Furnace Blower Speed For Heat

I know the furnace is a goodman but need to get some specs on the blower because i know the ac coil is not the original and was replaced along with the compressor in 2012.

Furnace blower speed for heat.

The faster the motor runs the more electrical energy it spends. What is the recommended speed for your blower. How to set furnace blower speeds step 1. Most of these are on the bottom left of the control board.

Then switch the jumper to your desired speed. This n ew technology has an ecm motor with a speed controller. Carefully disconnect the wires from the coolant terminal which is located on the back of the unit. Most standard models with one heat exchanger deliver around 80 afue efficiency.

Thus if you increase the speed of the motor to deal with a drop in temperature in the house reduce the speed as soon as the house reaches a comfortable feeling in order to conserve energy. I t is more like a continuous blowing approach it provides the precise heat or cooling output your home needs at any given time day or night. The air quality is improved in your home with a variable speed blower. Connect the black wire to the manometer.

Variable speed blower motor s. Usually there will be three speeds ranging from 40 to 100 of airflow. For peak performance most ac manufacturers suggest that 400 cubic feet per minute cfm per ton of air conditioning should be used meaning that 800 cfm should be moving through the evaporator coil for a 2 ton system and so on. The manometer tells.

To be honest i prefer the slower speed of the heat side and wonder what if any impact there would be to lowering the cooling side to match that setting if it s even. Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90 or better afue efficiency. Turn off the power source that is connected to the furnace blower. On most control boards there will be a jumper that is marked to show that it controls the speed.
