“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.
To be sure of correct sizing and a proper installation, choose a reputable contractor who will take the time to calculate your heating needs according to an industry standard such as in "Manual J HVAC Residential Load Calculation" of the Air Conditioning Contractors of America. Such calculations take into account the climate and the size, design, and construction of your house. Once the furnace is installed, maintain it regularly according to the manufacturer's recommendations. Our survey helped to confirm this advice. When we asked about the most common reasons for service calls for furnaces, contractors cited human error, inadequate maintenance, for example, or improper installation, twice as often as defective equipment. Read our frequency of repair report for which brands or the most and least reliable.

Cleaning the debris that builds up on your filters will aid with the flow of air. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly.
