If you’re searching for heating and cooling services, you may come across confusing, sometimes contradictory information about different HVAC systems. One component that causes plenty of confusion is the air handler. Is this the same as an air conditioner? We’re here to set the record straight.
What Is an Air Handler?
An air handler is the indoor component of some kinds of HVAC systems. It [[connects|links|attaches|hooks up] 11] to a network of air ducts that circulate conditioned air throughout the building. Air handlers differ in size, type and capacity, dependent on the application.
Some people use the jargon of “air handler” and “blower” interchangeably, but this is not correct. An air handler is an entire unit containing a blower and several other components, all of which function together to condition and circulate the air.
Does an Air Conditioner Use an Air Handler?
Usually, an air conditioner [shares|uses|utilizes]109] the furnace’s blower motor, so no air handler is required. However, in climates where home heating is not something that is necessary, an air conditioner may be the only HVAC equipment present. In this instance, the indoor air handler works in conjunction with the outdoor unit, called the condenser. In this setup, the AC unit’s air handler [blows|forces|pushes]110] indoor air [across|over|along the outside of]111] the evaporator coil, which absorbs heat and collects moisture, leaving the air handler to circulate cooled, dehumidified air back inside the building via ductwork. Refrigerant lines link the air handler to the outdoor condenser, enabling the heat transfer to the outside. This will permit the air conditioning to maintain a constant, cozy indoor temperature and humidity level.
Does a Heat Pump Use an Air Handler?
This is where air handlers are most typically found. In cold climates where heat pumps are less dependable, they are sometimes installed alongside furnaces, creating what’s called a dual-fuel system. However, advancements in cold-climate heat pumps make dual-fuel systems less typical as of late. Because there is no furnace to lend its blower motor, heat pumps need a dedicated air handler to circulate conditioned air.
Heat pumps work by pulling heat from the outside air and moving it inside using the indoor coil. The air handler blows air across the coil to collect heat before circulating it all over the building. A heat pump can also be used for cooling, where it retrieves heat from the indoor air and transfers it outside, just like an air conditioner.
Does a Furnace Use an Air Handler?
No. Furnaces come with a blower motor to move conditioned air. The blower is most likely located inside the furnace. It blows air across the heat exchanger, a metal component that exchanges heat from a fuel source to the air blowing past it. The fuel source can be natural gas, propane or oil, which is ignited to produce heat. Once heated, the air spreads back through the ductwork system and inside the building.
What Are the Parts of an Air Handler?
The [main|major|basic]69] [parts|components|pieces]70] of an air handler include:
- Blower: The blower is a motor-driven fan that disperses air by way of the ductwork. It drives air across the heating or cooling elements to control the indoor temperature.
- Heating or cooling elements: Depending on the type of HVAC system you own, the air handler may include heating or cooling elements, including an evaporator coil or backup electric heat strip.
- Air filter: An HVAC air filter takes dust, dirt and other impurities from the air as it flows into the air handler to be heated or cooled. Air filter types and efficiency ratings vary according to the system requirements. Remember to replace your air filter routinely to prevent restricting airflow through the system.
- Dampers: Dampers are used to control airflow in properties with zoned heating and cooling. They can be manually or automatically powered to direct air to particular rooms as necessary to keep a comfortable temperature.
- Humidifier or dehumidifier: Some air handlers include a humidifier or dehumidifier, which controls the indoor relative humidity level. A humidifier infuses moisture into the air in the winter, while a dehumidifier gets rid of moisture in the summer.
- Control system: The control system is responsible for regulating the air handler. It sometimes will include a thermostat, humidistat or other sensors to gauge the temperature and humidity throughout the building.
