Furnace Combustion Analysis Explained

HVAC technicians do much more than simply repair furnaces that have ceased to operate. They also help to ensure that a working furnace is operating at peak efficiency. One way they are able to do this is through so-called combustion analysis. If you would like to learn more about this exciting furnace maintenance technique, read on. This article will discuss why it is in your benefit to have your furnace’s combustion analyzed. 

The Basics

Up until recently, there was no easy way to determine how efficiently your furnace’s burner was operating. Combustion analysis is a relatively new technique that allows a technician to measure how thoroughly combustion is occurring. It is an indirect method, meaning that it derives its results from measuring the presence and/or quantities of certain chemicals in the exhaust gas passing out into your furnace flue. 

Technology

In order to measure the amounts of these substances, a two-part tool called a combustion analyzer is used. One part of the tool--the probe--is placed inside of your flue while the furnace is off. This probe is designed to measure the amounts of various combustion by-products. It then sends this information to the analyzer, a hand-held tool which the HVAC technician is able to view in real-time.

Benefits

There are a number of red flags that a technician is looking for during combustion analysis. Elevated levels of substances such as sulfur monoxide and carbon monoxide are two of the most common. Both of these indicate that the combustion taking place in your furnace is far from complete. With this knowledge, the technician can make subtle adjustments to the air-fuel ratio to help ensure that more thorough combustion occurs.
