To cool your home, air conditioners use a chemical known as a refrigerant to transfer heat to the outside air. To perform this function, an air conditioning system has three main mechanical components.
In size and appearance, a heat pump looks like a central air conditioner. But unlike a central air conditioning system, which only cools a home, a heat pump provides heating and cooling.
Boilers in a home generate hot water or steam for hydronic heating systems such as radiators, finned-tube baseboard heaters, radiant floor heating, radiant panels (towel warmers), kick space heaters and indirect water heaters.
Unlike conventional air conditioning systems
that use a system of ducts to deliver conditioned air throughout your
home, ductless systems use a wall or ceiling-mounted blower to deliver
cool air to a room.
