Stay warm and comfortable with a reliable oil furnace

Comfort is the purpose behind any heating system. “Temperature rise” makes the difference between feeling warm, comfortable air from the registers in your home or the feeling of cool air blowing across you when the furnace is on. It is the difference in air temperature from the point where it enters the furnace to the point where it exits. The higher the temperature rise—the warmer the air when it enters the rooms of your home. Oil furnaces have a much higher temperature rise than natural gas furnaces. A standard oil furnaces has a 70°F temperature rise, whereas most natural gas furnaces are usually in the range of 40-50°F. This is an air temperature up to 30°F warmer than the competition—providing a far superior comfort level.
