Commercial Pumps & Hydronic System Service — Vancouver Island
Hydronic systems are the circulatory system of a commercial building — quietly moving heat from where it’s generated to where it’s needed, floor by floor, zone by zone, unit by unit. A failed circulation pump, a waterlogged expansion tank, or a failing heat exchanger affects every tenant connected to that loop. Foster Heating & Cooling’s licensed A-Gas fitters and Red Seal certified technicians provide Vancouver Island’s commercial buildings with expert hydronic system service across the complete scope — pumps, tanks, heat exchangers, zone controls, and all distribution piping.
Hydronics is our core competency. As a full-service mechanical contractor with nearly a century of Vancouver Island experience, Foster handles hydronic systems as part of the complete building mechanical scope — alongside boilers, HVAC, refrigeration, and all ancillary equipment. One call. Complete accountability.

Our Commercial Pump & Hydronic Services
Circulation Pump Service & Replacement
Repair and replacement of inline circulation pumps, close-coupled pumps, and base-mounted end-suction pumps for commercial heating, cooling, and domestic hot water systems. We carry Bell & Gossett, Grundfos, Armstrong, and other leading commercial pump brands for fast turnaround.
Variable Speed Pump Drives
Variable frequency drive installation and service on hydronic pumps for energy savings and improved system control. VFD retrofits on existing fixed-speed pumps can deliver significant operating cost reductions on commercial building heating and cooling loops.
Expansion Tank Service & Replacement
Pressure expansion tank inspection, pre-charge verification, and replacement for hydronic heating and cooling systems. Waterlogged expansion tanks are a leading cause of pressure fluctuations, relief valve failures, and premature pump damage — we replace them before they cause system failures.
Heat Exchanger Service
Plate-frame and shell-and-tube heat exchanger cleaning, maintenance, and replacement for commercial and district heating applications. Regular heat exchanger cleaning restores efficiency and prevents scaling-related failures.
Zone Valves & Mixing Assemblies
Repair and replacement of zone valves, mixing valves, thermostatic valves, and actuators across commercial hydronic systems. Controls calibration and system balancing to ensure correct zone temperatures and flow distribution.
Primary/Secondary Pumping Systems
Design, installation, and service of primary/secondary and variable primary flow hydronic systems for commercial and institutional buildings. Proper primary/secondary design is critical for boiler and chiller protection and efficient system operation.
Hydronic System Balancing
Hydronic system commissioning and rebalancing to correct uneven heating or cooling distribution, excessive pump noise, or pressure-related issues across commercial buildings.
Chemical Water Treatment
Hydronic system flushing, cleaning, and inhibitor treatment to prevent corrosion, scaling, and biological growth. Water quality is critical for pump and heat exchanger longevity in commercial hydronic systems.
24/7 Emergency Hydronic Service
Round-the-clock emergency response for pump failures, pipe leaks, and hydronic system emergencies. When your building loop goes down, we dispatch immediately.
