An air handler, or air handling unit, is the indoor part of an air-conditioning or heat pump system. Air handlers work much like furnaces in that they efficiently move air throughout the home.

What is the difference between a heat pump and an air handler?

Heat pumps are used to control your comfort by transferring heat, rather than producing it, and the air handler assists in moving all that heated or cooled air.

Does heat pump include air handler?

COMPONENTS OF A HEAT PUMP

A heat pump consists of two main components: an indoor air handler and an outdoor unit similar to a central air conditioner, but referred to as a heat pump.

How does a heat pump and air handler work together?

In heating mode, the air handler works in reverse, acting as a heat pump. It draws in cool air from the home, blows it across the warm evaporator coil, and then blows the heated air throughout the home. The cooled refrigerant travels to the outdoor heat pump, which warms it up again using outdoor heat.

How do you know if you have a heat pump?

Turn on the heat and check the outside unit

Once you feel hot air coming through your vents, walk outside and see if the outdoor unit is running. You see, a heat pump is an air conditioner that can also provide heat during the winter. So if the outside unit is running and producing heat, then you have a heat pump.

How do I know what type of HVAC system I have?

The best way is to check your outside system; there is usually a label that specifies if it is a heat pump or an air conditioner. If no such designation exists, Google the model number and brand name. You can also check for horizontal brass pipes within your condensing units, which are unique to heat pumps.

How do you know if you have a heat pump or conventional system?

From your thermostat or control system, turn the “heat” ON. Once you feel the heat coming from your return vent, head outside to observe that metal cabinet. If it is operating and you don't pay a gas or propane bill, you most likely have a heat pump!

What is the purpose of an air handler?

Most often, air handlers are located in the attic, basement or a dedicated closet, and may closely resemble the shape of a gas furnace. As its name suggests, an air handler “handles” the air inside your home and delivers warm or cool indoor air throughout your entire home.

What is the difference between an air conditioner and an air handler?

Air handlers are designed to move air around. That's all that they do. They don't heat up or cool down, they move air. Air conditioners, on the other hand, exist only to cool air by removing heat from the outdoor air.

Does a heat pump pull air from outside?

The heat pump draws air through an air return located inside the house. The heat pump never draws air from outdoors. You may be wondering why the heat pump doesn't just draw the air it needs from the outside instead of from the inside.

Where is the air handler on AC unit?

What is an Air Handler? An air handler will most likely be found inside the home as part of a split-system air conditioner or heat pump. An internal blower distributes the conditioned air throughout a home, making it feel more comfortable in the process.

Can air handler outside?

It is always the case that an air handler is located inside, but it is not always the case that the stuff inside an air handler have to be inside. For example, a packaged unit combines the compressor, condenser and evaporator coils, and the fan in one big cabinet that is always installed outside.

Can you put an air handler in the attic?

If you are going to install an AC handler in the attic, it is important that you have your attic properly insulated. Without proper insulation, cool air could be lost, and excess moisture could develop.

Can a heat pump heat a whole house?

As a proven commodity, not only are heat pumps providing Mainers with an efficient way to deliver warmth to specific areas of their homes, increasingly, they are now installing heat pumps as their primary source of heating and cooling throughout the entire home.

Do heat pumps cool as well as air conditioners?

A heat pump can heat and cool, but an air conditioner cannot, which is the primary difference between the two HVAC systems. An air conditioner is typically paired with a furnace to provide heat during the cold months.

What is a residential air handler?

An air handler, or air handling unit, is the indoor part of an air-conditioning or heat pump system. Air handlers work much like furnaces in that they efficiently move air throughout the home. The main difference is that the air handlers only circulate heat when paired with a heat pump.

Is a heat pump better than a furnace?

ENERGY EFFICIENCY

Under ideal conditions, a heat pump can transfer 300 percent more energy than it consumes. In contrast, a high-efficiency gas furnace is about 95 percent efficient. Heat pumps are powered by electricity, so you can save substantially on fuel consumption.

Is there a filter in the air handler?

The air filter is typically located at the point where the return duct enters the air handler. Larger houses often have more than one HVAC system. Each system will typically have at least one air filter. Therefore, your home may have air filters located at the air handler AND in the returns.

Is an air handler necessary?

Having an air handler that can properly handle the volume of air you need delivered to your living spaces is critical to the energy efficiency of your system and home and your personal comfort. Replacing your air handler is not a good choice for a DIY job.

How do I know if my heat pump uses O or B wire?

If you have a heat pump and your thermostat doesn't have a separate wire labeled O, then the wire labeled B should be connected to the Nest thermostat's O/B connector.

What is the difference between a heat pump and a split system?

Heat pumps move heat rather than generating heat, enabling stronger energy efficiency. Heat pumps are electrically powered, therefore creating less fuel consumption than traditional split systems. Split systems allow for individual room manipulation and continual adjustment with auto heat and cool control.

How much more does a heat pump cost than an air conditioner?

Costs. A heat pump will cost you more upfront. Assuming you already have the ductwork in place, you can expect a heat pump to cost about 1.5 to 2 times the cost of whole-house AC. A big part of the cost differential is that your heat pump handles cooling and heating.

What is a heat pump system?

A heat pump is part of a heating and cooling system and is installed outside your home. ... In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home.
