When we talk about Heating, Ventilation, and Air Conditioning (HVAC) maintenance, we often think about the air conditioning unit and the furnace. Everybody knows we must clean condenser coils regularly and watch out for gas leaks. 

It’s a no-brainer that we need to test safety switches and examine the system for any signs of corrosion or damage. However, there is much more to HVAC maintenance than just the air conditioner and furnace alone.

The air ducts are one of the most underrated parts of an HVAC system. The air ducts carry the air from the furnace or air conditioner throughout your home. It is essential to keep the air ducts clean and maintain them regularly to ensure the air quality in your home is healthy and safe. 

Unfortunately, many people often forget about their air ducts until they notice the airflow is too low. This also often comes with higher power bills, as the AC or heater unit has to work harder to maintain the same temperature. If this sounds like your situation, then you need to determine the cause of the impeded airflow. Here are four reasons why there is low airflow in your home.

1. Clogged or Dirty Air Filters

Air filters trap dirt, dust, and other particles from entering your home. However, if the filter is not replaced or cleaned regularly, these particles can build up and clog the air ducts, leading to low airflow. Additionally, clogged or dirty air filters can decrease air quality, resulting in health issues for your family, including allergies and asthma.

2. Leaky Ductwork

Leaky ductwork can cause air to escape, leading to low airflow. This can be caused by improperly sealed joints between sections of the ductwork or by holes in the ducts themselves created by rodents and other small animals that may have made your air ducts their home.

3. Blockages

There are a variety of things that can cause your air ducts to become blocked. The most common culprits are furniture, debris, and other objects in front of the vents. While this can seem trivial, it can significantly impact the airflow in your home. If a large piece of furniture blocks an air vent, it can reduce the airflow and make it more difficult for your HVAC system to keep your home at the desired temperature. 

4. Improperly Sized Ducts

If your ducts are too small for the size of your home, this can lead to low airflow. This is because the air has difficulty traveling through the small ducts and can become trapped, leading to low airflow. Unfortunately, improperly sized ducts are the handiwork of inexperienced contractors.
