TWO-STAGE FURNACES WHAT IS TWO-STAGE HEATING AND IS IT FOR ME? Do you sometimes find it challenging to obtain the ideal temperature within your home during the winter months? First, it's cold so you turn up the thermostat which starts the furnace; then it's so hot you turn it down again. Traditional furnaces are designed to heat your home and keep you warm during the coldest weather in your climate, therefore, they operate at one level---high. However, even during winter temperatures fluctuate and many winter days can be somewhat mild. Unlike traditional furnaces that turn on and run at full capacity with each demand for heating,two stage furnaces operate like two separate furnaces to maintain more consistent comfort in your home. The unit starts out running in it's first stage and operates at about 68% of it's heating capacity. This reduced capacity is sufficient to warm your home on mild winter days. But when the temperature outside really drops, the furnace adjusts to full capacity ( second stage )to meet the demand for heat within the home. It's kind of like having 2 furnaces for the price of one. With two stage heating you won't have to keep adjusting the thermostat. ADVANTAGES OF TWO STAGE HEATING: Consistent comfort Quiet comfort Improved air filtration Efficient operation If you want and expect high-level performance from your heating equipment, then a two stage furnace is the right choice for you.
