5 Common Causes of HVAC Airflow Issues

Air conditioning on a sweltering day and heating on a freezing night is the simple comforts your HVAC system brings to your home. Here in West Texas, we know how quickly the temperature outside can change. So, having controlled comfort inside is invaluable to many Lubbock natives. But what if these comforts are disrupted? What if you can’t feel the cool breeze or the warm air you’ve come to rely on from your vents? The solution to these issues lies in understanding the root causes, and Comfort Masters is here to help you decipher them. 

The airflow from your HVAC system can be compromised by various factors, leading to less than optimal heating or cooling. From dirty filters to oversized AC units, let’s walk you through the five most common causes of HVAC airflow issues.

Dirty Air Filters

Like the lungs of your HVAC system, air filters ensure clean air circulation throughout your home. When these filters are clogged with dust and other pollutants, the airflow is restricted, like drinking a thick milkshake through a narrow straw. Lubbock and the surrounding area are infamous for being dusty so that air filters can get clogged quickly.  Not only does this cause your system to work harder, but it also compromises the air quality in your home, leading to stuffy rooms and potential respiratory issues.

Obstructed Ductwork

Your HVAC system’s ductwork is like a highway that facilitates air movement. However, debris and particles can accumulate over time and obstruct this flow, causing inefficiencies and sometimes even damage to the ducts. This, in turn, can cause air to escape into unoccupied spaces, leaving you less comfortable and wasting energy.

Blocked Vents

An often overlooked aspect of airflow issues is blocked vents. When designing your home’s interior, remember to account for the positioning of your vents. Whether it’s a cabinet in front of a wall vent or a rug covering a floor vent, these blockages can significantly hinder your HVAC system’s effectiveness.

Faulty Thermostat

Sometimes, the problem is not in the ducts or vents but in the control system. A faulty thermostat can misguide your HVAC system, causing improper temperature readings and affecting airflow. A malfunctioning thermostat can lead to unexpected airflow disruptions, whether it’s a battery issue, accidental damage, or wear and tear.

Oversized AC Unit

While bigger may be better in some situations, it’s not always the case with HVAC systems. An oversized AC unit for your home can lead to inefficient cycling and inconsistent airflow. This misconception was common a couple of decades ago, leading to many West Texas homes with older HVAC systems experiencing these issues today.
