Furnace Blower Speed For Heat

All furnaces include a heat exchanger which converts combustion gases into heat for your home.

Furnace blower speed for heat.

On most control boards there will be a jumper that is marked to show that it controls the speed. How to set furnace blower speeds step 1. 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. Then switch the jumper to your desired speed.

A variable speed furnace blower motor is a step above a multi speed blower. Carefully disconnect the wires from the coolant terminal which is located on the back of the unit. Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90 or better afue efficiency. 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.

Connect the black wire to the manometer. The air quality is improved in your home with a variable speed blower. Most standard models with one heat exchanger deliver around 80 afue efficiency. Turn off the power source that is connected to the furnace blower.

The manometer tells. 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. Usually there will be three speeds ranging from 40 to 100 of airflow. 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.

Increasing the furnace blower motor speed will reduce its ability to conserve energy. The faster the motor runs the more electrical energy it spends. This n ew technology has an ecm motor with a speed controller. What is the recommended speed for your blower.
