Central Heating and Cooling
Heat pumps can use air or ground geothermal heat but lose efficiency when the temperature outside is a great deal cooler or warmer than the indoor air, making them an efficient supplement for HVAC systems in some areas. Environmental engineers and other climate control professionals frequently use "HVAC-R," or heating, ventilation, air conditioning and refrigeration in place of the older HVAC because refrigeration has become so important to HVAC systems.
Traditional air conditioning units consist of a compressor and condenser that cycles the cooled refrigerant through a box called an "air handler" in the building's ventilation system, using the fan in the furnace to force cooled air through the duct work to existing vents.
A heat pump is basically a two-way air conditioner and heat pumps make more efficient air conditioners than they do heaters. Where there is no duct work because of a hydronic or electric direct-heat system , a ventilation system must either be installed or specialized systems known as "mini-duct" or "mini-split" ductless air conditioning.
These systems run small ducts that use high-pressure fans or run the refrigerant itself to an air handler with a fan in each room to be cooled. A heat vent in a forced-air system. Older systems use the heat they produce to heat water, which in turn heats the air in your home. These systems use a boiler to store and heat the water supply, which is then circulated as hot water through pipes embedded in the wall, floor, or ceiling.
When an air conditioner is turned on, electrical power is used to cool a gas in a coil to its liquid state. Warm air in your home is cooled by contact with the cooling coil, and this cooled air is channeled to the rooms of your home through ducts and out registers or -- in the case of room air conditioners -- directly from the unit itself. In the next section, we'll review the different distribution systems used for heating and cooling the home.

Furnaces use varied heat sources, including solar energy, heat pumps, electric resistance, and combustion. The evaporator coil is used to cool down the air when your thermostat is set to a lower temperature. This cold air is then funneled throughout your home. This unit is found on the outside of your home and filled with what is called refrigerant gas.
When the refrigerant is cooled, the condensing unit pumps this liquid to the evaporator coil to be transformed into gas again. These are the outlets that help distribute heated and cooled air from the duct system into the various rooms of your home. They're generally found near the ceiling with angle slats, designed to send the air downward. It's important to ensure these vents don't become blocked. These lines carry refrigerant to the condensing unit in the form of gas.
