Hydronic Zone Valve Repair — Georgetown TX
Zone valves control hot water flow to individual heating zones, allowing independent temperature control by room or floor. A failed zone valve causes that zone to lose heat entirely, or in the case of a stuck-open valve, to heat continuously regardless of the thermostat setting.
Zone valve failures come in two types: stuck closed (zone loses heat) and stuck open (zone overheats and won't turn off). Both have specific symptoms and repair approaches. We stock the most common zone valve models and actuators for fast replacement.
What's Included
We identify whether the valve, actuator, or end switch is the failure point.
Many zone valve failures are in the actuator alone — replaced without disturbing the valve body or piping.
When the valve body is leaking or seized, we replace the full assembly.
We verify the end switch is properly signaling the circulator pump after repair.
We verify each repaired zone responds correctly to its thermostat.
