What to look for in ERV/HRV Ventilation Installation in Johns Creek
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.

What Johns Creek homeowners most often ask about indoor air quality and HVAC upgrades
- 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.
- When do ventilation changes trigger a permit under the 2021 IECC in Johns Creek?
- Permits are typically required for ventilation changes that alter airflow or modify ductwork. Simple filter swaps usually do not need a permit. Larger projects, such as installing ERV/HRV units or altering duct runs, should be documented on permit applications and installed to code by a licensed contractor.
- Will improving ventilation and filtration help during Johns Creek's peak pollen and spore seasons?
- Yes. Upgrading filtration to higher-MERV whole-house filters and adding controlled mechanical ventilation or ERV/HRV units reduces indoor particle loads and moderates humidity swings during pollen and spore peaks. Combine filtration upgrades with dehumidification for best results. Verify installer plans include measured post-install improvements.
- How do I find a whole-house dehumidifier specialist in Johns Creek?
- Look for contractors who list whole-house dehumidifier installation in their service descriptions and who can show past jobs in similar homes. Ask for manufacturer-authorized dealer status, recent job photos, and references for installations in humid, slab-on-grade or crawlspace homes. Also request measured post-install humidity levels to confirm performance.
