The oil filter (found in oil-powered systems only) prevents small impurities from clogging the oil-burner nozzle, which could result in a misfire that shuts down the system. Richard first closes the oil valve, then removes the old filter and replaces it, setting aside the dirty filter to be disposed of according to local hazardous-waste regulations.

Your furnace's flame sensor is essentially a safety mechanism. As a thin metallic rod in front of the flame inside the unit, it's sole purpose is to confirm that your gas valves only open when a flame actually exists to burn that gas. When the flame sensor stop working, on the other hand, gas leaks can occur. To repair your furnace's flame sensor, expect to spend between $80 and $250. Even a full replacement of this part typically does not go above that range.
Another energy savings tip, HVAC professionals say, is using a programmable thermostat. A programmable thermostat can save you up to 10 percent on energy bills, if you dial it down seven or eight degrees from the normal temperature setting — the U.S. Department of Energy recommends a setting of 68 degrees — for eight hours a day, whether it's during the work day or at night, according to DOE.

If you invest in a sub par heating system then you can expect nothing more than a sub par performance from your furnace. Even so, it is possible to get a lousy performance from your furnace even if it is of the highest quality. That is because your furnace installation in Kirkland, WA is just as important to the performance of your furnace as the quality of the system itself.
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?

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.
