How to Diagnose and Solve Airflow Problems

Cold spots in a home, weak airflow from vents, and a system that barely heats or cools during extreme temperatures – these are all problems that can be unbearable. Not to worry, we can help! This helpful guide will cover common causes of airflow problems and will help you diagnose and solve issues to keep your family comfortable all year long.

Common HVAC Airflow Problems

Compromised airflow can make you feel uncomfortable in your home, and the reason can be simple. To help you identify the cause, here are some of the most common signs of an airflow issue and how to fix them.

Compromised Filters

A filter is a critical component of an HVAC system. A filter that is too thick or too dirty to allow proper airflow will compromise the comfort of your home.

First, check to see if the filter is clean. If it is clean and airflow is still a problem, then check the thickness of the filter. If the filter is too thick, with a MERV (Minimum Efficiency Reporting Value) rating higher than 12, the filter may create more resistance than the system can handle and should be replaced.

Blocked Vents or Registers

A blocked vent or register can be caused by something as simple as clothes on the floor. Though it seems minor, blocked vents can cause uneven pressure and compromised airflow, which in turn creates drafts and hot or cold spots in the house.

Once you pinpoint that this is the problem, the solution is simple. Check the return vents and registers to make sure they aren’t blocked to ensure there is adequate airflow returning to the unit.

Duct Damage

The ductwork in your house is what delivers air from the HVAC system to the inside of your home. When the duct is compromised, the system can’t deliver the correct amount of air, and your comfort suffers.

Breaks, tears, or cracks in ductwork can cause air from the HVAC unit to leak. If a duct is crushed, bent, or knocked out of place, this can lead to insufficient airflow as well. Compromised ductwork can be tested and repaired relatively inexpensively by your trusted HVAC professional.

Fan or Thermostat Issues

If the thermostat is faulty or the fan isn’t working, the HVAC system may not function correctly. This a common electrical problem. Make sure the thermostat battery is working and the circuit breaker doesn’t need to be reset. Also, check the fan to make sure it is operating correctly. If not, you may need to call your HVAC professional to further investigate the issue.
