Understanding the Role of Air Handlers in Your AC System


In the world of HVAC (Heating, Ventilation, and Air Conditioning) systems, understanding the components that keep your home comfortable is essential. One such crucial component is the air handler. This article will delve into what an air handler is, its role in your AC system, and why it’s vital for maintaining a comfortable and energy-efficient home.

Understanding the Basics: What is an Air Handler?

An air handler is a device that circulates conditioned air throughout your home. It works in conjunction with your air conditioner or heat pump to distribute cool or heated air via the ductwork. Typically located inside the house, often in the attic, basement, or a dedicated closet, an air handler is more than just a fan; it contains several key components that contribute to heating, cooling, and air circulation. By understanding the basics of air handlers, you can better appreciate their importance in your HVAC system.

Key Components of an Air Handler

To comprehend how an air handler functions, it’s essential to know its main components:


At the core of the air handler is the blower or fan, responsible for circulating air throughout your home. It draws unconditioned air from various parts of your house, pushes it through the system for conditioning, and then forces the treated air back into your home via the ductwork. Modern air handlers often feature variable speed blowers that adjust airflow according to specific heating or cooling needs, enhancing comfort and energy efficiency.

Evaporator Coil

The evaporator coil plays a crucial role in cooling mode. Refrigerant flows through this coil, and as warm air from your home is blown over it, the refrigerant absorbs the heat, cooling the air before it’s recirculated back into your home. This process also dehumidifies the air, improving indoor air quality and comfort.

Heating Elements

In heating mode, the air handler uses electric heating elements or heat strips to warm the air. These elements function similarly to those in an electric oven, heating up as electricity passes through them. The blower then circulates air over these hot elements, warming it before distribution. Not all air handlers include heating elements; this depends on whether your HVAC system uses the air handler for heating or if you have a separate furnace.

Air Filter

Before air is conditioned, it passes through an air filter that removes dust, pollen, and other contaminants. This improves indoor air quality and prevents particles from accumulating on the evaporator coil or other system parts, which could reduce efficiency and lifespan. Regular replacement or cleaning of air filters is crucial for maintaining efficiency.


Dampers in the air handler control airflow within the ductwork. These adjustable plates help balance the distribution of conditioned air to different areas of your home, ensuring comfort and efficiency.

How Does an Air Handler Work?

Whether your HVAC system is heating, cooling, or circulating air, the air handler plays a crucial role. Here’s a step-by-step look at its operation:

  1. Intake: The blower draws unconditioned air from your home through return ducts. This air may be warm, cool, humid, or full of particulates, depending on your home’s conditions.
  2. Filtration: The unconditioned air first passes through the air filter, trapping dust, pollen, and other airborne particles, ensuring cleaner air passes through the system.
  3. Conditioning: After filtration, the air reaches the evaporator coil or heating elements. In cooling mode, the refrigerant in the evaporator coil absorbs heat from the air. In heating mode, air is warmed by the electric heating elements.
  4. Distribution: The conditioned air is distributed back into your home through the ductwork. Dampers ensure the air is balanced and sent to the right areas of the house.

This cycle repeats multiple times per hour, maintaining the desired temperature and humidity levels in your home.

Different Types of Air Handlers

Air handlers come in various types, each designed to meet specific needs:

Residential Air Handlers

Maximizing Air Quality and Minimizing Allergies with Your HVAC System


As the warmer months roll in, so do the challenges for individuals suffering from seasonal allergies. The presence of pollen, dust, and other airborne allergens can transform a delightful summer into a relentless battle against sneezing, coughing, and itching. Interestingly, the very device that keeps our homes cool and comfortable—air conditioning—plays a pivotal role in this seasonal saga. While it’s commonly perceived as a mere source of relief from the heat, air conditioning can either be a sanctuary for allergy sufferers or a catalyst for their symptoms. This article aims to unravel the complex relationship between air conditioning and allergies, offering insights and strategies to harness your HVAC system for better indoor air quality and allergy management.

 Understanding Air Conditioning Allergies

The term “Air Conditioning Allergies” might sound like an allergic reaction to the air conditioner itself, but it’s actually a reference to allergies triggered by allergens that the AC unit circulates within your home. Symptoms can range from sneezing, runny nose, and watery eyes to more severe reactions like difficulty breathing or asthma attacks. The culprits? Pollen, pet dander, dust mites, and mold spores—all of which can find their way into your home and be distributed by an improperly maintained AC system.

How Air Conditioners Can Help Combat Allergies

Far from being the villain, air conditioners can play a heroic role in the fight against allergies. By maintaining good indoor air quality through air filtration and humidity control, air conditioners can significantly reduce the presence of allergens. Air filters, akin to the immune system of your HVAC, capture and remove these unwanted guests from your indoor air. Moreover, by keeping humidity levels in check, air conditioners prevent the growth of mold and mildew—common triggers for many allergy sufferers.

  1. Selecting the Right Air Conditioner for Allergy Sufferers

While the quest for the “best air conditioner” for allergy sufferers might seem daunting, the truth lies not in the brand or type of unit but in its maintenance and filtration capabilities. Whole-home systems, with their superior air circulation and filtration, often outperform portable or window units. However, the key to allergen-free air is regular maintenance and the quality of your air filter. Opting for HVAC systems that accommodate HEPA filters or similarly high-efficiency filters can make a world of difference in air quality.

  1. Essential Maintenance Tips for Optimal Indoor Air Quality

To maximize the benefits of your air conditioning system, consider the following maintenance tips:

  • Replace Air Filters Regularly: Dirty filters are ineffective at trapping allergens. Check your filters monthly, especially during high-allergy seasons, and replace them as needed to maintain optimal air quality.
  • Routine HVAC Maintenance: Beyond the filters, your entire HVAC system requires regular check-ups. This includes cleaning air ducts, coils, and ensuring all parts are in good working order to prevent the circulation of allergens.
  • Install an Air Purification System: For an extra layer of protection, consider integrating a UV light air purification system. These systems can further reduce airborne allergens and improve overall indoor air quality.
  • Clean Your Condenser Coil: The external part of your AC, the condenser, plays a crucial role in filtering out dust and debris. Regular cleaning ensures efficient operation and better air quality.
  1. Advanced Strategies for Allergy Relief

For those particularly sensitive to outdoor allergens, upgrading your air filter to one with a higher MERV rating can significantly improve your living environment. Additionally, don’t overlook the ductwork and vents of your home; these areas can harbor allergens and should be cleaned regularly to prevent their spread into your indoor space.


Navigating the summer months without exacerbating allergy symptoms is a delicate balance, one that a clean and well-maintained air conditioning system can help you achieve. By understanding how your HVAC system interacts with allergens and taking proactive steps to enhance its filtration and maintenance, you can create a healthier, more comfortable home environment for allergy sufferers.

If you’re ready to take control of your indoor air quality and make your home a refuge from allergies, consider reaching out for professional HVAC maintenance and air quality assessments. With the right care and expertise, you can optimize your air conditioning system to better serve the health and comfort of your household.
