Greenwood Furnace was established in 1921.

Monte Jostrom started the Greenwood Furnace Co. in Greenwood area of Seattle in 1921 and built a reputation for providing quality products and services. That tradition was further refined and improved upon by Pat Martin who bought the business in 1990.

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. In 1999 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.

In December of 2004 Greenwood changed hands again but this time going back to it's Puget Sound roots, being owned by a local Seattle resident.

Michael Porter, a life long Seattle native, has worked in the HVAC industry since 1985. He is committed to complete customer satisfaction and has a mission to be 'The Premier Heating and Air Conditioning Company' in the Puget Sound area. Working to become the Puget Sound heating contractor he knows we can reach this goal by providing the Highest Quality Air Conditioning and Heating energy efficient products from the Dave Lennox Signature Collection and standing behind our work 100%.
