Best ERV/HRV Ventilation Installers in Seattle, WA

What to look for in ERV/HRV Ventilation Installation in Seattle

For fresh-air ventilation, we weight providers who choose the right device for the climate (ERV for humid markets, HRV for cold-dry) and size it to the ASHRAE 62.2 standard — over a generic 'we install fans' claim.

  • Published ERV/HRV capability. A stated energy- or heat-recovery ventilator line, ideally naming ERV-vs-HRV selection for the climate.
  • ASHRAE 62.2 sizing. Evidence the provider sizes ventilation to the 62.2 rate rather than guessing — the difference between clearing stale air and wasting energy.
  • Google rating. A strong rating floor reflects whether the install actually fixed stuffiness/odors.

Verify before you book

  • That a unit was sized to your specific home's 62.2 rate — ask for the calculation.
  • Whether ERV vs HRV was the right call for your climate — confirm the moisture-transfer choice.
  • Active state HVAC license — check TDLR (TX), ROC (AZ), DBPR (FL), or your local board.

How quickly can a Seattle Indoor Air Quality contractor respond—and what licensing matters?

Do I need an ERV or an HRV?
Both recover most of the energy from the stale air they exhaust while bringing in filtered fresh air. The difference is moisture: an ERV transfers humidity as well as heat (the right choice in humid Texas and Florida), while an HRV moves heat only (better for cold, dry winters). A tight, stuffy, or newly-sealed home is the main candidate.
How is the right ventilation size determined?
Sizing follows the ASHRAE 62.2 residential ventilation standard, which sets the fresh-air rate from the home's floor area and bedroom count. A good installer calculates that rate rather than guessing — an undersized unit won't clear stale air and an oversized one wastes energy.
Is a permit from Seattle Department of Construction and Inspections (SDCI) required for ERV or HRV installation?
Often, yes. SDCI issues permits for mechanical ventilation systems when work alters ducts or mechanical systems. Contractors should confirm permit needs with SDCI and include permit pulls in written estimates.
How to find a specialist for balanced ventilation or whole-house dehumidifier work in Seattle?
Search for providers who document humidity readings, offer balanced ventilation design, and list ERV/HRV manufacturer training. Request project portfolios from similar homes in Capitol Hill or Queen Anne and verify permit handling experience.
How do seasonal PM2.5 spikes from traffic affect filter upgrades in Ballard and Downtown?
Traffic-related PM2.5 raises demand for higher-MERV filters during wet, low-dispersion conditions. Homeowners in Ballard and Downtown often upgrade media filters or add portable cleaners during extended wet spells to reduce indoor particulates.
