Central and direct heat are the two main types of heating systems. With direct heat, a freestanding furnace is used, but doors need to be left open to allow some of the heat to circulate from the heated room to outer rooms. Central heat is provided by an HVAC system. The furnace can be placed indoors or outside, and it’s the best option for heating and cooling for businesses and residential settings.
Heating and air installation systems use both a furnace and air conditioning unit. HVAC heating is a central heating system. A blower-fan inside the system delivers warmed air to rooms through ductwork connected to air registers or grills. Another name for this type of heating system is forced-air. The furnace can run on electricity, natural gas, propane, or fuel oil. Combustion products vent to the outside through a flue pipe. A single furnace can keep an entire house at a comfortable temperature with a single thermostat on the wall. Today’s furnaces burn fuel with 90% efficiency.
The air conditioning unit uses the same ductwork as the furnace to deliver cooled air throughout the house or workplace. It is a part of the HVAC system, and the blower-fan of the furnace circulates the cooled air. Sometimes the heating unit is placed on top of the roof, and the air conditioning unit is placed on the ground. There are various placements of equipment depending on individual situations. Many businesses with flat roofs have rooftop installations for all the HVAC equipment. An HVAC heating and cooling service company can do repairs of existing equipment or install a new system. HVAC system planning is usually part of a new construction.
A furnace using a single thermostat forces the warm air to the entire house or workplace. If you have rooms that aren’t in use all day, you can save energy costs by lowering, or turning off, the zoned thermostat. Programmable thermostats can be installed by the heating and air conditioning service to automate your HVAC system to save energy, and to have the proper required temperature ready when needed.
A heat pump does both heating and cooling with the same unit. In the summer, the unit works by removing heat from the indoors to the warmer outside. In the winter, the process is reversed. The heat is taken out of the colder air via an electrical system in the unit and expelled inside the house. Heat pumps use ductwork to deliver heat throughout the house, but a smaller unit can be installed for a heat- or cool-deprived room in a house with no ductwork. There are two types of heat pumps. The air-source heat pump uses the outside air in summer and winter. A ground-source heat pump can heat and cool in any climate because it exchanges heat with the ground through a loop buried underground. The air-source heat pump is more common because it’s easier to install and less expensive. The initial cost of a heat pump system is higher than the furnace and air conditioning units, but it delivers more energy than it consumes, making it more cost-effective in the long run.
