HVAC Services in Shelby County, IN

Heating and cooling problems can affect comfort throughout the home, whether the furnace struggles in winter, the AC can’t keep up in summer, or certain rooms never reach the thermostat setting. HVAC services in Shelby County, IN, cover repairs, maintenance, installations, replacements, and indoor air quality for homes in Shelbyville and the surrounding area. 

When to Schedule HVAC Service

Heating and cooling problems often develop gradually. These are some of the signs worth having evaluated:

• Airflow feels weak, cool, or inconsistent from the vents.
• Some rooms stay noticeably warmer or cooler than others.
• The equipment cycles on and off frequently or runs for long periods without reaching the thermostat setting.
• Energy bills increase without an obvious change in usage or weather.
• You notice unusual noises or smells, including banging, squealing, or a lingering burning odor.

A technician can determine whether the problem comes from the equipment, ductwork, or thermostat and explain repair or replacement options.

Heating and Cooling Services in Shelby County

Dugan Air Heating & Cooling provides heating, cooling, and indoor air quality services for homes throughout Shelby County, from repairs and seasonal maintenance to new installations and equipment replacement.

Furnace Services

We service gas and electric furnaces throughout Shelby County. Our furnace repair team diagnoses the problem before recommending a repair or replacement.

• Repair for igniters, flame sensors, blower motors, control boards, and other components.
• Routine maintenance to inspect burners, safety controls, and airflow.
• Install and replace single-stage, two-stage, and variable-speed furnaces sized to your home’s heating load.
• 24/7 emergency heating repair when the heat goes out after normal business hours.

Heat Pump Services

We repair, maintain, install, and replace heat pumps for homeowners throughout Shelby County. Repairs cover equipment that struggles to heat or cool, runs unusually long, or short-cycles, and we size new heat pumps to the home’s heating and cooling load.

For homes with natural gas, a dual-fuel setup pairs a heat pump with a gas furnace for supplemental or backup heat. Whether that makes sense depends on the existing equipment, heating load, utility costs, and comfort priorities.

Air Conditioning Services

Our cooling services cover central air conditioning from repair to replacement. When an air conditioner is aging or needs frequent repairs, we’ll explain both repair and replacement options before you decide.

• AC repair for systems that aren’t cooling properly, run constantly, short-cycle, or make unusual noises.
• Seasonal AC maintenance to inspect the equipment and catch developing concerns.
• Install and replace equipment sized to the home’s cooling load.

Ductless Mini-Splits

Ductless mini-splits provide heating and cooling without the need for a traditional duct system. They can be a good fit for additions, converted spaces, homes without ductwork, and rooms the existing system struggles to keep comfortable.

The right setup depends on the space, existing equipment, and heating and cooling needs.

Indoor Air Quality and Ductwork

Our indoor air quality services address filtration, humidity, airflow, and temperature control. These can be added on their own or alongside new heating and cooling equipment.

• Air filtration and purification equipment to help capture particles moving through the HVAC system.
• Whole-home humidifiers and dehumidifiers to help manage indoor humidity year-round.
• UV equipment for applicable HVAC systems to address microbial growth on treated components.
• Duct sealing, insulation, smart thermostats, and zoning for better airflow and temperature control.

Frequently Asked Questions About Heating and Cooling Services

How much does a new HVAC system cost in Indiana?

A new heating and cooling setup in Indiana depends on the equipment type, its size and efficiency, and how much ductwork, electrical, or venting work your home needs. Heat pumps, gas furnaces, and hybrid setups all land at different price points. The Indiana Energy Saver Program also offers heat pump rebates for qualifying households, which can lower the upfront cost.

How much is a typical HVAC service call?

An HVAC service call cost changes with timing, since nights, weekends, and holidays cost more than a weekday visit. What the technician finds during diagnosis also shapes the final repair price. Clover Club members get reduced or waived service call fees depending on their plan.

How much does a new furnace cost for a 2,000 sq ft house?

Square footage is only a starting point, because insulation, window quality, and ceiling height all change how much heat a 2,000-square-foot home needs. The furnace’s efficiency rating and stage type affect the price too. We size every furnace from a load calculation so you don’t pay for capacity your home won’t use.
