Heating & cooling
Maintain a whole-home boiler
Combustion, venting, pressure, pumps, controls and water quality make annual boiler service a professional task.
Recommended timingProfessional service every year
What to do
- Schedule annual service with a boiler-qualified technician before the heating season.
- Between visits, keep the boiler area clear and observe the normal pressure and temperature shown in the owner manual.
- Check visible piping, radiators or manifolds for leakage, corrosion and air-related noise.
- Follow the manual for any homeowner-level condensate neutralizer, low-water cutoff or system-water checks; do not add water repeatedly without finding the cause.
Do not open combustion, gas, electrical or pressurized-water components. Use a qualified boiler technician.
