Benefits of Variable Stage Heating
When is it Time to Change?
- Your heating or cooling system is noisy.
- Some of your rooms are too hot or too cold.
- Your home has humidity problems and/or
excessive dust.- Your equipment needs frequent repairs and your energy bills are going up.
- Your furnace or boiler is more than 15 years old.
- Your air conditioner is more than 12 years old.
If you have an older furnace, it is likely that it is a single stage furnace.
A single stage furnace is either on or off. On when there is a call for heat, off when it’s warm enough. When it’s running, it’s running at full capacity often creating more heat then the home requires. Many people experience a large temperature range from too hot to too cold.
Two-stage and variable-stage furnaces have multiple levels of heat output—higher for cold winter days and lower for milder days. The lower setting is adequate to meet household demands a majority of the time, requiring less energy and
providing more even heat distribution.
Variable-stage furnaces start in the lower stage instead of reaching full capacity all at once. That means there is no sudden blast of air that is noisy and makes you uncomfortable. When the home has reached the desired temperature, the lower speed fan remains on for awhile, to push the remaining warm air out of the ducts.
Variable-stage furnaces provide:
- More consistent comfort
- Quiet operation
- Improved air filtration
- Efficient performance
