Well a vast majority of the homes, here in Colorado. Have standard, single stage 80% natural gas furnaces. But with the extreme weather changes. A 2 stage furnace might be just the thing, to help save on utility cost. As the time changes, so does the technology. Just like our cars got a little smarter over time, so did heating equipment. Furnaces have a number of different models.
We like to offer a 2 stage, variable speed fan motor natural gas furnace. This furnace has a 2 stage gas valve. A standard single stage furnace, runs at just one single continuous heat.
2 Stage gas valve
A 2 stage furnace, has the ability to talk to the thermostat and a 2 stage gas valve. When the furnace starts up, it comes on at first stage. Only using a % of the energy needed. Saving money on running costs and also more comfortable feeling environment. Then as it communicates with the thermostat. The furnace makes a decision. If it is still early November it might just shut off on first stage. But if it gets to negative 5 outside. Your furnace will decide, its taking a longer time to satisfy the thermostat. Then kick into second stage, and get the job done.
Variable speed fan motor
Another great accessory for a natural gas furnace. Is the variable speed fan motor. This new technology changes the electrical energy of the motor, from AC to DC. This change makes the motor more efficient. This motor also utilizes variable speed technology. Allowing the motor to supply the right amount of air, at the right time. This will increase the comfort and efficiency, of your natural gas furnace.
