HVAC in Redmond

Microsoft's campus growth pulled buyers into Redmond's Overlake and Education Hill neighborhoods throughout the 1990s and 2000s — most of those homes came equipped with gas furnaces now 15-25 years old. PSE's heat pump rebates under the Inflation Reduction Act have made the conversion math genuinely compelling in the 98052 and 98053 zips, especially for homeowners whose equipment is failing anyway. A Mitsubishi Hyper-Heat cold-climate unit, paired with properly corrected ductwork, delivers real efficiency gains without the combustion venting complications of a furnace swap.

The 98052 zip code spans a wide spread — older split-level homes near downtown Redmond from the late 1970s, mid-century ranchers tucked off Union Hill Road, and the larger colonials on Redmond Ridge and Bear Creek built between 2000 and 2010. Builder-grade ductwork in that mid-2000s housing stock was rarely balanced for individual zone loads, which is why cold second floors and short-cycling equipment are so common here. Crawlspace moisture on the older homes is a real factor too — vapor barrier condition affects how the HVAC system handles indoor humidity from October through April. ADU projects near Marymoor Park almost always call for ductless systems — tapping into existing ductwork in an occupied home means structural demo most homeowners aren't expecting.
