Thousands of homes in Chicago and the Chicago land area are going to need a furnace replaced this winter. With all of the new technology out there, it can be hard to figure out which features you need and which ones you should skip. Two-stage heating is one of the features offered on many high efficiency models that should not be overlooked because there are four key benefits to choosing a system with this feature over one that has the traditionally one-stage heating capability.
- Improved Efficiency: When a furnace is capable of 2-stage heating, it has both a high and low setting. On days that are mild but still require heat, the furnace will operate at the lower setting. The system will still be able to meet the temperature requirements for the home, but it will do so by burning less gas than your typical one-stage furnace. The furnace will only use the high setting when the temperature outside drops low enough to require the higher output. This will save on energy costs every month. One stage systems waste energy by burning at full capacity whenever they are in operation.
- Eliminates Temperature Swings: Standard one-stage furnaces often allow for a rather large temperature difference between the thermostat reading and the actual temperature in the home. A 3-5 degree difference can be very uncomfortable and force the homeowner to set the furnace at a higher temperature in order make up for the difference. With 2-stage heating, you won’t have this problem. This type of unit heats evenly and comfortably, and any temperature differences in the home will be within a one degree difference!
- Nearly Silent Operation: 2-stage furnaces begin each cycle in the low setting and work their way up to high setting when needed. This effectively eliminates the noisy blasts of hot air that are typical of one-stage units.
- Better Air Filtration: 2-stage furnaces spend about 80% of the time in the lower stage. While in lower stage, the unit will run for longer periods of time. Since air is constantly circulating through the air filter during that time, there will be better air filtration as the filter is exposed to more particles. In your typical furnace, each cycle is relatively short, and running the fan in the “on” position would be the only way to achieve the same level of air filtration. However, you may want to think twice before changing the fan setting, because a fan that constantly runs at high speed uses a lot of energy. 2-stage systems are able to achieve this level of air filtration without being wasteful with their energy consumption.
