Tell us what’s happening
What is your boiler doing?
Describe what you’ve noticed as best you can. If you know when it started or which rooms are affected, that helps. We’ll investigate the cause; you do not need to diagnose it.
- Boiler will not fire
- The system is not providing heat when needed.
- One cold room or zone
- Some radiators or areas stay cold while others heat.
- Leaks or pressure changes
- Describe visible water or pressure changes without handling hot piping.
- Household hot-water changes
- Mention tap-water problems if the boiler also supplies household hot water.
What happens next
Find the cause. Review the repair. Check the result.
Investigate the concern
We review hot-water heating operation, zone calls, controls, circulators and relevant pressure/expansion conditions. Confirm fuel and system type; oil and steam work are not assumed.
Explain the finding and proposed work
We discuss the repair, its price and whether further investigation, a specific part or a return visit is needed.
Approve the work, then check operation
You decide whether to proceed. After the approved repair, we check operation and explain what was done. A needed part or return visit is discussed before it is arranged.

Sign up for Maintenance Plan →What affects the repair price? A boiler that will not fire, one cold zone and a visible leak can involve different controls, pumps, valves or piping. The investigation and retained-system condition shape the proposed repair.
When there are options
Repair or replacement?
When repair may make sense
The identified fault can be addressed and the remaining equipment can serve your needs. Review the repair price and what the work will resolve.
When to compare replacement
Compare the identified repair with boiler condition, history and the heating needs of the house. A replacement plan should explain the connected components that stay.

Getting ready
Questions before your visit
Review the common questions and use the symptom checker for guidance before requesting a visit. A technician will need to diagnose the cause.
What if the boiler runs but one heating zone stays cold?
Checks may involve the thermostat call, zone controls, valves and circulator rather than the boiler alone. Pressure changes can require a different investigation of expansion and connected piping. Confirm your boiler, fuel and distribution type during follow-up; steam and oil work are not assumed from this page.
What should I prepare before the visit?
Record safely visible messages, water or pressure changes. Keep access clear and leave the equipment closed. Do not keep adding water to a system losing pressure or try to force a safety valve closed.
Can the repair be completed during the visit?
That depends on the finding, work and parts needed. We explain any specific part, further investigation or return visit with the proposed work before you approve it.
Do you service steam boilers?
We’ll ask about the manufacturer and model when we follow up so the appropriate support can be confirmed. This page describes hot-water heating systems; it does not promise service for every steam boiler.
Will the work affect household hot water?
Tell us if the boiler serves an indirect tank or combination hot-water arrangement. We discuss the connected system and any interruption relevant to the proposed work.
