Have you ever experienced a time wherein some parts of your home were hot while, at the same time, other areas were cold? Or, maybe you’ve encountered your air conditioning unit blowing out warm air? These are some signs that you have HVAC airflow problems. Read on to learn about what causes your units to experience these issues.

An Incorrectly-Sized HVAC Unit

Before you pick out an HVAC system, make sure that it’s the right size for your home. If not, this will produce irregular amounts of airflow. A unit that is too big will run cycles that are shorter than they need to be. This won’t be a long enough time to remove humidity from the air. On the other hand, a unit that is too small will overwork itself to try and keep the room at the appropriate temperature.

Dirt Buildup on the AC’s Fans

When there’s a buildup of dirt on your air conditioner’s fans, this will cause your HVAC system to slow down. When this happens, your AC will have a harder time pushing out air and removing heat because of the accumulated debris preventing its movement.

Leaking Ducts

Another possible reason for reduced airflow is leaking ducts. Over time, air ducts develop holes and cracks. This makes it easier for air to leak out. Other than lessening the amount of airflow at home, this will also worsen air quality. Leaking ducts suck in dirt and debris and circulate them around the air.

Blocked Vents

Sometimes, airflow issues may not be because of your HVAC systems, after all. Perhaps, there’s a piece of furniture blocking the vent, which prevents it from letting out air. Another example could be turning off your vents one day and forgetting to turn them on again. Make sure to double-check for instances like these before calling in the professionals.
