What to look for in ERV/HRV Ventilation Installation in West Allis

- 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.

Why West Allis, Wisconsin homeowners search for "Indoor Air Quality" fixes after harsh winters
Prolonged cold and tight, heated homes after West Allis winters trap moisture, dust, and combustion byproducts, raising allergen and mold risk. Homeowners searching for best indoor air quality HVAC companies in West Allis, WI often need ventilation upgrades and duct inspections to cut odors.
What West Allis homeowners ask about "Indoor Air Quality" repairs, timelines, and emergency response
- 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 do I find an ERV/HRV ventilation specialist in West Allis?
- Search for technicians with ventilation-specific training and references for ERV/HRV installs. Ask about duct layout plans, manufacturer-dealer designations, and evidence of prior installations in comparable homes.
- If IAQ symptoms persist after service in West Allis, what are the next steps?
- Request follow-up diagnostics that include moisture mapping, ventilation testing, and combustion-gas checks. If issues persist, ask the installer for a written remediation plan and a timeline for follow-up visits.
- How should a homeowner evaluate whole-house air filtration or purifier options in West Allis?
- Look for filtration efficiency (MERV or HEPA rating), duct compatibility, and third-party test data. Verify installer experience with similar homes and ask for post-install testing or verification.
