Best ERV/HRV Ventilation Installers in Marietta, GA
What to look for in ERV/HRV Ventilation Installation in Marietta
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.

Which Indoor Air Quality fixes do Marietta homeowners ask about most?
- 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.
- Is a permit required for an ERV or HRV ventilation install in Marietta under the 2021 IECC?
- Probably, yes. Ventilation system work that alters ducting or mechanical ventilation often triggers permit review under the 2021 IECC, which Georgia follows. Confirm permit needs with the city building department and ask the contractor to handle permit filing if required.
- How can homeowners verify a contractor follows 2021 IECC ventilation requirements?
- Ask for a written ventilation plan that cites IECC ventilation rates and shows calculations for outdoor air. Contractors should provide equipment specs and installation notes demonstrating compliance with the 2021 IECC.
- What factors most affect IAQ pricing in Marietta?
- System size, duct access, and whether work requires permits or code compliance drive price. Existing equipment condition and the need for ventilation upgrades under the 2021 IECC also affect scope and labor time.
