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 is the busiest season for Norfolk IAQ companies, and how does that affect scheduling ERV/HRV installations?

Norfolk IAQ demand peaks in warm, humid months when homeowners seek moisture control. Schedule planned ERV or HRV installs before summer humidity rises to avoid long lead times. Booking in spring typically improves availability and may reduce scheduling delays.

Do ERV/HRV ventilation upgrades in Norfolk usually require duct or mechanical permits under the 2021 USBC?

They often do when the work involves new duct runs or modifications to the mechanical system. The 2021 USBC emphasizes ventilation and mechanical compliance. Confirm permit requirements with Norfolk building officials and ensure the contractor includes permit handling in the scope.

Does replacing ventilation or adding a whole-house dehumidifier trigger requirements under the 2021 Virginia USBC in Norfolk?

Potentially. The 2021 Virginia USBC and its 2021 IECC provisions affect mechanical ventilation and envelope work. Local permit requirements depend on the scope of work and whether mechanical or duct changes are made. Ask the contractor which permits they will obtain and confirm permit filings with the city.
