Hidden Air Handlers: An Essential Component in Commercial HVAC Systems

In commercial HVAC systems, one crucial element often goes unnoticed – the air handler. These hidden components are pivotal in maintaining indoor comfort, air quality, and energy efficiency within commercial buildings. In this article, we'll delve into the world of concealed air handlers and explore their vital significance in commercial applications. 

We'll also introduce a product, the BA-HVAC-HDI Drywall Inlay - Hidden Air Handler Access Door, designed to provide a practical solution for accessing concealed air handlers. Let's begin by addressing some fundamental questions about air handlers.

What is an Air Handler?

An air handler uses the HVAC system's heating and cooling unit to distribute conditioned air throughout a building. Typically installed in well-ventilated areas devoid of excess humidity or condensation, air handlers ensure that the circulated air maintains the desired temperature and quality.

What Components Make Up an Air Handler?

An air handler comprises three primary components:

Air Filter: Nestled between the fan and intake ducting, the air handler's air filter is the first defense against contaminants. It enhances indoor air quality while safeguarding the HVAC system.

Blower Fan: The fan circulates conditioned air throughout the building, ensuring consistent temperatures and comfort in various spaces.

Evaporator Coils: Among the core components, evaporator coils are pivotal. These coils contain low-pressure, low-temperature refrigerant gas, and as air passes over them, excess heat is absorbed by the refrigerant, initiating the cooling process.

Is a Furnace the Same as an Air Handler?

An air handler and a furnace are essential components of an HVAC system, but each serves a unique purpose. The furnace uses electricity or burns fuel to generate heat while an air handler distributes conditioned air throughout the building. In some instances, an air handler and a furnace may work together to provide heating and cooling functionalities.

Do All HVAC Systems Have an Air Handler?

Most HVAC configurations incorporate an air handler, particularly in commercial environments. The air handler's role in maintaining indoor comfort and air quality is paramount. It operates seamlessly alongside air conditioners and heat pumps, ensuring efficient temperature control and circulation.

What's the Difference Between an Air Conditioner and an Air Handler?

The air conditioner, situated outdoors, is responsible for cooling the refrigerant, while the air handler, an indoor unit, circulates the conditioned air. These units are interconnected through refrigerant lines, with the air handler facilitating the cooling process.

What Impact Does an Air Handler Have on HVAC Systems?

Air handlers wield a significant influence over the performance of HVAC systems. They ensure the entire system operates efficiently with lower energy consumption when adequately maintained. When issues arise, common problems include:

Faulty Blower Motor: A malfunctioning motor can hinder proper air circulation and increase power consumption.

Dirty Evaporator Coils: Accumulated debris on evaporator coils can impede heat exchange, affecting the cooling process.

Clogged Filters: When filters are dirty, airflow is disrupted, making the HVAC system work harder and consume more energy.

When Should I Replace My Air Handler?

Like any mechanical component, air handlers have a limited lifespan. Older units may not perform as efficiently as newer ones and lack advanced technology. It is advisable to consider replacing your air handler if it is old, beyond repair, or if you are upgrading your HVAC system. When opting for an upgrade, replacing the air handler and the HVAC system concurrently ensures compatibility and maximizes efficiency.

What is a Concealed Duct Air Handler?

In commercial applications, aesthetics, and space optimization are paramount. Concealed or hidden air handlers offer an elegant solution that combines functionality with a clean and discreet appearance. These systems provide all the benefits of a multi-zone mini split without visible air handlers on walls and ceilings. Concealed duct systems are ideal for maintaining a sleek interior while enjoying efficient climate control.
