Hydronic System Components We Service
Circulator Pump
The circulator pump moves hot water from the boiler through your pipes and radiators. When it fails, no heat reaches the living space. Signs: heat only near boiler, pump running but no heat, or pump not running at all. We stock replacement pumps for all major brands and can usually replace same day.
Zone Valves
Zone valves control hot water flow to specific areas of your home or building. A failed zone valve means one area won't heat even when others work fine. We repair and replace Taco, Honeywell, Caleffi, and all major zone valve brands.
Expansion Tank
The expansion tank absorbs pressure changes as water heats and cools. A waterlogged expansion tank causes boiler pressure to spike repeatedly, triggering the pressure relief valve. Replacement is quick and prevents serious system damage.
Baseboard Heaters
Baseboard units distribute heat by convection as hot water passes through. Fins clogged with dust, airlocked sections, or faulty zone valves are the most common causes of baseboard heating failure. We clean, bleed, and repair baseboard zones effectively.
Radiant Floor Heating
In-floor radiant systems circulate hot water through tubing in the floor. Leaks, air locks, pump failures, and manifold issues are common problems. We diagnose radiant systems with pressure testing and thermal imaging.
