“Don’t Get Burned!” (All About Your Furnace Burner)


During the month of love, there is a flame that keeps you going, despite the cold world out there. What is it? It’s your furnace burner!

Unless you’re particularly HVAC savvy, you probably don’t think much about your furnace burner flame.

But it’s important to take a look at it every year, in addition to your regularly scheduled maintenance, just to make sure that you keep the fire in the relationship…Uh, we mean, in order to keep your HVAC system running more efficiently.

You can take a look at your furnace’s burner flame to get a good idea of the health of your furnace. You really can judge a book by its cover!

So what should the flame look like?

It should be a full blue flame that burns straight up and is very sturdy!

Any “wavering” from this indicates that your furnace is not combusting as efficiently as it could be, which could lead to worse problems.

We’re going to get a little scientific and go back to your high school chem class to explain why blue is better:

Basically, not only is blue flame hotter than yellow, but a blue flame color indicates that the gas in the furnace is actually being combusted properly. Whether it’s propane, methane, or ethane, burning with a blue flame indicates that it’s combusting.

A yellow flame, on the other hand, means that combustion isn’t able to happen because there is not enough oxygen getting to the flame for the combustion reaction to take place. While that’s not dangerous, it is super inefficient!

That’s a long list, isn’t it?

We know you love your furnace, but it’s asking for just a little too much of a commitment from you during the month of love, huh? Plus, it’s dangerous: you’re literally playing with fire here!
