Furnace Repair in Shelbyville

Our expert furnace repair is available to Shelbyville locals for issues like:
- Poor airflow or no air coming from the vents.
- Uneven heating, with warm and cold spots throughout the house.
- Unusual sounds coming from the furnace, like squealing, banging, or rattling.
- High energy bills whenever the furnace is turned on.
- A weak, yellow, or split pilot light flame.

These issues indicate problems with your furnace’s internal components. It could be a simple fix, such as cleaning the air filter, or you may need more extensive repairs to the fan motor or heat exchanger.

Dugan Air Offers 24/7 Emergency Heater Repair in Shelbyville, IN

Furnace emergencies include:
- Gas leaks: If you smell gas or your carbon monoxide alarm goes off, evacuate and ensure your safety before calling for assistance.
- Fire hazards: Smoke, burning odors, unusual noises, breaker trips, or visible soot or melted wires are all serious fire hazards that must be addressed immediately.
- Heavy water leaks: If water is leaking from the furnace, especially near electrical components, this is a furnace emergency that must be handled ASAP.
- No heat in cold weather: If your heater has no power or isn’t heating your home properly when it’s cold outside, it’s more than a comfort issue. It’s a health concern, and your home is at risk of water damage from burst pipes in the walls.
If your heater is posing a risk to you, your loved ones, or your home, don’t hesitate to call Dugan Air Heating & Cooling. Our techs are available 24/7 for emergency service. We’ll arrive as quickly as possible with the tools needed to diagnose and resolve the issue.
Furnace Replacement in Shelbyville
Your furnace may need to be replaced if it’s constantly breaking down, if your energy bill skyrockets every time you turn the heat on, or if it’s unsafe. You don’t want to risk fire hazards or gas leaks in your home.
We provide easy furnace replacement to Shelbyville residents. Whether you want a simple central air furnace or a modern, programmable high-efficiency model, our qualified techs can help you find the perfect gas or electric furnace for your needs after an in-home assessment. Once we’ve found the right furnace, an installation permit from the city is required. When it’s all in place, we will schedule your installation appointment at your earliest convenience.
Financing Options & Rebates Available for New Heating Units
There’s never a good time for your furnace to break down. HVAC expenses can be frustrating, and needing heat pump installation or emergency servicing on your heater is stressful. At Dugan Air Heating & Cooling, we understand what you’re going through, which is why we offer helpful financing options. Get the HVAC tune-up, repair, or replacement you need now, and with approved credit, you can pay it off in smaller, more manageable payments that suit your budget better.
Furnace Tune-Ups & Preventive Maintenance

Tune-ups and proactive preventative furnace maintenance keep your furnace running efficiently. Without regular furnace tune-ups, you may face issues like:
- Poor efficiency and high energy bills.
- Bad air quality.
- Uneven heating.
- Wear and tear on furnace components.
- Safety issues or breakdowns.
When you schedule seasonal maintenance with Dugan Air Heating & Cooling, a knowledgeable technician will provide a full safety inspection, check your ductwork, clean, tighten, and lubricate components, and ensure the furnace is operating efficiently.
Heat Pump Options in Shelbyville
Heat pumps are a good choice for most Indiana homes, especially those designed for cold climates or used in tandem with a “dual-fuel” system with both a heat pump and a furnace. They offer heating and cooling from a single system and manage Indiana’s humid summer weather effectively, making them an energy-efficient and convenient option for whole-home comfort.
At Dugan Air Heating & Cooling, our HVAC technicians tune up and repair heat pumps to ensure they remain in excellent working order year-round. We install both air-source and geothermal heat pumps. Both types are available as traditional heat pumps or ductless models for homes without ductwork, or for areas of your house that could benefit from additional heating and cooling, such as your garage or an add-on.
Air source heat pumps
An air-source heat pump extracts heat from the air and transfers it into or out of your home, depending on your needs. This allows the heat pump to act as both a heating and cooling system. Even when it’s below freezing outside, the refrigerant inside the heat pump is cold enough to extract heat from the air and bring it indoors.
Geothermal heat pumps
A geothermal heat pump (or “ground source” heat pump) extracts heat from the earth rather than from the air in the winter to heat your home and then uses the ground as a heat sink for cooling in the hot summer months. Ground temperatures remain stable. It typically ranges from 55 to 60 degrees, making it a reliable resource for both heating and cooling.
Geothermal heat pumps are highly efficient, environmentally friendly, and provide consistent heating and cooling to your home. They are also completely housed indoors, so you won’t have a large, noisy condenser beside your house.
