Best ERV/HRV Ventilation Installers in Dundalk, MD
What to look for in ERV/HRV Ventilation Installation in Dundalk
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 Dundalk homeowners ask about hiring an "Indoor Air Quality" HVAC contractor
- 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.
- How do I find a ventilation (ERV/HRV) specialist for Dundalk homes?
- Look for contractors who document ERV/HRV project experience and manufacturer training. Ask for past Dundalk installations, written airflow calculations, and references. Verify that the contractor can size and balance systems for older ductwork common in the area. Request a scope that includes humidity control, core maintenance, and any local permit handling.
- What should I ask before installing a whole‑house air purifier in Dundalk?
- Ask about compatibility with existing HVAC systems and the purifier's tested removal rates for particles and VOCs. Request an on-site evaluation that includes duct condition and filter staging. Confirm whether the installer measures indoor particulate levels before and after installation. Also ask how the unit will be serviced in Dundalk's humid, coastal environment.
- When is UV‑C light installation recommended for Dundalk homes?
- UV‑C is recommended when microbial growth on coils or in ductwork is suspected, especially in Dundalk's humid coastal climate. Contractors should show evidence of safe UV‑C placement, impact on coil cleanliness, and maintenance intervals. UV‑C is a complement to filtration and dehumidification, not a standalone fix for mold or persistent moisture problems.
