Low airflow can make your home uncomfortable and lead to issues like poor temperature control and high humidity. The causes of low airflow are varied but we’ve covered the most common reasons why your Mesquite, Texas, home may be experiencing airflow problems. Read on to learn more about the top three causes.

Clogged Filters

Clogged filters are one of the most common culprits behind low airflow from your HVAC. Luckily, this is also one of the easiest to fix. Your HVAC filter is great for removing dust and other contaminants from your home’s air so that you and your family can enjoy fresh, clean air.

However, debris can build up and clog your air filter. A clogged filter can’t pull air through as effectively, ultimately leading to lower airflow. Be sure to change your filter out monthly to avoid this issue!

Ductwork Issues

Ductwork issues, particularly dirty or leaky ducts, can also lead to low airflow. Dirty ducts can cause blockages, preventing air from even reaching your vents. The system may be working appropriately, but the clog is reducing the flow of air. Leaky ducts can similarly lead to low airflow: air escapes into crawl spaces or attics before it gets to the vent.

You’ll typically notice a rise in utility bills as your system works extra time to cool or heat your home to overcome the ductwork problems. Getting your air ducts professionally inspected and cleaned is the best way to address this issue.

Frozen Coils

The evaporator coils in your HVAC can freeze over, leading to poor airflow and poor efficiency. Not quite as common as the two above, this is still something homeowners deal with regularly and it’s important to know the signs. Frozen coils are caused by a variety of reasons, including refrigerant undercharge, a leak, or low airflow over the coil itself. Regardless of the reason, it’s important to get a professional involved to get to the root of the problem and prevent it from happening again.
