Seattle does not experience extreme heat or cold, but that does not mean your HVAC system has it easy. The city's long spring and fall seasons force furnaces and air conditioners to cycle on and off constantly to maintain comfort. Short-cycling puts stress on blower motors, capacitors, and contactors, which are the primary sources of HVAC noise. A system that runs for six hours straight experiences less component fatigue than one that cycles every 15 minutes. In neighborhoods like Greenwood, Ravenna, and Laurelhurst, older single-stage furnaces and air conditioners cycle aggressively because they are oversized for the mild climate. That repetitive startup stress wears out bearings and loosens mounting hardware, creating the rattling and banging sounds that drive homeowners crazy.
Peak HVAC Seattle understands the specific demands of Seattle's climate on HVAC equipment. We have worked on thousands of systems in homes throughout King County, from the houseboat communities on Lake Union to the hillside homes in West Seattle. We know that Seattle's damp air corrodes ductwork faster than in dry climates, and we know that homes built before 1980 often lack proper duct insulation, which amplifies every sound. When you call Peak HVAC Seattle, you get a technician who knows your neighborhood, your building type, and the exact components that fail most often in this region. That local expertise means faster diagnosis and better repairs.
