Purchasing a Furnace for your Heating System in Portland, OR

Lennox Furnace

Furnaces play a vital role when it comes to the heating system in your home. In the United States the most commonly type of furnace that can be found is a natural gas furnace. However there are others that some prefer which include an electric furnace, propane furnace, and a oil furnace. Furnaces are made up of three major parts, those are the burner, blower and the controls & safety devices.

Guidelines for Purchasing a Furnace
When purchasing a new furnace, there are three main features that will affect both price and performance: efficiency, the gas valve, and the blower motor. Normally, furnaces that have a higher performance will also have a higher price. Here at Miller’s Heating & Air we ensure that you are getting the best deal in town as well as the most trusted and reliable products.


  • Efficiency is a big factor that separates low-end furnaces from high-end furnaces. Efficiency varies anywhere from 80% to 98%. When purchasing a new heating system keep in mind that higher efficiency furnaces will usually cost more than lower efficiency furnaces. However, higher efficiency also means lower energy bills and ultimately more savings.
  • Gas valves are another main feature you’ll find in every furnace. The gas valve is the component that releases the gas to the furnace igniter. The gas valve determines the amount of gas that will be burned and ultimately the amount of heat that will be generated throughout your home. That been said there are 3 major types of gas valves you need to be aware of.
    • Modulating gas valves: These allow for precision, comfort and ultimate performance
    • Two- Stage valves: Guarantee to give you intermediate levels of performance.
    • Single-Stage valves: Economy friendly model that can create a wide range of temperature changes.
  • Blower Motors the blower motor is what moves the air throughout the home. There are three main kinds of blower motors. There is the Variable motor, ECM motor and the Direct drive. All three have different characteristics.
    • Variable speed: Energy efficient, high performance and top of the line blower motor
    • ECM motor: Power saver technology, middle line blower motor, mid- level performance
    • Direct drive: Standard blower motor, not energy efficient and its at the lower end of performance
