What are Dual-Fuel Heating Systems and why do we Recommend them for Cincinnati?

furnace system in home

Cincinnati HVAC companies often suggest homeowners use a dual-fuel system to heat their homes. A dual-fuel heating system combines a heat pump and a gas furnace (or sometimes an oil or propane furnace) into one coordinated home comfort unit.

  • The heat pump handles mild to cool weather.
  • When temperatures drop too low, the system switches to the gas furnace for stronger, more effective heat.

The beauty of this advanced system? Dual-fuel HVAC systems automatically toggles between electricity and gas, based on which is more efficient for the current outdoor temperature.

Dual fuel is a great option for Cincinnati, since our winters are generally mild, but the mercury occasionally takes a deep dive.

How dual-fuel heating works

  1. When the outdoor temperature is mild (above 35-40 degrees Fahrenheit), the system uses the heat pump (electric). Heat pumps are ultra-efficient in moderate temperatures.
  1. When the outdoor temperature drops below 35 or 40, the system switches to using your gas furnace to heat your home. Why does it make the switch? Heat pumps lose their efficiency at lower temperatures, while furnaces deliver a reliable high-heat output.

A smart thermostat or control board manages the switch seamlessly without you needing to intervene.

The benefits of a dual-fuel system

Maximum energy efficiency

The system uses the most cost-effective fuel (electricity or gas) based on outside temperature.

Lower heating costs

Heat pumps are cheaper to run in moderate cold. Gas is cheaper for deep-freeze conditions.

Comfort and performance

You get steady warmth without overworking either the heat pump or your furnace. There’s no “cold air blow” from struggling heat pumps in freezing weather.

Longer system lifespan

The heat pump and furnace share the heating workload, reducing the wear and tear on both.

Environmental friendliness

Dual fuel systems use less fossil fuels by prioritizing cleaner electric heating when possible.

Backup protection

If one system has issues (like a power outage affecting the heat pump), you still have reliable heating.

Where dual fuel make economic sense

  • In moderate climates (like the Southeast, Mid-Atlantic and Pacific Northwest) where winters are chilly but not Arctic cold, heat pumps can handle most winter days.
  • In colder pockets (like the Midwest or mountain areas), the furnace ensures no loss of comfort during deep freezes.
  • Dual duel is perfect for places where winters fluctuate (like Cincinnati), where some days are in the 50s, other days are below freezing.

How much can you save on energy?

If your electricity rates are low but winters sometimes get really cold, a dual-fuel system can save you hundreds of dollars every year compared to relying only on electric heat or only gas!

Selecting the right dual-fuel heating system for your home

Selecting the right dual fuel heating system involves considering several factors to ensure performance and energy efficiency. You will want the guidance of a trusted Cincinnati heating service repair company like Jansen Heating & Cooling.

Size and capacity:

A heat pump that is too small may struggle to heat or cool your home adequately, while one that is too large may cycle on and off frequently, wasting energy. Factors such as your home’s square footage, insulation levels and climate conditions can help an HVAC professional determine the correct heat pump size and heating capacity for your home.

Energy efficiency ratings and features:

Look for units with a high Seasonal Energy Efficiency Ratio (SEER2) and Heating Seasonal Performance Factor (HSPF2) ratings. Higher values indicate greater efficiency. Additionally, consider features like variable-speed motors and two-stage compressors, which can enhance energy savings and comfort.
