Define the repair
The written scope should name the diagnosed appliance or zone component and the checks needed afterward. A cold room alone does not establish a failed boiler.
Request boiler service for a property in King City. Include the equipment, the problem or planned work, and your location so the request can be reviewed.
A boiler fault may be repairable without replacing the hydronic distribution, while a new boiler still has to work with retained zones and emitters. Establish the actual failed components and design requirements before comparing options.
Supply the model, fuel, fault history, zone layout, and hot-water role. Ask for distribution findings to be identified separately from appliance condition.

The written scope should name the diagnosed appliance or zone component and the checks needed afterward. A cold room alone does not establish a failed boiler.
Radiators, floor loops, pumps, valves, and controls affect replacement design. Ask how the proposed appliance serves their requirements and the building load.
Include venting and fuel work where relevant, circulation and control changes, removal, and commissioning. Filling and pressure procedures require appropriate service personnel.
Review the confirmed repair, related condition, and full replacement design. Require an explanation of what remains installed and how all relevant zones will be checked before a major equipment decision.
Leave fuel, combustion, electrical, and pressure-system work to a qualified contractor. Do not adjust safety devices or repeatedly add water to a system with an unexplained leak or pressure loss.
Send the property location, equipment information, and requested work for review.
