Richard sets up a combustion analyzer, which calculates furnace efficiency by measuring gasses in the exhaust flue. He makes sure that the burner's air gates are adjusted for the proper ration of fuel to air. "You want the fuel that you've brought to the be burned before it goes up the chimney," Richard says. He also replaces the oil nozzle, which atomizes the fuel just before it ignites, and checks the flame color and shape at the igniter. For either oil or gas, this is a key indicator of stable and complete combustion. In a gas system, this is the time when the burner tubes should be vacuumed clean.
There’s a common misconception that you can save money by shutting the vents (supply registers) in rooms that aren’t being utilized. Resist the urge to close too many, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can lead to failed blower motors, mold or mildew in your ductwork, damage to the compressor, a cracked heat exchanger, and other problems. What Does a Furnace Tune-Up Include?

When a furnace maintenance is performed a combustion analysis should be performed to identify any problems that couldn't be found by a visual inspection. You want to know what the Carbon monoxide level your furnace is producing as well as the oxygen/CO2 levels and stack temperate. The analyzer will also give you a calculated efficiency rating with the information the analyzer receives. You should have >100ppm of Carbon monoxide output during normal operation of your gas furnace. When you have higher numbers or CO numbers increasing during operation their is a problem with the furnace the technician should then find the cause of. This is just a brief explanation I'm trying to get across to those who get their furnace maintained and to those who don't! Check to see if anyone in the company has a NCI certification for carbon monoxide/combustion analysis.

"During the winter, all the air that your family is breathing comes through this filter," says Richard. "You can't change it too often, but never let it go for more than a year." Changing the filter is something any homeowner can do easily. At the same time, Richard checks the blower belt's wear and tension. (The blower, driven by an electric motor, moves heated air from the furnace through ductwork to room vents.) A loose belt can slow the blower, compromising efficiency. If the belt deflects more than ¾ inch when pressed firmly, it can be adjusted by sliding the motor backward slightly.

High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace are the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
