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 Chapel Hill require permits for installing an ERV/HRV or major ventilation alterations under the 2021 NC Energy Conservation Code?

Yes. Major ventilation upgrades and equipment changes typically require permits under the 2021 NC Energy Conservation Code. Major ventilation upgrades and any work that changes mechanical ventilation rates may trigger permit requirements under the 2021 NC Energy Conservation Code adopted by North Carolina. Contractors familiar with the code can identify when a permit is needed and submit compliant ventilation specifications. Homeowners should request permit confirmation before work begins.

What signals show a Chapel Hill contractor is experienced with whole‑house filtration or whole‑home air cleaners?

Experienced installers will discuss MERV ratings, pressure drop, and compatibility with the home’s HVAC fan and static pressure. They should offer pre‑ and post‑installation filter performance checks and explain maintenance intervals. Request documented examples of previous Chapel Hill installations and manufacturer dealer or training affiliations for the installed equipment.

What factors most affect IAQ project pricing in Chapel Hill without quoting dollar amounts?

Project cost depends on equipment type, home size, complexity of ductwork or electrical work, permit requirements, and seasonal demand. Older homes needing duct repairs or code‑required ventilation changes add labor. Ask each contractor to itemize scope, permits, and verification testing to compare bids fairly for Chapel Hill properties.
