Air conditioners
My 2 zone aircondioning has 2 units outside. I noticed one fan seems to be
going faster than the other. The amount of air coming out of the slower one seems less. What effect does this have on the system? |

What effect does this have on the system? With such little information I would assume one zone is simply calling for more cooling than the other? Or the zone sizes are different, requireing differeing cooling call? Just a thought, nothing to rely on. Pop |

Possibly a botched repair, wrong replacement part. What effect does this have on the system? Wrong condenser fan: overheating fan motor, ineffective heat transfer, reduced efficiency. Many $100s of cost over the long run. Assuming these are originally identical units! |

What effect does this have on the system? Condenser fan motors can be designed to run at very different speeds with different sized fan blades and pitch angles. Both condensers may be delivering the correct amount of CFM airflow. A complete check-up by a good tech will tell you if each unit is functioning properly and efficiently. Also, have the indoor duct systems and airflow levels checked! - udarrell - Darrell -- Air Conditioning's Affordable Path to the "Human Comfort Zone Goal" http://www.udarrell.com/air-conditio...tent-heat.html http://www.udarrell.com/proper_cfm_b...syste ms.html http://www.udarrell.com/proper_cfm_btuh_duct_sizing_air_conditioning_syste ms.html |
