The ABC’s of Heating – Variable Speed Furnace

Posted on: August 16, 2016

One of the most important advances in home heating and cooling over the last decade is the wider use of variable speed blower technology.

“Variable speed” simply refers to the operation of the blower motor, which operates at varying speeds to more precisely control the flow of conditioned air throughout the home.
Traditional central heating and cooling systems operated at one or two speeds.

Variable speed systems offer several advantages.

1. Improved Comfort and Air Quality

Regulated airflow provides improved control of temperature, humidity, and air distribution throughout the home. By allowing for continual airflow even when the system is not heating or cooling, air can be circulated and cleaned more effectively.

2. Quieter Operation

When a single stage furnace turns on, you’ll know it! There is a burst or air that blows out of heat registers at full force. A variable speed motor comes on gradually and operates very quietly.

3. Better Efficiency

Variable speed motors consume about 75 watts of energy per hour, while a conventional blower will consume around 400 watts per hour. This adds up to significant savings over the course of a year.

Have questions about upgrading to a variable speed furnace? Give ABC a call, we can help.
