Best ERV/HRV Ventilation Installers in San Diego, CA
What to look for in ERV/HRV Ventilation Installation in San Diego
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 San Diego's Coastal Humidity Makes "Indoor Air Quality" Checks Essential
San Diego's coastal humidity and mild winters raise indoor mold and allergen risk, increasing demand for indoor air quality inspections. Homeowners seeking the best best indoor air quality HVAC companies in San Diego, CA should prioritize certified testing, ventilation upgrades, and humidity control. Seasonal sea breezes can shift pollutant patterns near the coast.
How long should an "Indoor Air Quality" inspection take in San Diego — and who responds fastest?
- 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 Title 24 rules affect ERV or HRV ventilation upgrades in San Diego?
- Title 24 influences required ventilation rates and energy performance for mechanical systems. Providers should show how an ERV or HRV meets Title 24 limits and affects whole-house energy numbers. Ask for documentation linking the proposal to Title 24 compliance.
- Do San Diego permits or inspections apply to ERV/HRV installations?
- Permit requirements vary with scope and whether work alters the building envelope or mechanical systems. Confirm permit needs with the contractor and local building department. Licensed contractors typically handle permit filings as part of the proposal.
- How do I compare whole-house filter upgrade proposals in San Diego?
- Compare proposed MERV ratings, pressure drop estimates, and whether the existing fan can handle the upgraded filter. Ask each provider for a measurement of static pressure and an explanation of how the change affects HVAC efficiency.
