Greenwood, IN Heating Repair

Most Greenwood homes use a gas furnace for heat, and after years of hard winter use, it’s common for things to start wearing out. Dust on the burners or flame sensor can keep the furnace from lighting. The ignitor might stop sparking, or the blower motor may start straining to move air through dirty filters or older ductwork. Even something small—like a loose wire or weak capacitor—can cause the furnace to start and stop constantly or never warm the house the way it used to.

Common furnace repairs include:

• Replacing failed ignitors, flame sensors, or control boards
• Cleaning burners and heat exchangers so the furnace lights reliably
• Fixing or replacing blower motors and belts to restore strong airflow

You might need a furnace repair in Greenwood if the system runs but the air never gets warm, the blower keeps cycling on and off, or you hear loud banging, rattling, or screeching. Check your air filter first—if it’s clogged, swap it out. But if that doesn’t help, give us a call. A quick repair now can keep a minor problem from turning into a major one later.

A lot of older homes in Greenwood still use boilers for heat. They’re reliable systems, but they need attention now and then to keep working right. You might start to notice uneven heat, gurgling sounds in the pipes, or a little water around the tank. Those are signs of things like low pressure, air in the lines, or buildup from hard water. Over time, that buildup can slow everything down and make the boiler work harder than it should.

Common boiler repairs include:

• Replacing circulation pumps that stop moving water evenly
• Flushing out sediment or trapped air from the pipes and radiators
• Sealing small leaks and replacing worn valves or fittings

If your radiators are staying cold, the system keeps losing pressure, or you’re hearing knocking or hissing, it’s time to schedule a boiler repair in Greenwood. You can check your pressure gauge—it should sit somewhere around 12–15 psi. If it’s much lower or bouncing up and down, turn it off and give us a call.

Heat pumps do double duty in Indiana—cooling your home in summer and heating it through the winter—so they see a lot of wear. You might notice the outdoor unit freezing over, the system blowing cool air instead of warm, or it just running nonstop without making much of a difference. Usually, that means low refrigerant, a bad reversing valve, or a sensor that’s reading the temperature wrong.

Common heat pump repairs include:

• Fixing refrigerant leaks and recharging the system
• Replacing worn fan motors, sensors, or control boards
• Clearing ice buildup and checking defrost cycles

If you’ve got a ductless mini split, those can act up too—especially in basements, garages, or bonus rooms that are harder to heat. If the unit’s not responding, making odd noises, or blowing weak air, it’s time for a heat pump or ductless mini split repair in Greenwood. Try cleaning the filters first, and if that doesn’t fix it, we’ll get it sorted out quickly.

Geothermal systems are efficient and last a long time, but they still need service once in a while. They work by pulling heat from underground through a loop system, and over the years, those loops can leak or lose pressure. Inside, the pumps or flow sensors can wear down, causing your system to run constantly without really heating the house.

Common geothermal repairs include:

• Finding and sealing small leaks in underground loops
• Replacing worn pumps or sensors that affect circulation
• Cleaning and testing the indoor heat exchanger and controls

If your geothermal system has been running longer than normal or your utility bills have jumped, something’s probably off. Schedule a geothermal repair in Greenwood, and we’ll check the parts of the system to pinpoint the problem before it gets worse.
