Poor airflow in your home is one of the most common complaints about HVAC systems, and the major signs of poor airflow are easy to spot.

Rooms That Stay Stuffy or Cool Unevenly

Unless a room’s supply vent has been shut off by a renovator, poor air flow is usually caused by restricted ducts or a clogged return vent.

Weak Air Coming From Individual Vents

Place your hand near an operating vent. Healthy air-flow will feel firm and continue to flow freely. Weak air-flow indicates poor airflow possibly caused by a clogged filter, collapsed duct section or overworked fan causing restricted airflow.

Doors Moving or Gaps That Whistle

Air distribution affects cooling efficiency, often as much as the actual rating of the unit. Pressure imbalances can even cause internal doors to open and create a faint whispering sound through the gaps in the windows.

The System Runs Constantly

A system that never seems to reach the desired temperature and then continues to run could be working against poor airflow somewhere in the system. Check if the filters have been replaced recently. If not, then likely there is duct leakage.

Dust Around Vent Covers

Heavy dust buildup on vent covers can indicate that air is passing through large gaps in the register instead of freely flowing through the vent cover. Cleaning the vent cover can often solve this problem, and inspecting the connection to the duct work behind the vent cover for any leakage can also be beneficial.

Seasonal Hot or Cold Spots

Changes in hot or cold areas throughout the year typically reveal an issue with duct insulation as opposed to an issue with the equipment itself. In a very humid summer and very cold winter climate such areas become very noticeable very quickly. For HVAC Williamsport PA, visit qualityairmechanical.com/hvac/.
