Air Handler Unit

Do you wish to upgrade your HVAC system? Then you will probably need to know about the air handler unit. Depending on the season, it circulates and conditions both hot and cool air. To get the most out of your HVAC system, an air handler works in combination with your air conditioner or heat pump. As replacing a home HVAC system is such a massive investment, picking the proper brand solutions is important. That is why you should be aware of all vital details to make a wise decision and save money. In this article, we will explain how air handlers operate, which ones are ideal for your system, and how much does the air handler cost.

What Is An Air Handler?

As they appear similar and are both placed inside the house, you may confuse an air handler with a furnace. The air handler unit is the indoor element of your two-part system that collaborates with the heating and cooling equipment to provide a consistent environment throughout your
house. It contains an evaporator coil, a blower, and various ventilation system components like filter racks or chambers, sound attenuators, and dampers. It is a part of your HVAC system that works with your split-system heat pump or air conditioner on the inside.

How Does it Work?

The air handler unit has to exchange heat and spread it throughout the house. It is typically used in conjunction with your existing HVAC system. Installation is usually done in well ventilated sections of your home, or in places where there is no condensation or humidity. The external heat pump collects heat from the air outside to heat your house via its refrigerant.
On the other hand, air flows into the air handler from the return duct to chill your house. It blows over the evaporator coil within the air handler, which absorbs heat and eliminates humidity with the help of the refrigerant contained inside it. One thing you need to keep in mind, if the indoor air handler and outdoor heat pump are not properly matched, the system will not provide the expected efficiency levels, resulting in higher
energy costs.

What are Upflow and Downflow Air Handler?

Upflow Air Handler

An upflow air handler is designe for upright installation and circulates air via the side or bottom before exhausting it through the top. It is commonly found in the basement, closet, and attic installations. It draws cold air from the bottom of the unit and discharges warm air upwards. Because heat flows from the floor of a room upwards, up-flow air handlers tend to heat areas more efficiently.

Downflow Air Handler

Downflow refers to the airflow of a certain air handler. Heat is sent downwards by the downflow air handler to the place that demands it. As a result, it is naturally suit to installation in attics. If you don’t have an attic, they might be put on the top levels of your home.

How Much Does An Air Handler Cost?

To supply cooled or heated air for an indoor space, air handlers link to an air conditioner or heat pump. They are available in a range of sizes and typically last 10 to 15 years. To treat the air, they may employ refrigerant, chilled water, or hot water. A fan coil unit is a non-ductwork form
of the handler. An air handler costs between $500 and $3,500, with most households spending between $700 and $1,500. However, it may vary in size, brand, and quality.
