The cabinet is made of thick, strong steel that is tightly sealed so that neither noise nor heat can get out. The heavy-duty filter can be easily vacuumed or washed, so you won’t have to spend money on disposable filters again.

When saving money on energy is a big part of your budget, you should look into the American Standard Freedom 90 Gas Furnaces. They are made to last for decades and use very little fuel every day. They have a very good AFUE rating of 92.

American Standard Freedom 90 Furnace Features

  • High-efficiency blower motor
    Controlled by a microcomputer and relays that are built-in. During heating cycles, the indoor fan is controlled by a fixed 45-second time delay. You can change when the blower turns off using presets, which gives you more control over how comfortable your home is.
  • Adaptive silicon nitride hot surface igniter
    Prevents overheating, which results in a highly reliable ignition system and the longest possible service life.
  • Heavy steel insulated cabinet
    Holds more heat in the furnace and assures greater durability and quieter operation. 
  • Self-diagnostic controls
    Full diagnostics make service easy. Also has a system fault analysis for turning off the gas flow quickly and an automatic ignition retry after a fault has been fixed.
  • Easy access doors
    Quarter-turn dual door latches provide quick and easy access for servicing (upflow models only).
  • Multi-port in-shot burners
    Shape the flame cone just right to get the most heat out of it while using less fuel. There is no need to change the service.
