Best ERV/HRV Ventilation Installers in Boulder, CO
What to look for in ERV/HRV Ventilation Installation in Boulder
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.

Boulder's seasonal swings in heating and cooling increase indoor pollutant concentration, so air filtration and ventilation choices matter for homes. Homeowners seeking best indoor air quality HVAC companies in Boulder, Colorado should prioritize providers offering emergency service, warranties, and clear testing plans.
How do Boulder homeowners pick an Indoor Air Quality HVAC contractor who’s right for their house?
- 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 ERV or HRV ventilation installs in Boulder?
- Answer: Permit rules for ERV/HRV installations depend on the scope of mechanical work and local code enforcement. Ask the installer if the project triggers a mechanical permit or duct alteration permit with Boulder building officials. Ensure the contractor includes permit handling and an itemized scope in the written estimate.
- How do seasonal wildfire smoke events change what to ask an IAQ contractor in Boulder?
- Answer: During smoke season, ask about high-efficiency filtration, fresh-air intake control, and the ability to switch to recirculation modes quickly. Confirm the contractor can install and commission filters and ventilators that balance filtration with required fresh air. Also ask for recommendations on temporary measures while waiting for install.
- When should Boulder homeowners schedule humidifier or dehumidifier work to avoid seasonal issues?
- Answer: Schedule humidification or dehumidification work ahead of the season when symptoms begin. In Boulder, lower winter humidity and summer storm-linked moisture both create distinct needs. Book inspections before heating season and before peak summer storms to avoid long wait times and to allow time for any required duct or ventilator adjustments.
