What Does An Air Handler Do?

An air handler plays a crucial role in your HVAC system, especially in Plainfield. It’s like the heart of your heating and cooling setup. Here’s what it does:

1. Air Circulation: The air handler moves air throughout your home. It pulls in warm or cool air from the outside and pushes it through your ductwork, ensuring consistent temperatures in every room.

2. Filtration: Plainfield air handlers often contain filters that trap dust, pollen, and other particles, improving indoor air quality. Clean filters mean cleaner air for you and your family.

3. Humidity Regulation: In humid climates like Plainfield, air handlers can help control indoor humidity levels. They remove excess moisture from the air, making your home feel more comfortable.

4. Heating and Cooling: Air handlers work with your HVAC system to distribute heated or cooled air. In winter, they circulate warm air generated by the furnace or heat pump. In summer, they distribute cool air from the air conditioner or heat pump.

5. Customization: With variable-speed motors, Plainfield air handlers can adjust airflow to match your home’s heating and cooling needs precisely. This customization ensures optimal comfort and energy efficiency.


Regular maintenance is vital for keeping your air handler running smoothly. Mister Quik Home Services offers comprehensive services, including installation, repair, and maintenance, ensuring your air handler operates efficiently year-round.

Do You Need To Replace An Air Handler If You Replace An AC Unit Or Furnace?

When considering replacing your AC unit or furnace in Plainfield, you might wonder if you need to replace the air handler too. Here’s what to know:

Air Conditioning Maintenance Plainfield
  • Compatibility: In many cases, the air handler, AC unit, and furnace are part of a matched system designed to work together. Replacing just one component can disrupt this balance and affect overall efficiency and performance.


  •  Age and Condition: If your air handler is relatively new and in good condition, you may not need to replace it when upgrading your AC unit or furnace. However, if it’s older or showing signs of wear, replacing it along with the other components can ensure optimal performance and efficiency.


  • Efficiency: Newer AC units and furnaces are often more efficient than older models. Pairing them with an outdated air handler could limit their efficiency and prevent you from maximizing energy savings.


  • Warranty Coverage: Some manufacturers require all components of an HVAC system to be compatible and properly matched for warranty coverage. Failing to replace the air handler when necessary could void warranty protection on the new AC unit or furnace.


  •  System Optimization: Upgrading all components of your HVAC system at once ensures that each part works seamlessly together, optimizing performance and efficiency. This comprehensive approach can lead to better comfort, lower energy bills, and fewer repairs in the long run.


Before making a decision, it’s best to consult with an HVAC professional from Mister Quik Home Services. We can assess the condition of your air handler and provide guidance on whether it needs to be replaced along with your AC unit or furnace.

What's The Difference Between An Air Handler and Air Conditioner?

Understanding the difference between an air handler and an air conditioner can help you make informed decisions about your HVAC system in Plainfield.

1. Functionality:

  • Air Handler: An air handler is responsible for circulating conditioned air throughout your home. It works with your furnace or heat pump to distribute warm or cool air through the ductwork and into each room.
  • Air Conditioner: On the other hand, an air conditioner is specifically designed to remove heat from indoor air and transfer it outside, cooling your home in the process. It doesn’t handle air circulation or heating functions like an air handler.


  • Air Handler: Typically, an air handler consists of a blower motor, evaporator coil, filter, and housing. It integrates with your heating or cooling system to facilitate air circulation and distribution.
  • Air Conditioner: An air conditioner comprises an outdoor condenser unit and an indoor evaporator coil connected by refrigerant lines. It removes heat from indoor air, cooling it before circulating it back into your home.

3. Versatility

  • Air Handler: Air handlers are versatile and can work with different heating and cooling systems, including furnaces, heat pumps, and air conditioners. They provide flexibility in controlling indoor air quality and temperature.
  • Air Conditioner: Air conditioners are specifically designed for cooling purposes and are not equipped to handle heating functions. They are essential for maintaining comfortable indoor temperatures during hot weather but require an additional heating system for colder months.

4.Installation and Maintenance:

  • Air Handler: Installing or replacing an air handler may involve modifications to your existing HVAC system, such as ductwork adjustments. Regular maintenance is essential to ensure proper airflow and efficiency.
  • Air Conditioner: Air conditioners require regular maintenance, including cleaning the condenser coils and checking refrigerant levels, to ensure optimal performance and energy efficiency.

Understanding these differences can help you choose the right HVAC components for your Plainfield home.

What Size Air Handler Do I Need?

Choosing the right size air handler is crucial for ensuring optimal performance and energy efficiency in your Plainfield home. Here are some factors to consider when determining the appropriate size:

Square Footage

The size of your home plays a significant role in determining the size of the air handler needed. Larger homes require air handlers with higher capacity to effectively distribute conditioned air throughout all living spaces.

Insulation and Air Sealing

Consider the insulation levels and air sealing in your home. Well-insulated and tightly sealed homes may require smaller air handlers because they retain heat or cool air more efficiently, reducing the workload on the HVAC system.


The climate in Plainfield also influences the size of the air handler needed. Hotter climates may require larger air handlers to handle the increased cooling demands, while colder climates may require larger units for heating purposes.


The condition and design of your home's ductwork affect airflow and distribution of conditioned air. Properly sized ducts ensure efficient operation of the air handler and prevent issues like air leakage or restricted airflow.

Load Calculation

Performing a load calculation is essential for accurately determining the size of the air handler needed. This calculation considers factors such as the number of occupants, appliances, windows, and orientation of your home to estimate the heating and cooling load.

By considering these factors and seeking expert advice, you can ensure that your air handler is appropriately sized to provide efficient and reliable comfort for your home.


Troubleshoot Checklist:

Air Circulation :
  • Check for consistent airflow from vents throughout your home.


  • Ensure that there are no obstructions blocking the vents or return grilles.
  • Inspect the air handler’s filters for dirt, dust, or debris buildup.


  • Replace dirty filters to maintain optimal indoor air quality.
Humidity Regulation
  • Monitor indoor humidity levels using a hygrometer.


  • If humidity levels are too high, consider using a dehumidifier in conjunction with the air handler.
