could be caused by ductwork leaks, thermostat issues, or an aging furnace that’s losing efficiency. Not only does this make your home less comfortable, but it also wastes energy and puts more strain on your HVAC system.

Rising Energy Bills

If your heating bills are higher than usual, your furnace may be struggling to keep up. Problems like dirty filters, worn-out parts, or inefficiencies in the system can make it work harder than it should. Addressing the issue early helps reduce costs and keeps your system running smoothly.

Unpleasant Odors

Smelling something off? A burning odor when you first turn on the heat is usually harmless, as dust burns off after months of inactivity. But persistent odors—like sulfur, rotten eggs, or burning plastic—could mean electrical problems, overheating components, or even a gas leak. Don’t take chances with your indoor air quality or safety; these odors require immediate attention.

Furnace problems don’t just affect your comfort—they can impact your home’s safety, airflow, and indoor air quality. If your furnace isn’t working properly, your heating system is likely wasting energy and costing you money.

Troubleshooting Furnaces: Tips for Fixing Your Indianapolis Furnace

When your furnace isn’t working, it’s natural to feel a little panicked—especially on a cold winter day. But before you pick up the phone, there are a few simple furnace troubleshooting steps you can try to see if it’s an easy fix:

• 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.

If these steps don’t solve the issue, it’s time to bring in the professionals. Modern furnaces are complex systems, and attempting advanced repairs without the proper knowledge can lead to safety risks, warranty voids, or even more damage to your heating system.

Thiele’s HVAC contractors in Indianapolis have the expertise and tools to diagnose and fix furnace issues quickly and safely. Save yourself the stress and let us handle the heavy lifting while you sit back and enjoy a warm, comfortable home.

What’s Wrong With My Heating System? Common Issues With Furnaces

A well-maintained furnace can last 15–20 years, but as it ages—or if it hasn’t been properly maintained—problems are bound to arise. Here are some common furnace problems and the furnace repair or replacement services we would recommend:

Dirty Filters

Clogged filters restrict airflow, causing your furnace to work harder and less efficiently. Over time, this can lead to overheating and additional wear on internal components. Regularly replacing your filter can prevent these issues, but if a clogged filter has caused further damage, Thiele’s technicians will inspect the system and repair any affected parts to restore proper airflow and efficiency.

Pilot Light or Ignition Issues

If your furnace isn’t producing heat, the problem might be a faulty ignition system or a pilot light that won’t stay lit. This could be caused by a dirty burner, a damaged thermocouple, or gas supply issues. Thiele’s team will diagnose the exact cause, clean or repair the faulty component, and ensure your ignition system is functioning safely. For older furnaces with frequent ignition issues, we may recommend a replacement to improve reliability.

Cracked Heat Exchanger

A cracked heat exchanger is one of the most serious furnace problems. It not only impacts your heating system’s performance but also poses a significant safety risk due to potential carbon monoxide leaks. Thiele prioritizes your family’s safety—if a crack is found, we’ll discuss why replacing the furnace is the better long-term solution.

Blower Motor Failure

The blower motor pushes warm air through your ducts, so if it’s failing, you may notice weak airflow or no heat at all. Dust buildup, worn belts, or electrical issues are common causes. Thiele can clean and lubricate moving parts, replace belts, or repair electrical connections to get the motor running again. If the motor is beyond repair, we’ll replace it to ensure your home stays warm.

Thermostat Malfunctions

When your thermostat isn’t working properly, your furnace might not maintain consistent temperatures or fail to turn on. Calibration errors, wiring problems, or outdated thermostats are often to blame. Thiele can recalibrate or repair the thermostat, or if needed, install a new one with modern features like programmable settings for better efficiency and comfort.

Ductwork Leaks

If your furnace seems to be working but parts of your home remain cold, leaky ducts could be the issue. Cracks or gaps in ductwork let warm air escape, reducing efficiency and comfort. Thiele will inspect your duct system, seal any leaks, and ensure your home is evenly heated.

At Thiele, we’re never pushy about recommending a new furnace unless it’s the best option for your home. If a furnace repair can extend the life of your system and keep it running efficiently, that’s what we’ll do. When replacement is the better choice, we’ll guide you through your options with honest, straightforward recommendations. Whether you need a repair, maintenance, or a new furnace installation, Thiele is here to help keep your home comfortable all winter long.

Indianapolis Furnace Repair Service

Repairs are often the go-to solution for furnaces that still have life left in them. Here’s when furnace repairs in Indianapolis make the most sense:

• Age of the Furnace: If your furnace is under 10–12 years old, most problems can be resolved with repairs. Modern systems are built to last, and minor fixes can keep your furnace running efficiently.
• Isolated Issues: Problems like a malfunctioning thermostat, clogged filter, or a broken blower motor are often isolated to specific components. Repairing these parts is a cost-effective way to get your system back in working order.
• No History of Frequent Repairs: If this is the first issue you’ve had with your furnace, it’s likely worth fixing rather than replacing the entire unit. A well-maintained system with a solid track record can still provide years of reliable heat.
• Safe to Operate: If the problem isn’t causing safety concerns—like gas leaks or carbon monoxide risks—repairs can be the practical option.

With regular maintenance and timely repairs, a functioning furnace can often serve your home for years without needing a replacement. Make sure you call our Indianapolis furnace repair service at the first sign of trouble.

Indianapolis Furnace Replacement Service

Sometimes, replacing your furnace is the smarter choice, especially if your current system is on its last legs. Here’s when a replacement is the better option:

• Outdated Furnace: Furnaces over 15 years old are less efficient and prone to breakdowns. Upgrading to a modern system can save money on energy bills and improve comfort.
• Frequent Repairs: If you’re constantly scheduling HVAC repairs, those costs add up fast. Replacing your furnace eliminates the cycle of breakdowns and provides peace of mind.
• Major Component Failure: When a critical part like the heat exchanger or blower motor fails, the cost of repairs may rival the price of a new furnace. At that point, it’s worth considering a replacement.
• Energy Efficiency Concerns: Older furnaces use more fuel and electricity than today’s high-efficiency models, leading to higher energy bills. A new system can cut your costs and reduce your carbon footprint.
• Safety Risks: If your furnace has issues like a cracked heat exchanger or recurring gas leaks, replacing it ensures the safety of your home and family.

A new furnace isn’t just about reliability—it’s about creating a comfortable, energy-efficient environment for your family.

As a Bryant Authorized Dealer, we connect you with some of the most trusted, high-efficiency systems on the market, ensuring your new furnace delivers dependable performance for years to come.

HVAC Maintenance Services for More Reliable Heating and Cooling

Many times, furnace problems can be completely prevented by regular maintenance. Unfortunately, many homeowners wait until they notice problems before scheduling furnace service, causing them to spend money on more expensive repairs rather than preventative maintenance.

At Thiele, our professional HVAC maintenance services in Indianapolis help your system perform at its best. During a furnace maintenance visit, our technicians inspect critical components like the burner, heat exchanger, thermostat, and electrical connections to identify any potential issues. Cleaning built-up dust and debris from the system improves airflow and energy efficiency, while lubrication of moving parts keeps everything running smoothly. We’ll also replace or clean filters to enhance indoor air quality and test the system to ensure it’s calibrated for optimal performance.

The best time to schedule maintenance is in the fall before your furnace goes into heavy use, and again in the spring for your air conditioning system. By timing these furnace tune-ups right, you can avoid mid-season surprises and ensure reliable heating and cooling all year long.

For homeowners who want to simplify maintenance, our Annual “Rewards” Service Agreement Maintenance Plan offers unmatched convenience and value. With perks like annual tune-ups and repair discounts, you can protect your HVAC system and save money. Call us today to learn more about our heating and air conditioning maintenance program.
