Best ERV/HRV Ventilation Installers in Gresham, OR
What to look for in ERV/HRV Ventilation Installation in Gresham
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.

Why Gresham's Damp Winters Make Indoor Air Quality Work Different
Gresham's cold, damp winters increase mold and dust-mite growth, so choosing the best indoor air quality HVAC companies in Gresham, OR matters for healthy homes. Many local homes in older neighborhoods see spikes in humidity and musty odors during November through March. Look for providers who offer moisture testing, air filtration upgrades, and mold mitigation options.
How quickly can an Indoor Air Quality pro typically respond in Gresham during wet season spikes?
- 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.
- How soon can an ERV/HRV ventilation system be commissioned to combat damp-season indoor humidity?
- Installation windows vary, but providers often schedule ERV/HRV commissioning within 2–6 weeks depending on parts and system complexity. Confirm lead time for ordering parts and required duct modifications during the initial quote.
- Do providers offer emergency service for visible mold or musty odors during wet spells?
- Many local providers advertise emergency service availability for urgent mold or odor issues. Ask prospective contractors if they offer an emergency inspection and what response window they can commit to in wet-season surges.
- How long do typical IAQ diagnostic visits take before recommending a humidifier or dehumidifier solution?
- Diagnostic visits commonly take 45–90 minutes, including moisture readings, ventilation checks, and filter inspections. Technicians should provide written findings and a recommended humidity-control plan after the visit.
