ERV / HRV Systems in San Antonio

A newer-home solution most people have not heard of — here is what it does for a tight San Antonio build.

The Tight-House Problem

A well-sealed San Antonio home keeps conditioned air in, but it also traps stale air, CO2, cooking odors, and humidity. Cracking a window throws away your cooling. A recovery ventilator solves the trade-off.

How Recovery Works

An ERV or HRV exchanges stale indoor air for fresh outdoor air, transferring most of the heat — and with an ERV, the moisture — between the two streams. You get fresh air while keeping most of the energy.

ERV vs. HRV in This Climate

In humid Bexar County, an ERV is usually the right pick because it limits how much outdoor moisture comes in with the fresh air. We size it to the home and recommend the type that fits.

Why San Antonio Homes in Particular

Stone Oak, Alamo Ranch, Shavano Park, the sprawl past Loop 1604 — these subdivisions went up fast in the 1990s and 2000s on builder-grade 14-SEER equipment. Those units are now 15 to 20 years old and failing in batches. The classic call is the two-story where the upstairs never cools, because the original system was sized for square footage and ignored the stack of heat that builds on the second floor. We fix that with a real load calculation, a zoning damper, or a mini-split — not by selling you a bigger condenser and hoping.
