“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.

In 1995 Greenwood Heating moved to Kirkland to expand that high quality of service to the Bellevue, Issaquah, Bothell, Sammamish and the rest of the Eastside. In 1999 Greenwood Heating was sold to Service Experts, a national chain of service companies.

In December of 2004 Greenwood was sold again to Michael Porter, this time going back to its Puget Sound roots… owned by a local Seattle resident. Michael Porter, a West Seattle resident and a life-long Seattle native. He is committed to complete customer satisfaction and has a mission to be ‘The Most Trusted HVAC Company in the Puget Sound area’. To become the best heating contractor in Seattle and the Eastside he knows he must be able to provide the Highest Quality and most energy efficient Air Conditioning and Heating products on the market. But there is so much more to being the best. Greenwood Heating is also your local expert when it comes to endless hot water systems, they are also your Indoor Air Quality experts with a full product line of air cleaning products.

In 2017, Greenwood Heating was happy to announce that we have expanded and opened an additional office in the Lynnwood area to better serve our North Seattle and Snohomish county clients.

Whether you are looking for gas furnace service or repair, quality installation of a furnace, heat pump or air conditioner, mini split ductless heat pumps, endless hot water from tankless water heaters, better air quality in your home or just a filter change or duct cleaning, Greenwood Heating is your best choice of Seattle heating contractors and cooling specialists.

That’s why we say… Greenwood Heating, Washington’s Oldest & Most Trusted, Since 1921…Soon to be 1918.”
