“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.

2Be sure the furnace’s circuit breaker is on or that its fuse has not blown. Check both the main electrical panel and any secondary subpanels that supply power to the unit. If the circuit has blown or tripped, reset the circuit breaker by flipping it all the way off and then on again. Or replace the fuse. If the circuit blows again, there is probably a short in the electrical system providing power to the furnace. For this, you may need to call an electrical contractor.

If you have an older furnace with a standing pilot light, it’s possible that the pilot light has been extinguished. First, confirm that the light is out. Then, turn the gas valve to the off position and wait five minutes. If there is a reset button on your furnace, turn the valve to the pilot position and hold a flame to the dedicated pilot opening while pushing the button for about 30 seconds. (If the pilot doesn’t light on the first attempt, wait a few minutes and repeat the procedure, this time depressing the reset button for 45-60 seconds.) Once the pilot is lit, turn the gas valve back to the on position. If the pilot light won’t stay lit, it’s possible that there is an issue with the thermocouple or ignition system. Call an HVAC professional for assistance.

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 is 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.
