Furnace Tips: Recognizing Flame Colors
Needless to say, your furnace is a very important piece of equipment, so it pays to have even a basic understanding of how it works. Keeping track of how efficiently it’s operating and knowing when to have it serviced can save you hundreds–if not thousands–of dollars in the long term. Home heating companies also highly recommend familiarizing yourself with the different flame colors your furnace may produce and learning the meaning behind each.
What Color Should Your Furnace Flame Be?
Your natural gas furnace should produce a very distinct blue flame with a lighter blue triangle at its center. There may also be a tiny bit of yellow around the tip. A roaring blue flame indicates efficient combustion, meaning the gas is being burned efficiently and very little is going to waste.
Blue flames are also hotter. If the flame your furnace produces is yellow, green or orange, or if you see little pops of these colors in the flame, then you need to seek the help of a professional. This likely means that you have a combustion problem that should be addressed by a properly- licensed HVAC company.
In addition to inefficient combustion, when the flame is a color other than blue, this could also mean higher heating bills and more soot. However, the real danger of a non-blue flame is the increased amount of carbon monoxide produced by the combustion process. Carbon monoxide has been dubbed the “silent killer”, as it’s an odorless, colorless, and tasteless gas that can cause headaches, nausea, hallucinations, blackouts and even death.

We had our AC go out on one of the hottest days of the year. We called as soon as they opened and they came out so quickly and offered us some loaner units to keep our babies and animals cool in the meantime. Matt was so helpful and fixed the problem quickly. He went above and beyond to help us and we will be using Stone Heating and Air to replace our unit when it’s time. They’ll be our first call in the future!
Matt's response was extremely quick, he was very professional and friendly. He explained everything in detail and was very knowledgeable. He had my unit up and running within no time! I highly recommend calling stone heating and air. I will be signing up for the yearly service plan with them!!
