Why does my furnace run so much?
A dirty furnace filter is the number one reason we’ve found that furnaces run constantly. The air filter captures dust, pet hair, and debris that could damage the furnace and keeps it from getting to the heat exchanger. If the filter is dirty, it restricts airflow across the heat exchanger, which causes it to overheat!
Do high efficiency furnaces run more often?
The simple answer is “yes” – but for a good reason! High efficiency furnaces run more often to save energy and reduce your utility bills. By running more consistently, the furnace can operate at an even pace throughout the day rather than working hard in spurts.

What is the difference between a blue flame and an orange flame?
Blue Flames Indicate Temperatures of 2,300 to 3,000 Degrees
Blue flames burn hotter than orange flames, with temperatures reaching up to 3,000 degrees Fahrenheit. Along with the complete burning of carbon, this is why gas-burning fires typically have a blue flame.
What causes orange flame in furnace?
If you have a yellow, orange, or red burner flame, this usually means that your burner is not receiving enough air for complete combustion. Besides wasted gas, higher energy bills, and more soot, the main danger of improper combustion is the increased amount of carbon monoxide (CO) produced by the combustion process.

Dirt in the burner is the most common cause of a yellow flame, and it prevents the gas and air from mixing properly. A call to a technician for cleaning and evaluation is needed to fix that problem.
Why is my furnace flame yellow?
Yellow flames signify the generation of carbon monoxide, an odorless, colorless, tasteless gas that can produce headaches, nausea, hallucinations and, in severe cases, blackouts, in addition to being a symptom of inefficient combustion. Yellow and orange flames provide the least amount of heat.
