Indianapolis, IN Heating Repair

Most homes rely on a furnace—whether it’s gas, oil, or electric. A gas furnace burns natural gas, an oil furnace uses heating oil stored in a tank, and an electric furnace runs off heating elements. All of them push warm air through ducts to keep your house comfortable. Over time, parts wear out. Gas models can have ignition problems or cracked heat exchangers. Oil furnaces can gum up with clogs. Electric models often fail when a heating coil burns out.

Common furnace repairs we handle include:

• Relighting or repairing a broken ignition system
• Swapping out blower motors that stop pushing air
• Clearing clogged filters or cleaning burners that keep the flame from burning right

You may need a furnace repair in Indianapolis if the system clicks on but no air comes out, the air is cold even though the thermostat is set to heat, or you hear banging, rattling, or grinding noises. If the furnace smells like gas or exhaust, shut it down and call right away—that can be dangerous.

Boilers heat water and send it through radiators, baseboards, or in-floor pipes. They’re common in older homes and provide steady warmth, but when they go bad, you notice. A small leak around the unit can quickly turn into water on the floor. Mineral buildup inside the tank can make it rumble like a tea kettle. If the pump quits, some rooms will go completely cold even though the boiler is running.

Typical boiler repairs include:

• Tightening or replacing leaky valves and pipes
• Fixing circulation pumps so water flows again
• Clearing out trapped air or flushing mineral buildup that blocks heat

You probably need a boiler repair in Indianapolis if your radiators stay cold, you’re refilling the system too often, or you hear constant banging or hissing. A boiler that leaks water or loses pressure shouldn’t wait—it can damage your home and leave you without heat.

A heat pump works like an air conditioner that can run in reverse, and some homes use ductless mini splits for the same purpose. These systems move heat instead of making it, which means they run almost year-round. Common problems include frozen outdoor coils in the winter, low refrigerant that keeps the system from heating, or a bad reversing valve that traps the unit in cooling mode. With ductless mini splits, filters clog easily and fan motors can burn out.

Repairs we often make on heat pumps include:

• Finding and fixing refrigerant leaks
• Thawing or repairing coils that freeze over
• Replacing faulty sensors, fan motors, or reversing valves

If your heat pump is running non-stop but the house still feels cold, or it’s blowing lukewarm air no matter what mode it’s in, you likely need to schedule your heat pump repair in Indianapolis with us. Other red flags are ice building up on the outdoor unit or sudden spikes in your electric bill.

Geothermal systems use long loops buried underground to pull heat from the earth into your home. Inside, a pump moves fluid through the loops, and a heat exchanger transfers it into warm air or water. These systems are efficient but not maintenance-free. Loops can leak, pumps can wear out, and the controls can fail just like any other system. When something breaks, the symptoms are often higher bills, uneven heating, or the indoor unit making noises it never made before.

Geothermal repairs we perform include:

• Sealing leaks or blockages in the underground loops
• Replacing circulation pumps that stop moving fluid
• Repairing or recalibrating the thermostat and control systems

You may need a geothermal repair in Indianapolis if parts of your home feel colder than others, the system runs constantly without keeping up, or your energy bills suddenly climb. Since these systems are complex, it’s important to have them checked quickly so a small issue doesn’t turn into a big underground repair.
