Furnace Repair in Carmel, IN

If your furnace won’t turn on, something in the start-up sequence isn’t doing its job. It could be the thermostat, the furnace switch, or an ignition component. You can check the thermostat batteries, make sure the switch is on, and confirm the breaker hasn’t tripped. If it still won’t turn on, we’ll go through the heating system step by step to find what’s stopping the startup so your home can stay warm again.

If the furnace is running but only pushing out cold air, the burners may be shutting off, the system may be overheating, or airflow is restricted. A clogged filter is common, so replacing it is a good first step. If the air stays cold, we’ll check the flame sensor, burners, blower motor, and airflow to restore heat throughout the home.

A furnace that never shuts off usually means it can’t reach the thermostat setting, or the blower is stuck in the “on” mode. Check that the thermostat’s fan is set to “auto.” If it still keeps running, we’ll look at airflow restrictions, thermostat communication, and internal parts to get the system cycling normally again and help keep energy costs under control.

If your furnace starts but shuts off before warming the home, something is interrupting the cycle. It might be overheating, a sensor issue, or airflow problems. You can try replacing the filter or checking the thermostat settings. If it still short cycles, we’ll examine the burners, safety controls, and airflow to help your heating system run through a full cycle and keep the home temperature steady and warm.

New, sudden noises—like banging, squealing, rattling, or scraping—mean something inside the furnace isn’t working the way it should. You can make sure the access panels are tightened, but if the noise continues, we’ll check the blower, motor, and moving parts to prevent wear and keep the furnace in top shape for the rest of the season.

A burning smell right after the first cold day can be dust burning off, but if it lingers, there may be an electrical issue or overheating component. Gas smells are different—leave the home if you notice gas. Once it’s safe, we’ll inspect the burners, wiring, and heat exchanger to make sure your furnace is running safely and maintaining good indoor air quality.

When airflow feels weak or uneven, the furnace may not be pushing air through the ducts the way it should. A clogged filter or closed vent can cause this, so those are easy things to check first. If airflow is still low, we’ll look at the blower motor, ductwork, and airflow path to restore proper circulation and keep your home comfortable with consistent comfort.

Most furnace repairs take about an hour or two, depending on what we find once we’re inside the unit. Smaller fixes can be handled quickly, while larger issues may take a little more time. We arrive prepared so you get the heating solutions you need as soon as possible.

Furnace repair costs vary depending on what’s wrong and how involved the work is. Some of the least expensive repairs are things like small electrical components or sensors that have worn out over time. On the other end, major repairs—like a blower assembly or a heat exchanger—are the most expensive and sometimes get close to half or more of the price of a new system. We’ll tell you exactly what’s going on, what your options are, and what makes the most sense for your home now and in the future.

In most cases, yes, furnaces can be repaired and still run well for years. If repair makes the most sense for the long run, that’s the direction we’ll go. If the furnace is too old or the repair cost outweighs its remaining life, we’ll talk through replacement options so you can make the call.

It depends on the age of your furnace and whether its parts still fall under the manufacturer’s warranty. Many warranties cover parts but not labor. If you’re unsure, we can help you check coverage when we’re out for your HVAC system inspection.
