“Old panel on a long run, flickering lights. They diagnosed the voltage drop, upgraded the panel, added surge protection. Knew their stuff.”
Newer Devine 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 Devine 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 Devine build.
A well-sealed Devine 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.
No natural gas out here means propane or heat-pump heat. We service both, with the heat exchanger and CO checks done every visit — which matter even more in a tight rural home far from quick help.



From the town center to the fields and ranch acreage along IH-35, we reach Devine on the extended run. A few of the areas:
“Old panel on a long run, flickering lights. They diagnosed the voltage drop, upgraded the panel, added surge protection. Knew their stuff.”
“Farm outside Devine on a well, power out every storm. Moorhead sized a Generac for the pump and AC. Never lost water again, and they were honest about the drive from Seguin.”
