What Causes Poor Air Flow In A System?
A dirty filter, blower wheel, stopped up evaporator coil, and a dragging motor can cause poor air flow. I would have your evaporator coil and blower wheel checked to make sure they are clean. Check the capacitor on the blower motor to make sure it is reading up to par. If you do not have a capacitor tester then you would need to purchase a new capacitor to see if it is the capacitor. Make sure your system is fully charged with refrigerant. A system that is low on charge will cause a freeze up condition and block air flow through the evaporator coil. To identify which capacitor you need you would need to turn off your power and take the capacitor loose and try to read the specs on the capacitor. What could be causing my indoor coil to freeze up? Freeze ups are caused most of the time by a low refrigerant charge. Before you call someone to check the charge on your system I would make sure the filter is clean. Freeze ups can also be caused by a dirty blower wheel, dragging motor (might ne
