This is a common radiator heating imbalance. Often, trapped air in the system or uneven pressure prevents hot water from circulating properly to all radiators.

Our comprehensive tune-up includes cleaning critical components like the flame sensor and heat exchanger, checking for gas leaks or electrical issues, testing safety controls, calibrating your thermostat, and measuring system efficiency. This proactive service helps prevent common local problems like imbalances and short cycling, ensuring reliable performance all season.
