Winter still has a ways to go and if you are having trouble with your furnace it might be time to purchase a new one. There are several options available when purchasing a new furnace. In this BLOG I will be discussing the differences between single stage, two stage and variable capacity furnaces. A single stage furnace is a furnace that runs at full capacity the entire time that the system is running. The system has a gas valve that opens to 100 percent for the entire run time. For example, if the system is an 80,000 BTU system, it will run at 80,000 BTU rate for the entire duration. A two stage furnace is a furnace that can run at full capacity or less while the system is running. The system has a gas valve that can open to 100 percent or change to about 70 percent during run time. For example with this type of system, if the system is a 100,000 BTU system, it can either run at a 70,000 BTU rate or a 100,000 BTU rate depending on the temperature. A variable capacity furnace is a furnace that can run at full capacity or less while the system is running. The system has a gas valve that can regulate the capacity between 40 percent and 100 percent. For example with this type of system, if the system is a 100,000 BTU system, it can run anywhere between a 40,000 BTU rate and a 100,000 BTU rate depending on the temperature. The more stages your system supports can create better air filtration and make for a better balanced temperature throughout the structure. The better filtration occurs because the furnace runs longer when not performing at full capacity which makes the air flow through the filter more times and removes more of the dust and allergens. If you are considering a new furnace below is a list of other advantages of using a multi stage furnace.

  • Increased Efficiency
  • Quieter Operation
  • Less System Cycling
  • More Even Temperatures
  • Improved Air Quality
