Furnaces use oil or gas to heat a metal exchanger, warming the air that circulates through the home. Newer models are highly efficient, burning up to 95% of the fuel. They are typically used with ductwork and can be paired with heat pumps or air conditioners for year-round comfort.

Boilers heat water using fuel (usually oil or gas), then distribute it through baseboards or radiators. They can also serve as backup heat for heat pumps via a coil in the ductwork. Boilers offer excellent zone heating but require maintenance to avoid risks like leaks or bursts.

Heat pumps provide heating in the winter and cooling in the summer through a reversing valve. They operate on electricity and require no additional fuel sources. On cold days, a backup heater coil boosts warmth when the heat pump can’t handle the temperature alone.

Geothermal systems use the ground as a heat source or sink for refrigerant, operating similarly to a traditional heat pump. These systems are more energy-efficient than regular heat pumps but should be evaluated over their life cycle to understand their environmental and economic impact.

Ductless mini-split systems are energy-efficient, easy to install, and perfect for homes without ductwork. They offer precise control over room temperatures and work similarly to traditional heat pumps, directing air directly into the room without ducting. Mitsubishi Electric mini-splits are available through Nauman Inc., an authorized contractor.

Central air conditioning systems are designed to cool homes during the summer and help reduce humidity. Unlike heat pumps, they only provide cooling because refrigerant flows in one direction. They are often paired with other heating systems to maintain year-round comfort.
