Best ERV/HRV Ventilation Installers in Louisville, KY
What to look for in ERV/HRV Ventilation Installation in Louisville
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.

Why Louisville's humidity and older housing make Indoor Air Quality a year-round concern
Louisville's muggy summers and lingering humidity force mold growth and strain ventilation in older brick and shotgun homes. Homeowners shopping for the best plumbing services in louisville ky should prioritize providers offering humidity control, targeted filtration, and documented warranties.
What Louisville homeowners ask most about Indoor Air Quality services and local licensing
- 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 IECC affect ventilation or dehumidification upgrades in Louisville homes?
- Yes. Louisville follows the 2021 IECC for residential energy code, which changes airtightness and mechanical ventilation expectations. That tighter envelope often requires balanced ventilation or controlled whole-house dehumidification. Ask providers how a proposed ERV/HRV or dehumidifier integrates with the home's IECC-driven ventilation strategy.
- What evidence should a contractor provide that an ERV/HRV will improve indoor air quality in a tight Louisville home?
- Request an airflow balance plan, estimated fresh-air CFM, and pollutant-exchange expectations for the proposed ERV/HRV. Good proposals include projected humidity impact, filter ratings, and testable performance metrics. Contractors should also explain how the unit meets 2021 IECC ventilation needs for a tighter building envelope.
- When is it most important to schedule a dehumidifier inspection or installation in Louisville?
- Schedule humidity-focused work before Louisville's high-humidity months, typically spring through early fall, to prevent summer mold growth. Early scheduling helps avoid peak-season lead times. If basement or crawlspace moisture is already visible, request emergency service availability and a dehumidifier spec during the initial assessment.
