What are the causes of low airflow in a home?
These reduce the level of comfort and increase heating and cooling costs. The Department of Energy tells us the typical duct system has between 35-50% leakage. This means 35 to 50% of the air meant to travel from the air handler to a certain area of the home is not making it to its intended location.
Why does my furnace have a low air flow rating?
Most residential systems can adequately remove airborne contaminants with a filter rated MERV 7 to 12. The higher the MERV rating, the smaller the pores are for air to flow through your furnace filter. Smaller pores can create more resistance in airflow than a system is designed to manage, thus making it inefficient.
What causes reduced airflow in a ductwork system?
As discussed in the article titled “The Two Primary Causes of Reduced Airflow in Ductwork” on the Energy Vanguard blog by Dr. Allison Bailes, the two main causes of reduced airflow are friction and turbulence. Below, we’ll look at a few of the most common issues that cause friction and turbulence in HVAC systems.
Why is the air coming out of my vents so weak?
Why this restricts airflow: Your air ducts deliver cool air throughout your home. So, if there are any holes, leaks or blockages within the duct system, you’ll notice a decrease in the amount of cold air coming from your vents.

Why is the airflow on my blower so bad?
If the airflow is only bad on one type of outlet (say, defrost or lower outlet), then it is likely a restriction in the blower outlet line to that particular outlet. Get the cat out of the dash!!!
