Problem: Why does my furnace and air conditioner have poor airflow?
Answer: A dirty filter, dirty blower wheel, stopped up evaporator coil, and a dragging motor (might have a weak capacitor) can cause poor airflow 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 capacitor testers on the following pages: Please click here to see the Supco Capacitor Tester we sell and Please click here to see the Ames Pocket-Sized Capacitor Tester we sell for only $32.00. Make sure your system is fully charged with refrigerant. A system that is low on charge will cause a freeze-up condition and block airflow 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 two really good YouTube videos made by fixmyownac that shows how to clean an air conditioner evaporator coil and by AC Service Tech that explains 20 causes of low airflow in heating and air conditioning systems. Thanks so very much to fixmyownac.com and AC Service Tech for making these informative videos.
