Fort Wayne, IN Furnace Repair

Few things feel worse than turning up the thermostat and nothing happens. It can be linked to several things: a tripped breaker, a thermostat malfunction, a blown fuse, or a failed ignition system. Sometimes, the furnace’s safety controls have shut it down because something inside isn’t operating correctly. Our team runs a complete electrical and mechanical check, tests the ignition and flame sensors, and resets or replaces what’s needed.

If your furnace is running but only blowing cold air, it means heat is not being produced or not making it to your vents. Possible causes include a dirty air filter restricting airflow, a failing blower motor, or problems with the gas supply. In some cases, the limit switch may be faulty, shutting off the burner too soon. We inspect the entire air delivery process—from combustion to airflow—to pinpoint the issue and get warm air circulating again. Left alone, this can cause the system to overheat and shorten the life of your furnace.

Unusual noises are often the first warning sign of a failing furnace. Banging could mean delayed ignition, which allows gas to build up before igniting—something that needs immediate attention. Rattling or vibrating noises can signal loose panels, failing bearings in the blower motor, or ductwork issues. Our heating repairs include tightening connections, lubricating moving parts, and replacing worn components to protect your heating system and restore safe, quiet operation.

Short cycling happens when the furnace repeatedly shuts down before reaching the set temperature. This can be caused by dirty flame sensors, clogged venting, overheating due to restricted airflow, or even an improperly sized furnace. The constant on-and-off cycle wastes energy, increases wear, and often leaves your home unevenly heated. Our technicians test the sensors, check venting and ductwork, and evaluate system size to correct the problem and help your furnace run full, efficient cycles.

When air barely comes through your vents, your heating system is under a lot of strain. The culprits can include dirty filters, blocked or leaking ductwork, or a blower motor that’s starting to fail. Weak airflow doesn’t just make rooms uncomfortable—it can cause the heat exchanger to overheat and crack, almost always leading to a replacement. We measure airflow, inspect ducts, and test the motor to restore your furnace to peak performance and make sure your house heats evenly.

Noticing a smell from your furnace can be alarming. A dusty odor at the start of the season is normal, but strong or ongoing burning smells may mean overheating, worn electrical wiring, or a cracked heat exchanger. Musty odors may signal mold in the ductwork, while metallic or sharp smells can indicate electrical issues. We carefully investigate the source, address any safety concerns, and provide heating repairs that keep both your furnace and your family safe.

Most modern furnaces have an indicator light that flashes when something’s wrong. A steady green light usually means everything is fine, but if the light is blinking red or showing a specific code, it’s your furnace’s way of signaling a problem. It could point to issues like a faulty pressure switch, dirty flame sensor, or ignition failure. Our HVAC technicians read the error codes, run a full inspection, and perform the heating repairs needed to get your system running safely again.

Modern furnaces use either a standing pilot light or electronic ignition. If the flame won’t stay lit or the igniter keeps failing, the burners won’t fire, and the furnace can’t heat your home. Causes range from dirty flame sensors to a failing ignition control board. We clean or replace the affected parts, verify proper gas flow, and test the safety controls to ensure your heating system starts reliably every time you adjust the thermostat.

Most furnaces last about 15–20 years, but repairs and maintenance play a big role in how long yours will run. Replacing worn parts like igniters or blower motors and keeping up with yearly tune-ups can add years of dependable service. Staying ahead on small fixes and regular care is the best way to make your furnace last and keep your home comfort steady.

There are a few simple things to check first. Replace the filter if it’s clogged, make sure the thermostat is set to “heat,” and confirm the breaker hasn’t tripped. If none of those solve the problem, it’s time to call Doc Dancer for a furnace repair Fort Wayne homeowners trust.

Sometimes. A light burning smell when you first turn the system on in the fall is usually just dust burning off. But if the odor is strong, keeps coming back, or smells electrical, it may be a sign of overheating or wiring trouble.

We don’t recommend attempting DIY furnace repair. Furnaces involve gas, high voltage, and safety controls that require professional skill. What seems like a small fix can quickly become dangerous or damage the system. You could even void your warranty. The safest move is to leave the job to trained HVAC technicians.
