Boiler service requires looking beyond the boiler itself.
A boiler heating problem can involve combustion, controls, circulation, pressure, venting or the heat-distribution system. Central HVAC evaluates the complete installation before recommending repair or replacement.
Gas and oil boiler service
Central HVAC services residential gas-fired and oil-fired boiler systems. Depending on the installation, the boiler may supply hot water to baseboard radiation, radiators or other hydronic heating equipment, or it may produce steam for a steam distribution system.
Gas Boilers
Diagnostics, operating and safety checks, control troubleshooting, repair and replacement of residential gas-fired boiler systems.
Oil Boilers
Diagnostics, operating checks, service and replacement planning for residential oil-fired boiler heating systems.
Hot-Water / Hydronic Heat
Evaluation of boiler operation, circulators, zone controls, system pressure, expansion components and hot-water distribution.
Steam Heat
Evaluation of residential steam-boiler operation, controls and distribution-system conditions that affect heating performance.
Common boiler problems we evaluate
- Boiler will not start or does not produce heat
- Some zones, baseboards or radiators are not heating properly
- Boiler cycles repeatedly or shuts down unexpectedly
- Water leaking around the boiler or heating-system components
- Unusual banging, knocking, gurgling or other system noise
- Pressure or temperature problems
- Circulator, zone valve, aquastat or control problems
- Older boiler with increasing repair or fuel costs
Boiler, controls and distribution all matter
Reliable boiler performance depends on more than the heat exchanger or burner. The installation may include circulators, zone valves, expansion tanks, pressure controls, aquastats, low-water controls, thermostats, venting or chimney connections and a network of baseboards, radiators or steam piping.
When a system is not heating correctly, those components and their interaction should be considered before deciding that the boiler itself needs replacement.
Boiler repair or replacement?
An older boiler does not automatically need to be replaced. We consider its age, physical condition, reliability, repair history, efficiency, controls, venting and the condition of the overall heating system.
When replacement makes sense, the new boiler should be selected and installed based on the heating load and existing distribution system—not simply by matching the input rating of the old equipment.
Combustion and venting problems require professional evaluation
Gas and oil appliances involve fuel, combustion products and high-temperature equipment. If you smell gas, see smoke or soot, have a carbon-monoxide alarm, or suspect a combustion or venting problem, stop using the equipment and follow the appropriate emergency procedures rather than attempting a repair yourself.
Tell us about your heating system
If possible, provide the boiler manufacturer and model, approximate age, fuel type, whether the system is hot water or steam, and a description of the problem. Photos of the boiler and surrounding piping are helpful.
