A heat pump, as part of a central heating and cooling system, uses the outside air to both heat a home in winter and cool it in summer.


Technically, a heat pump is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a controlled space. Installation for this type of system typically consists of two parts: an indoor unit called an air handler and an outdoor unit similar to a central air conditioner, but referred to as a heat pump. A compressor circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units.


Think of a heat pump as a heat transporter constantly moving warm air from one place to another, to where its needed or not needed, depending on the season. Even in air that’s seems too cold, heat energy is present. When it’s cold outside a heat pump extracts this outside heat and transfers it inside. When it’s warm outside, it reverses directions and acts like an air conditioner, removing heat from your home.


A furnace is a part of the heating system in which the combustion of fossil fuel and transfer of heat occurs. Furnaces can be fueled by natural gas or oil.


A gas furnace is the heating component in a majority of systems in colder weather climates. It converts gas to heat. Another option is an oil furnace that uses oil as its fuel instead of natural gas. The main components to a furnace include burners and heat exchanger, blower and controls. Trane gas and oil furnaces are built to perform again and again, year after year. Beyond performance, we also provide options for energy-efficient operation. In fact, some of our furnaces operate at over 95% efficiency, which means that 95% of the fuel you pay for is actually converted into heat for your home.


A gas furnace, or forced-air heating system, reacts when the room air temperature drops below your programmed setting on the thermostat. The silicone nitride igniter lights a burner inside the combustion chamber. The heat created is then pushed into the heat exchanger, where the air is then heated. This newly heated air moves through the duct work and into the rooms of the house. The combustion gases used to create the heat are vented through a flue in the roof or wall.
