“House by the river was always muggy. Dehumidifier and duct sealing fixed it. They drove out from Seguin and were honest about the schedule.”
Newer Castroville homes are built so tight they trap stale air and humidity. An energy recovery ventilator brings in fresh air without throwing away the cooling you paid for.

Fresh air for tight homes
Modern Castroville construction seals up tight, which is great for the energy bill and rough on air quality — stale air, trapped humidity, and odors that have nowhere to go.
An ERV or HRV swaps stale inside air for fresh outside air while recovering most of the energy, so you ventilate without wasting your cooling.
Call (830) 587-5790A newer-home solution most people have not heard of — here is what it does for a tight Castroville build.
A well-sealed Castroville 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.
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.
In humid Medina 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.
Old Alsatian homes with thick walls and steep roofs rarely have ductwork that reaches everywhere. A ductless mini-split adds real, zoned cooling without tearing into a historic structure — the right answer for a house that was never built for central air.



From the historic Alsatian district along the Medina River to the homes just outside it, we reach Castroville on the extended run. A few of the areas:
“House by the river was always muggy. Dehumidifier and duct sealing fixed it. They drove out from Seguin and were honest about the schedule.”
“Our Alsatian home is a landmark and we were terrified of someone wrecking it. Moorhead modernized the wiring with real care, kept everything original-looking, and pulled the permit. Rare to find that respect.”
