Zone Valve Replacement
In a hot water heating system, zone valves decide which part of the house gets heat. When one sticks, you get a room that stays cold while the rest is warm, or a zone that will not stop heating. We test the valves at the boiler, find the one that has failed, and replace it.

Signs a Zone Valve Has Failed
A stuck valve shows up as heat in the wrong place, or no heat where you want it.
One cold room
A zone that stays cold while the rest of the house heats up normally.
Heat that will not stop
A zone that keeps warming even after the thermostat is satisfied.
A buzz or hum
A steady buzzing from the valve body near the boiler when a zone calls for heat.
No flow on a call
The thermostat clicks on but you never hear or feel that zone start to warm.
Test the Zones, Replace the One That Stuck
We start at the boiler, where the zone valves sit on the pipes that feed each part of the house. We watch what happens when each thermostat calls for heat, and check whether the valve opens, the motor runs, and water flows through that zone.
When we find the valve that has stuck or burned out, we isolate that section, replace the valve or its motor head, and confirm the zone heats and shuts off the way it should. You get the price before we swap anything.

Zone Valve FAQs
It is a small motorized valve on the heating pipes near your boiler. Each one opens to send hot water to a part of the house when that thermostat calls for heat.
Often only the motor head has failed and can be swapped without draining much of the system. We will tell you which your valve needs.
A stuck zone valve is a common cause. If the valve will not open on a call for heat, that zone never gets hot water.
Not always. We test both the valve and the thermostat call so we replace the part that actually failed.
