Sufficient airflow is essential for your HVAC unit to provide effective heating and cooling solutions for your home.

 You can overcome low airflow with proper maintenance. Developing a plan to keep your HVAC airflow consistent and efficient will ensure that many of the more common issues don’t become a bigger problem.

Ensure Your Home Has Proper Ventilation

 Proper ventilation is a common problem. Taking care of it can dramatically improve airflow. 

  • While most homes naturally breathe due to their architecture, a lack of proper systems for mechanical ventilation generally diminishes the level of airflow. 
  • HVAC systems make homes more comfortable by ensuring the circulation of air throughout the home. 
  • Ensuring proper air distribution is essential for airflow from your A/C.
  • The use of proper ventilation techniques can effectively distribute air equally throughout the home.
  • Proper ventilation helps balance hot and cold patches, which can inhibit smooth airflow.
  • These techniques provide valuable air conditioning with not enough airflow.

Clean or Repair Your A/C Unit’s Fan Blades

Another possible reason why your air conditioning unit might not be getting enough airflow is the accumulation of dust and debris on fan blades. As this collects, the fans cannot properly circulate air, leading to reduced airflow.

Here are some ways to ensure your fan blades are working properly:

  • Vacuum Dust: Carefully clean the dust off of the blades by using the brush attachment.
  • Deep Clean if Necessary: If vacuuming doesn’t help, you can remove the blades for deeper cleaning.
  • Check For Damage: Check blades for damage to make sure they are working correctly and replace them if necessary.
  • Replace If Necessary: If the fan blades have been damaged, purchasing a replacement can help to ensure that the airflow is always being pushed through the ventilation system properly.

Understand Your Ducting System

Ensure air ducts are the proper size and fully sealed. Double-checking the seals will guarantee your air conditioning is getting enough airflow.

Air moves through spaces differently depending on size. Improperly installed ducting leads to inefficient energy transfers, which limit the capacity of your HVAC unit to provide effectual airflow to all the spaces in your home.

Consider the use of ducting throughout the home to allow for air to be conserved and used more efficiently to produce successful airflow:

  • Size: The air inside of ducts is compressed and moves at different rates throughout the home, depending on space.
  • Length: The length of time that air flows through a duct can impact the rate at which it moves through the room, causing subtle variations in airflow.
  • Shape: Moving air from one space to another causes mixtures of hot and cold air, an important part of HVAC units managing airflow effectively. 

Any of these ducting components might be the cause of air conditioning units with not enough airflow.

Make Sure You’re Using the Correct Filter

Over time, HVAC systems filter out a large assortment of impurities from the air.

The filter prevents these particles from being recirculated, making the air better to breathe. Different units use different filter types. 

Ensure installation of the correct type for better airflow:

A/C Filter

 

  • Dimensions: Look at the dimensions of the filter to make sure it is flush, limiting the amount of air that can escape around its edges.
  • Material: Filters can be made from many things, like low-rated fiberglass to high-efficiency variants. Understanding these differences will help you improve the efficiency of filtration.
  • Rating: Filters are rated based on how long they will last. Knowing this rating will help owners keep their filters up to date.

Clean Out Your Filter

These measures effectively provide efficient airflow. However, knowing which filter to buy will only help if you keep it properly cleaned.

Follow these steps to keep your filter clean:

  • Turn Off System: Make sure you turn the power off and unplug the system before performing maintenance.
  • Consider Filter Type: The type of filter will determine how you should clean it.
  • Clean The Filter Use a cloth, a brush, or a vacuum cleaner to remove dust from the filter carefully.
  • Replace The Filter: Carefully reinstall the filter, making sure to fit it snugly back into place.
  • Check Again: Check the filter once a month or so to ensure that it is working efficiently.

Check Your System For Leaks

Old or outdated systems can often become less efficient due to leaks, causing low airflow.

Here are some basic ways to check if the HVAC system has leaks:

  • Do A General Examination: Look over the unit for any obvious leaks, feeling around for cracks or other observable areas of loss.
  • Try A Detection Test: There are a variety of established detection tests for HVAC leaks, including soap, dies, and oils.
  • Hire A Professional: Consider hiring a professional to go over the unit and find any leaks. 
  • Mix Your Methods: Using any of these methods, together or separately, can help provide airflow to your HVAC system.

Do Proper Maintenance

One of the best methods for improving HVAC airflow is to ensure that your system is undergoing proper maintenance. Preventative actions ensure that the system remains intact, effectively improving airflow.

Consider these methods for maintaining your HVAC system: 

  • Check Moving Parts: Fans, ducts, and the motor are important, but other critical components should receive routine care.
  • Check For Clogs: Look through the system for proper drainage to ensure it doesn’t clog up. This is a leading cause of reduced airflow.
  • Regular Checkups: Go over your HVAC system at regular intervals to ensure it has proper airflow.
  • Invest When Necessary: If there are specific components or parts that need replacing, it is important to note that a fully functioning system will provide much more consistent airflow.

Replace an Old Unit

Older systems are often less efficient leading to higher energy loads with diminishing returns. Looking for a new A/C unit might be the best way to improve airflow.
