DIY Furnace Inspection


At Beco Air & Heat, we understand that 2021 hasn't been the kindest year for many in regard to finances. If you are having to forgo or postpone an annual heating tune-up this year, we do ask that if you have a gas furnace, you take the time to do a visual inspection for safety reasons.

Many people may not be aware that a furnace can cause a house fire if the conditions allow it. As the weather starts to get colder, many people turn on their furnaces for the first time in months and expect them to work without any prior attention at all. A furnace is a complex piece of equipment, and it needs regular maintenance to work correctly. A heating system that is maintained annually will have better efficiency, and lower heating bills. There are also safety concerns that need to be understood and addressed to reduce the chances of a furnace fire.

Inspect the Air Filter

Every home furnace will contain an air filter, which is vital for the heating system to work correctly. The air filter makes sure that the air coming into the home is free from a variety of unwanted materials, such as dirt, dust, pollen and pet hair. By removing these materials, the air filter is preventing them from causing damage to internal components in the furnace. Over time, the air filter can become blocked and clogged. When the air filter is blocked the airflow will become compromised, and the furnace will be forced to work harder to draw fresh air into the heating system. Eventually, the furnace could work so hard that it could overheat and the blower motor could even catch fire. For this reason, it’s a good idea to change the air filter on a regular basis. Best practice is to replace standard filters monthly.

Look at The Flame

The flame color indicates whether or not your furnace is burning its fuel safely and efficiently. The color and behavior of the flames can be a good indicator of the health of your heating system.

Flickering flames and incorrect flame colors (anything other than blue) are indications that your furnace is leaking energy and carbon monoxide. A healthy natural gas furnace flame is characterized by a roaring blue flame with a light blue triangle in its center. There may be a tiny tip of yellow.

A blue flame indicates safe and efficient combustion, meaning that the gas is being burned efficiently and not being wasted.

If your flame is yellow or orange, or if you see pops of yellow or orange, that is a sign that you have a combustion problem that should be addressed by a professional. If your furnace burner flames are any other color than blue, turn your furnace off and contact a licensed HVAC contractor for service right away!

NEVER attempt to fix a furnace flame’s color on your own.
