Best ERV/HRV Ventilation Installers in Charleston, WV
What to look for in ERV/HRV Ventilation Installation in Charleston
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 much should Charleston homeowners expect from a licensed "Indoor Air Quality" HVAC contractor?
- 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.
- Do homeowners need ERV or HRV ventilation in Charleston, given the humid summers?
- ERV and HRV systems can improve ventilation without losing conditioned air, but designs must account for summer moisture. In Charleston, choose ERV/HRV installations that include humidity control or operate with dehumidification to prevent introducing excessive outdoor moisture during hot months.
- How should homeowners prepare for IAQ work before Charleston's cold, damp winter?
- Schedule humidifier balancing and ventilation checks in autumn to avoid winter condensation and dry-air problems. Technicians should inspect ducts, test humidity control, and adjust equipment sequencing before cold weather. Preparing ahead reduces emergency visits and stabilizes indoor relative humidity during cold spells.
- What questions should I ask to verify a contractor's IAQ equipment warranties and service terms?
- Ask about the manufacturer's warranty length, what work voids the warranty, and whether the contractor provides a service or installation warranty. Request warranty documents in writing and ask about regular maintenance requirements. Verify whether emergency repairs are covered and how service calls are billed.
