“Newer build, hot upstairs every afternoon. They measured the load and fixed the airflow instead of pushing a bigger unit. Honest and fair, drove out without complaint.”
When one alarm sounds, they should all sound. We install hardwired, interconnected smoke and CO detectors throughout Smithson Valley homes — the coverage code requires and safety demands.

Hardwired + interconnected
Battery alarms scattered around the house are better than nothing, but hardwired, interconnected detectors are the real protection — when one senses smoke or CO, every alarm in the Smithson Valley home goes off at once.
We install whole-home coverage to current code, including the CO protection gas and attached-garage homes need.
Call (830) 587-5790Not glamorous, genuinely life-saving. Here is what whole-home detection involves in Smithson Valley.
Interconnected detectors all sound together, so an alarm in the garage wakes you in the back bedroom — the difference that matters most at night. We hardwire them with battery backup throughout the Smithson Valley home.
Carbon monoxide protection matters in homes with gas appliances, a furnace, or an attached garage. We place CO detection correctly so it catches a leak — including from that cracked heat exchanger we check on heating calls.
Code specifies detectors in and outside every sleeping area and on each level. We install full coverage and document it — important for safety, insurance, and resale on a Smithson Valley home.
The newer homes filling in came with builder-grade systems sized to a price — and on a big Hill Country lot with lots of glass, that shows up as a hot upstairs fast. We run a load calculation and fix the airflow once the warranty lapses.
