The brain of your system deserves attention
The controller is the least expensive major component of a sprinkler system and the cause of a remarkable share of service calls. A timer with a scrambled program waters at midnight instead of 5 a.m. A lightning-fried board runs zones randomly or not at all. A dying backup battery loses the program with every power flicker — and Florida power flickers. Before you assume the problem is underground, check the box on the garage wall: a large percentage of "sprinkler problems" are controller problems, and controller problems are the fastest fixes we do.
What fails in controllers
Lightning and power surges are the number one killer in Central Florida — a nearby strike sends voltage through the valve wiring straight into the board. Symptoms range from a completely dead display to individual zone terminals that no longer fire. Mechanical dial timers wear out: the clock motor dies, the pins break, the dial slips. Digital units suffer button failure, display fade, and corrupted memory. And the humble 9-volt backup battery, dead for years unnoticed, means every outage wipes the program — which is why so many systems run a "mystery schedule" nobody set. We diagnose at the board level: output voltage per terminal, transformer function, and program integrity.
Repair versus replace
A controller with a dead backup battery, a bad transformer, or a corrupted program is a repair — often under an hour. A board with multiple dead zone terminals after a surge is usually a replacement, since board-level repair costs more than a new unit. And a working-but-ancient mechanical timer is a judgment call: we can keep it running, but a modern digital or smart controller gives you seasonal adjustment, rain sensor compatibility, and app control for not much more than the service call. We lay out both numbers and let the math decide.
Reprogramming is half the service
Whether we repair your controller or install a new one, the visit includes full reprogramming — because a correctly wired controller running the wrong schedule is still a broken system. We set run times for your zones' actual precipitation rates, start times for early morning, watering days for current county rules, and seasonal adjust percentages that make sense. We also label every zone wire at the terminal strip, so the next tech (even if it is us) is not guessing which wire is the front lawn.
Protecting your controller from Florida storms
Lightning is the leading cause of controller death in Central Florida, and basic protection is inexpensive. A surge protector on the controller guards against spikes coming through the power line; proper grounding gives surges a path that is not through your circuit board. These do not make the controller lightning-proof — a direct strike overwhelms everything — but they handle the far more common nearby strikes and grid fluctuations that kill most boards. We recommend surge protection with every controller replacement, and we can retrofit it to existing units. It is the cheapest insurance in irrigation.
How it works
Bench diagnosis. We test the controller's outputs, transformer, and program — and verify the problem is the controller, not the field wiring. Repair or replace quote. Written price for either path before we proceed. Fix. Board-level repairs, transformer and battery replacement, or full controller swap. Reprogramming. Complete schedule rebuild for your zones and current watering rules. Walkthrough. You learn the basic operations — manual run, rain delay, seasonal adjust.
What it costs
Timer and controller repair in Kissimmee typically runs $150-$450. Battery, transformer, and reprogramming service sit at the low end; full controller replacement with a modern digital unit sits higher. Prices vary by unit and wiring condition — diagnosed and quoted in writing before work. If a smart controller upgrade makes more sense than repairing an obsolete timer, we will show you that math too.
Your system is only as smart as its controller
A malfunctioning controller wastes water, stresses the lawn, and makes the whole system feel unreliable — when the fix is often a single visit. If your timer is acting strangely, was hit by a storm, or is old enough to vote, send the form. We will sort out the brain of your system.
Label your zones
A small thing with outsized value: labeled zone wires at the controller. "Front lawn," "beds east," "drip" — written on the terminal strip or on a card inside the controller door. Unlabeled controllers turn every service call into a guessing game, and they make it impossible for you to run a specific zone manually when you need to. We label every controller we service, and we suggest you check yours: if the wires are a mystery, the next lightning storm or service visit will be harder than it needs to be. Ten minutes with a label maker, years of easier service.
