Best ERV/HRV Ventilation Installers in Roanoke, VA
What to look for in ERV/HRV Ventilation Installation in Roanoke
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.

ERV/HRV Ventilation in Roanoke: ERV vs HRV + 62.2 sizing
A ventilation job is judged on the right device for the climate (ERV moves moisture, HRV doesn't), recovery efficiency, and ASHRAE 62.2 rate sizing — not just bolting on a fan. Here is what each of the 2 pros below publishes: In Virginia, HVAC contractors hold a DPOR HVA license — verify on dpor.virginia.gov before paying.

Why Roanoke homeowners need focused Indoor Air Quality care in Virginia
Roanoke's humid summers and Appalachian valley inversions can trap pollen, mold spores and combustion particulates, raising indoor exposures for sensitive households. Choosing the best indoor air quality HVAC companies in Roanoke, VA helps homeowners address mold in basements, outdated ventilation, and seasonal allergen loads.
How do Roanoke homeowners pick Indoor Air Quality upgrades that meet local rules and cut allergens?
- 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.
- Does the 2021 Virginia USBC affect ERV/HRV or ventilation upgrades in Roanoke?
- Yes. The 2021 USBC incorporates IECC provisions that can require mechanical ventilation or altered ventilation rates when modifying HVAC systems. Ask providers how proposed ERV/HRV installs meet the 2021 USBC ventilation and energy provisions.
- Will upgrading ventilation or adding humidification force an energy-code compliance review in Roanoke?
- Major HVAC alterations that change system efficiency or ventilation may trigger USBC energy compliance checks. Ask the contractor whether the proposed work requires energy-code documentation or post-work testing to comply with 2021 IECC provisions.
- How can a homeowner choose between in-duct UV-C and whole-house media filtration for pollen and mold control?
- Choose based on the target contaminant and system compatibility. Media filters remove particles; UV-C reduces biological growth on coils and in ducts. Look for providers who evaluate the duct system, indoor humidity, and existing filter MERV compatibility before recommending one or both options.
