When is the last time you changed your air filters?  Not sure? Now is the time to change them.  Dirty filters can restrict the air flowing through the system, which in turn can cause inadequate air being distributed throughout your house.  In addition, each system including ductwork is designed for a certain size air filter.  If you replace filters with 4” or 5” media filters, you can impede air, causing low airflow throughout your system and house.  Having the correct filter size and changing it monthly will allow for proper airflow circulation.     


Ductwork is designed to run to specific parts of your house.  Each run is designed to deliver the right amount of airflow to the room it supplies air to.  If the ductwork has been crushed, bent, or blocked, airflow will be reduced causing rooms to stay warm.  Depending on the type of the ductwork installed, if this is found to be a cause, the ductwork may need to be replaced.

Department of Energy claims houses generally loses 20-30% of the air moving through the ductwork from the air handler to a room in the house.  This is oftentimes due to holes in ductwork, improper seals, or cracks.  Having a thorough inspection of your ductwork completed and resolving issues can help with your airflow. 


Air moves throughout ductwork in your house from the condenser and air handler.  Having the properly sized ductwork is important because it can impact your overall comfort and airflow in your house.  Oversized ducts will reduce the air velocity, reducing the amount of air flowing into the room, causing rooms to be warmer.  In comparison, undersized ducts will cause excessive pressure near the air handler, causing the air to travel to the closest rooms while leaving the rooms furthest away to be warmer.  Having the right size ductwork impacts your system and your comfort.  If you think your ductwork may be oversized or undersized it is best to have an HVAC Professional complete a thorough inspection.
