“Older home near the courthouse with a tired panel. They upgraded it, pulled the permit, kept the character. Straight, clean work.”
When one alarm sounds, they should all sound. We install hardwired, interconnected smoke and CO detectors throughout Karnes City 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 Karnes City 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 Karnes City.
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 Karnes City 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 Karnes City home.
Outside town it is Karnes County ranch land on well, septic, and propane. We service rural systems, fix long service runs, and size generators to carry the AC and the well pump through outages.
