Problem: Why does my furnace and air conditioner have poor air flow?
Answer: A dirty filter, dirty blower wheel, stopped up evaporator coil, and a dragging motor (might have a weak capacitor) can cause poor air flow on your furnace or air conditioner. I would suggest that you check the filter, evaporator coil and blower wheel to make sure they are clean. Check the capacitor on the blower motor to make sure it is reading up to specs. If you do not have a capacitor tester then you might want to purchase a new capacitor to see if it is the capacitor is the problem. Some appliance parts stores will test capacitor free of charge. We sell capacitors on the following page: Please click here to see the capacitors we sell. We sell a capacitor tester on the following page: Please click here to see the Supco Capacitor Tester we sell. 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. We have a real good YouTube video made by fixmyownac that shows how to clean an air conditioner evaporator coil. Thanks to fixmyownac.com for making this informative video.
