Fresh Air Without the Energy Penalty
An HRV (Heat Recovery Ventilator) or ERV (Energy Recovery Ventilator) brings fresh outdoor air into the home while exhausting stale indoor air — and recovers 70–80% of the heating or cooling energy from the outgoing air before it leaves. You get fresh air without throwing your conditioned air out the window. In a New Braunfels summer, that means ventilating without dumping your cold air and your AEP money outside.
Why Tight Homes Need Mechanical Ventilation
Modern construction and energy retrofits seal homes up tight — new windows, added insulation, sealed crawlspaces. That's great for the energy bill, but a sealed home traps stale air, cooking odors, humidity, CO2, and VOCs with nowhere to go. The old drafty house "breathed" on its own. A tight house doesn't — it needs mechanical ventilation to stay healthy. An ERV/HRV is how you get the efficiency of a tight home without the stale-air problem.
Signs Your Home Needs Ventilation
- Stale, stuffy air — especially in the morning or after the house has been closed up
- Lingering cooking and bathroom odors
- Persistent humidity even with the AC running
- Condensation on windows
- The house was recently air-sealed, re-insulated, or had new windows installed
- Stuffiness or headaches that ease when you open a window
How We Size It
We assess your home's square footage, tightness, and occupancy to size the unit and recommend ERV vs. HRV. In humid South Texas, an ERV is usually the right call because it recovers humidity along with temperature — helping keep moisture out of the house in summer. We do the calculation and give you the honest recommendation.
