Air Handler HVAC: Everything You Need to Know
Air handlers are the heart of your HVAC system, quietly working to keep you comfortable year-round. This comprehensive guide covers everything you need to know about air handlers, from how they work to the different types available. Understanding the role of an air handler is crucial for anyone involved in building management, whether it’s for a shopping mall, hospital, hotel, office, school, or any other type of building. This article is your key to unlocking optimal indoor comfort and efficient climate control.
What is an air handler?
An air handler is a critical component of your HVAC system. It’s the indoor unit that works tirelessly to circulate conditioned air throughout your home or building. It’s like a furnace, but instead of generating heat, it conditions and distributes the air cooled by your air conditioner or heated by your heat pump. Think of it as the lungs of your HVAC system, breathing in and out the air that keeps your indoor spaces comfortable.
As an air handling unit manufacturing plant, we design and build air handlers with ultimate flexibility to meet the diverse needs of our clients. We cater to a wide range of customers, including those seeking HVAC chillers, air conditioners, and complete HVAC systems for various building types to ensure the air in your home is conditioned effectively.
How Does an Air Handler Work? (Air Handler Work Explained)
An air handler works by circulating air throughout your home. It pulls in warm air from your home through return ducts. This warm air passes through an air filter, removing dust and other particles. Then, the air passes over the evaporator coil, where the refrigerant absorbs the heat from the air. Now cool, the blower in the air handler circulates the cooled air back into your home. In heating mode with a heat pump, the process reverses, with the larger air handler circulating heated air.
Our air conditioning system is designed to provide optimal comfort in your home. HVAC Chillers are essential for maintaining the air conditioned environment in larger buildings. Air handlers come in different designs to seamlessly integrate with air handlers, providing efficient cooling solutions for a variety of applications.
Types of Air Handlers (Type of Air Handler Breakdown)
Different Types of air handlers exist to meet the needs of various HVAC systems:
- Standard Air Handlers: These air handlers come in different sizes and are typically paired with a heat pump or air conditioner; they are the most common type found in homes and buildings.
- Fan Coil Units: These compact units are used in individual rooms or zones, providing localized temperature control.
- Makeup Air Units (MAUs): These units introduce outside air into a building to maintain proper ventilation and air quality.
- Rooftop Units (RTUs): These self-contained units are designed for outdoor use, typically on the roofs of commercial buildings. They combine the functions of an air handler and an outdoor unit (like a condenser or heat pump) to optimize air conditioning.
Notre gamme de Refroidisseurs d'eau à spirale refroidis par eau provides versatile cooling options for various air handler configurations.
Components of an Air Handler
Inside a typical air handler, you’ll find several key components:
- Ventilateur: The blower is the motor and fan that circulate the air.
- Evaporator coils (cooling) or heat strips (heating) are essential components of an air conditioning system. These components condition the air, either cooling it with refrigerant or heating it with electric heat, ensuring that the air is conditioned properly.
- Filtre à air : This removes dust, pollen, and other contaminants from the air, improving indoor air quality.
Do You Need an Air Handler? (Need an Air Handler?)
Whether you need an air handler depends on your HVAC system. If you have a central air conditioner or heat pump, you almost certainly have an air handler. They are essential for distributing conditioned air throughout your home.

When to Replace Your Air Handler (Replace Your Air Handler)
Several signs indicate it might be time to replace your air handler:
- Age: If your air handler is over 15 years old, it might be nearing the end of its lifespan.
- Frequent Repairs: Constant repairs can be costly and indicate declining performance.
- Reduced Airflow: Weak airflow can signify problems with the blower or ductwork.
- Poor Indoor Air Quality: If you notice increased dust or allergies, it might be time for a new air handler with improved filtration to help keep the air in your home clean.
- Strange Noises: Unusual sounds can indicate failing components in your air conditioning system.
Air Handler vs. Furnace: What’s the Difference?
While both circulate air, air handlers and furnaces have distinct roles. Furnaces generate heat, while air handlers condition and distribute air. They often work together in HVAC systems.
For specialized cooling needs, consider our Refroidisseurs industriels pour galvanoplastie ou notre Refroidisseurs industriels pour patinoires applications, which can be integrated with custom air handler solutions.
Air Handler vs. Air Conditioner: Understanding the Difference Between an Air Conditioner and an Air Handler (Difference Between an Air Conditioner and an Air Handler)
An air conditioner and an air handler are distinct parts of a cooling system. The air conditioning system, usually the outdoor unit, cools the refrigerant to maintain a comfortable environment. The air handler circulates the cooled air throughout your home. They work together as a team to keep you cool.
Notre Refroidisseurs au glycol can be used with air handlers in applications requiring precise temperature control, such as breweries and industrial processes.
Air Handlers and Heat Pumps
Air handlers are frequently paired with heat pumps to provide both heating and cooling. The air handler circulates the air, while the heat pump either heats or cools the refrigerant depending on the season. This combination offers energy-efficient climate control.
The Importance of the Air Filter
The air filter in your air handler plays a vital role in maintaining good indoor air quality. Regularly replacing the air filter can help to remove dust, pollen, and other airborne particles, ensuring the air circulating in your home is cleaner and healthier.
FAQ
How often should I replace my air filter to ensure that the air in your home remains clean?
It’s generally recommended to replace air filters every 1-3 months, depending on usage and air quality.
What size air handler do I need?
The correct size depends on several factors, including the size of your home and your climate. Consult with an HVAC professional for accurate sizing.
What is the average lifespan of an air handler?
Air handlers typically last 15-20 years with proper maintenance.
How can I improve the efficiency of my air handler?
Regular maintenance, including filter changes and coil cleaning, can significantly improve efficiency. Upgrade to a variable-speed blower can also boost energy savings.
What are signs that my larger air handler needs repair?
Unusual noises, reduced airflow, and inconsistent temperatures can indicate problems with your air handler.
