Blank screens, lost programs after storms, and one dead station are controller or wiring jobs. We test the board and the field before we replace anything.
Hill Country acreage and HOA communities north of SA. San Antonio irrigation lives with limestone, caliche, pockets of black clay, Edwards Aquifer hard water, and long hot summers. Those conditions scale nozzles, walk heads out of grade, and punish weak valves.
Controller & Timer Repair in Boerne
This is a Kendall County route we run weekly. We do not treat Boerne like a generic Texas suburb — the soil, the water, and the HOA clock on this street are what set the repair.
How the visit goes
1) Test transformer, outputs, and field commons.
2) Repair wiring or replace the failed module.
3) Reprogram start times and station minutes.
4) Show you how to use seasonal adjust.
Local conditions
Hard water in Kendall County scales nozzles. Limestone and clay shift heads. If you want the neighborhood page, see sprinkler repair in Boerne.
What you can do before we arrive
Write down the station number, whether it fails only after rain, and whether the controller shows an error. Those three notes cut diagnostic time.
Parts and brands
Rain Bird, Hunter, Toro, Irritrol, Weathermatic, and K-Rain parts are not always interchangeable. On Boerne systems we document what is in the ground and match precipitation rates so one head does not drown a bed while another dusts the turf.
If a model is discontinued we install the closest hydraulic match and tell you what changed. We do not leave a mixed zone that cannot be scheduled honestly.

Quick question
My display is blank after a storm. Is the whole clock dead? Often it is the transformer or a surge on one output. We test supply before we replace the board.
When to call
Call Sprinkler Repair Tech if a zone will not shut off, water is pooling toward a foundation, or half the yard is offline in Boerne heat. Those are same-week jobs. Tune-ups and audits book on the next route day.
We are a call-first repair company. Technicians carry solenoids, diaphragms, spray bodies, rotors, and nozzle trees so most Boerne repairs finish in one visit. You get a plain-language explanation of what failed and how to water the soil you actually have.
Photograph the controller program before any upgrade. Label the valve box once we find it. Those two habits prevent a lot of repeat Boerne calls after the next landscaper or freeze.
