Fresh-Air Ventilation (ERV/HRV) in Vancouver, WA

Fresh-Air Ventilation (ERV/HRV) in Vancouver is shaped by local conditions. Damp winters: Months of rain raise indoor humidity, so bath fans, ventilation and sealed ducts help prevent condensation and mold on windows and in crawl spaces.

Most homes have gas furnaces with or without central AC, and many older homes still use electric baseboard heat. Heat pumps are now the most common choice in new construction and replacements, and ductless units are popular in older homes without ducts. For fresh-Air Ventilation (ERV/HRV), that means the contractor should start with assess and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: gorge winds and ice storms. Cold east winds from the Columbia Gorge can bring freezing rain that ices outdoor heat pumps and knocks out power, so working defrost controls and backup heat matter.

The City of Vancouver Community Development Department issues mechanical permits inside city limits, and Clark County covers unincorporated areas. Washington licenses HVAC contractors through the Department of Labor and Industries, and Clark Public Utilities has offered heat pump incentives.
