Energy saving options
Posted: October 8, 2015
Furnaces have come a long way since they first arrived in the 1930s. Homeowners now have several options from which to choose. While many older furnaces are single stage, their modern counterparts are multi speed or variable speed systems. Here’s a description of the choices out there today, so you can make an informed choice on available technology.

Single Stage

These systems are equipped with single-stage heating units that cycle on and off as they work to keep your home at a comfortable temperature. The speed of the blower motor does not vary.
The heating unit produces a consistent quantity of warm air until the desired temperature is reached and then the thermostat turns the system off. Another characteristic of these appliances is that cold air flows from the registers when the unit first comes on. Because these appliances must cycle continually, they are the least efficient heating option.


This unit has more than one setting. The furnace blower motor is usually designed to operate at a low or high speed. Some models have a larger number of settings. This process enables the furnace to operate at the level required to maintain the temperature within your home. It can produce more or less heat as required, which enables the unit to run more efficiently at a lower cost.
A thermostat equipped with intelligent technology communicates with the furnace, dictating the speed at which the motor operates. A multi-speed furnace helps to reduce drafts, temperature fluctuations, and the noise associated with air handlers.

Variable Speed

The most quiet and energy-efficient design is a variable speed furnace. These units are coupled with a computer-controlled thermostat. In order to maintain a constant temperature within your home, the blower motor can run at several different speeds, which are adjusted automatically by the thermostat.
Because it may operate continuously at a low speed, a variable speed unit provides more even heat by constantly circulating air within your home. There are no pockets of cold air inside the ductwork. As a result, you will not experience the blast of chilly air that occurs with single stage units. Because more air flows through filters, constant circulation produces cleaner air and lowers humidity. While initially more expensive to install, the energy-efficient design saves money over the lifespan of the unit.
