About Us

GREENWOOD FURNACE WAS
ESTABLISHED IN 1921.

When your company goes back 100 years, you are bound to have mixed messages about the history.  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 history with us. For a long tome we believed we the Greenwood legacy began in 1921, we recently learned it was actually 1918. If you love local history like we do, check out the timeline below. I am sure Walter Zainey would be proud the heritage he created is still living on today.

Founded
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.
Transition
Pat Martin purchased the company. Over the next 7 years, Greenwood Heating and Air Conditioning become the 46th fastest growing company in Washington. They moved to Kirkland to expand the high quality service that Seattle had been enjoying for years to the Eastside.
Lennox
Ms. Martin sold Greenwood Heating to Service Experts. Service Experts is a national chain of service companies with over 200 locations and controlled by Lennox International.
Puget Sound Roots
Michael Porter, a lifelong Seattle native having worked in the HVAC industry since 1985 purchased the business. In December of 2004 Greenwood came back to its Puget Sound roots of being owned by a local Seattle resident.
