Regarding your post, Every technician performs a maintenance differently. Today's modern furnaces really don't require as much maintenance as older style systems did. For instance: Older furnaces had drive belts, pulleys and motors with oil ports.Today's blowers are direct drive no belts, no pulleys, sealed bearing motors no oiling required. All of the new modern technology cuts the maintenance time in half if not more. Today's equipment has multiple safety's in place so that in case of a failure the system will shut down. non serviceable control boards or (Brains) monitor system functions. Unlike oil systems, the maintenance on a gas system can possibly be completed in less than half the time. I'd say 20 to 30 minutes is about right unless a service issue arises. In the 30 minute time span, the doors can be removed, system components can be visually inspected, the flame can be inspected and co test can be performed for spillage and vacuum of the combustion area can be performed if needed. The air filter should be checked and the humidifier can be activated. Remember that probing into a perfectly functioning system can be detrimental to its lifespan. My advice is change you air filter, keep the area around the equipment free of dust and try not to store in close proximity to the heating plant. Be sure you have an updated quality carbon monoxide detector in your home. Regarding the crack in your heat ex-changer, If the heat ex-changer had a crack in it, the system it should have been shut down right then and there. Be aware that Carbon monoxide may be entering your living space due to that crack. Have a knowledgeable company come back and do a CO test in your home at the supply vents and use a scope to check your heat ex-changer for cracks. I hope this helps you. Bottom line, you have to trust the company that you are using. If you feel uncertain about their capabilities, then more than likely, you instinct is correct. Good Luck to you.. Happy Holidays

Richard checks for holes in the exhaust flue that could leak carbon monoxide, particularly where the pipe meets the furnace. Small holes can be patched with foil tape, but corroded flues must be replaced. He also adjusts the flue pipe's barometric damper, which moderates the chimney draw. "A big, tall chimney in an old house tends to suck too much air, compromising efficiency," he says. "Your service pro can weight the damper to lessen the draw.

Great article! I am having trouble identifying what to use for the aluminum or zinc strips to prevent organic growth and staining. How wide are the strips? Are they predrilled? I am starting to see black stains on the north facing asphalt shingles. Do you recommend treating that befor adding the metal strips? If so, 50/50 bleach and water or a commercial product?
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.
