Air Handler vs AC Unit: A Comprehensive Comparison

An air handler and an AC unit are often used interchangeably, but they serve different purposes in a heating and cooling system.

An air handler is essentially a box that contains the heating and cooling coils, while an AC unit is a self-contained unit that includes both the cooling coils and a fan.

The main difference between the two is that an air handler is usually installed indoors, often in a basement or utility closet, whereas an AC unit is typically installed outdoors.

In terms of function, an air handler can be used with various types of heating and cooling systems, including heat pumps, furnaces, and boilers.

An air handler is a unit that controls how air moves through your home, usually located indoors and connected to both your heating and AC systems. It moves hot or cold air around as necessary.

The air handler is often confused with the air conditioner, but it's actually a separate component that can be part of both heating and cooling systems. It's responsible for circulating air throughout your home or business.

The air handler consists of a blower, heating or cooling elements, filter racks, and dampers. It's designed to effectively move air through the ducts of your home, ensuring consistent temperatures in all rooms.

Here are the key components of an air handler:

The air handler doesn't cool or heat the air, it just moves it around. If your heating system already has a blower, you might not need an air handler as well.

The air handler and AC unit are often confused with each other, but they serve different purposes. The main difference lies in their purposes, with the air conditioner solely for cooling and the air handler used to circulate air as part of the HVAC system's heating and cooling processes.

An air handler is designed to move air around, while an air conditioner exists only to cool air by removing heat from the outdoor air. They make use of air handlers to take in air, move it over evaporator coils, and then move it to the indoor area.

Air conditioners are part of a split system that includes an outdoor unit and an indoor unit, whereas air handlers are generally located indoors and may integrate with both the furnace and the air conditioning system.

Here are the key differences between air handlers and AC units at a glance:

In Fairfax, the air conditioner will predominantly be used during hot months, while the air handler runs throughout the year, pushing warm air during the winter and cool air during the summer.

An air handler is a crucial component in your home's HVAC system. It circulates air through your home, usually found indoors in a closet or attic.

The basic components of an air handler include the air filter, blower, and coil. The internal blower moves air through the evaporator coil and carries it throughout the building through the ductwork.

The air filter is located within the air handler, and its purpose is to remove contaminants from the air while the indoor coil maintains the air at a specified temperature. This is essential for maintaining indoor air quality and comfort.

Some air handlers are paired with heat pump systems, allowing both heating and cooling to be distributed through one unit.

Here are the key components of an air handler:

These components work together to provide efficient air circulation and temperature control in your home.

Replacing and maintaining your air handler is crucial for a comfortable and energy-efficient home. It's usually located inside and consists of a blower, heating or cooling elements, filter racks, and dampers.

The air handler circulates and regulates the indoor air as part of both the heating and cooling system. It's responsible for moving air through the ducts of your home, ensuring consistent temperatures in all rooms.

Replacing both the air handler and the AC unit at the same time is often recommended, especially if one component fails and the other is aging. This ensures system compatibility, prevents future breakdowns, and maintains warranty eligibility.

According to the Air Conditioning, Heating, and Refrigeration Institute (AHRI), matched systems are tested and rated together for efficiency. Replacing both at once ensures optimal SEER performance.

Some key components to consider when replacing your air handler include the blower motor, evaporator coil, air filter, and electrical controls. These parts work together to circulate and regulate the indoor air.

Here are some key components to look for when inspecting your air handler:

Proper air circulation is critical for energy efficiency and consistent indoor comfort, according to ASHRAE.

Air Conditioning Units are made up of two main parts: the air handler and the condenser. The air handler is usually located indoors, like in an attic or garage, and its job is to suck in air, cool it down, and then blow it out into the ductwork.

The air handler is a rectangular-shaped unit, similar to a refrigerator, and it often has a metal pan underneath and a condensation drain pipe going outside. Some air handlers can also function as a gas furnace or electric heater.

The condenser is the part of the AC system that's always located outdoors. It blows heat from the building to the outside environment by pulling cool air quickly over its coil. This cools the gas inside the coil, which is then sent to the air handler at a near-freezing temperature.

Inside the condenser unit, you'll find a compressor at the bottom, a fan at the top, and the coil in between, surrounded by copper pipes that lead to the air handler.
