A single stage furnace turns on when you need heat and turns off when the home is comfortable. Its the same system we have been using since furnaces were invented. This method has and still does work but there are much better and environmentally friendlier furnaces available..
This model of furance has two setting, Low and High, when the weather is mild out the furnace turns on at low power saving you money. When the temperature gets colder the furnace will increase to high power and keep you comfortable. It will choose the most energy effiecnet setting on its own based on the temperature outside.
A Variable Speed Furance means a smart furnace, this model can pick any level of heat it needs, from 10% Power to 100% similar to the Two Stage except it has hundreds of stages. Nothing is more efficent or more comfortable.
With new technology comes new controls, a new furnace today will need a special thermostat capable of controling its different stages of heat. We offer two models, the Honeywell T6Pro thermostat and the Lennox mulit stage thermostat. We make sure you have the right thermostat with the right furnace.
An A/C powered furnace motor will use much more electricity costing you more money and typically is much louder. A D.C Motor will use significantly less electricity and will run much quieter in some cases you won't hear it at all..
The last part to think about when your looking for a furnace is how quiet does it need to be ? Is there a bedroom above your furnace ? is there a bedroom in your basement ? Depending on your situation quiet may or may not be something important to you.
