Homeowners cannot diagnose and fix dangerous hydronic boiler pressure spikes without expensive emergency service calls

Homeowners with hydronic heating systems face sudden, unexplained pressure increases (16-35 psi) during operation that risk system damage and safety hazards. They lack diagnostic tools and knowledge to identify root causes like failing expansion tanks, forcing them to call expensive emergency HVAC technicians. Current solutions (generic HVAC forums, trial-and-error repairs) are slow, unreliable, and leave homeowners vulnerable to costly system failures during winter.
