Check Returns

@ September 15, 2010 11:28 PM in residential AC/frozen evaporator

Along the lines of checking airflow, make sure no returns have become blocked.  I ran into two situations this summer that a customer had done some remodeling and drywallers simply eliminated returns, thus straving the system for air.  I have also seen people moving couches over return grills straving the system....Also check supply side dampers make sure they are all opened.  Many units have a variable speed motor which you can rewire to increase speed/airflow.....this can fix a symptom not the problem...if airflow seems sufficient after the system defrosts ur probably looking at an under charged system.......Do you have gauges?
