Furnace Blower Speed For Heat

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.

Furnace blower speed for heat.

All furnaces include a heat exchanger which converts combustion gases into heat for your home. Turn off the power source that is connected to the furnace blower. The faster the motor runs the more electrical energy it spends. Carefully disconnect the wires from the coolant terminal which is located on the back of the unit.

Then switch the jumper to your desired speed. Usually there will be three speeds ranging from 40 to 100 of airflow. Increasing the furnace blower motor speed will reduce its ability to conserve energy. Most standard models with one heat exchanger deliver around 80 afue efficiency.

The air quality is improved in your home with a variable speed blower. How to set furnace blower speeds step 1. On most control boards there will be a jumper that is marked to show that it controls the speed. The manometer tells.

Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90 or better afue efficiency. Variable speed blower motor s. 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. A variable speed furnace blower motor is a step above a multi speed blower.

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. What is the recommended speed for your blower. 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. Connect the black wire to the manometer.
