The flame sensor safeguards your furnace against the unsafe burning of fuel, and a dirty flame sensor may cause your furnace to function improperly. Typically, the flame sensor comes in the form of a rod that can be found near the back of the furnace, right in the path of the burner. To clean the sensor, turn off power to the furnace at the breaker box. Then, if possible, remove the sensor from the furnace. Scrub the sensor gently to remove dust and other residues. Finally, reattach the sensor and resume power to the furnace.

“Walter Zainey started the Greenwood Furnace Co. in the Greenwood neighborhood of Seattle in 1918 and quickly built a reputation for providing quality products and services. For years we believed Greenwood began in 1921 but only recently, May of 2017, Walter’s granddaughter shared a newspaper ad from 1968 showing that Greenwood was actually founded in 1918! When your company goes back 100 years you are bound to have mixed messages about the history but we now have an accurate founding date and founder. Thank you to the Zainey family and especially Jacklyn for taking the time to share the story with us. I am sure Walter Zainey would be proud the heritage he created is still living on.
Whether you have an electric or gas furnace, you shouldn’t have to suffer when your heater is not working. At Sears Home Services, our technicians fix many of the top furnace manufacturers. The issues you may face with your furnace can vary depending on the type of heating system. If you own an electric model and it isn’t working, some of the potential causes include:

You may think that a great air conditioner is guaranteed to provide you with a great performance. But in order to get the most from your new air conditioner,  you’ll want to schedule air conditioning installation in Renton, WA with a Bob’s professional AC technician so that you’re certain the work is done correctly. That is as easy as giving us a call.


Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can wring from each therm of gas. Since efficient furnaces generate fewer emissions, environmental considerations might also influence your decision.
