Services We Provide
Radiant Floor Heating Installation
Crawlspace retrofit, aluminum-plate, staple-up, and slab radiant systems — heat-loss modeled and balanced loop-by-loop.
Hydronic Diagnostics & System Repair
European-trained diagnostics for uneven heat, air locks, circulation, zoning, and bad workmanship on inherited systems.
Panel Radiators & Comfort Heating
Low-temperature panel radiators and designer verticals — quiet, clean, room-by-room comfort engineered to actual heat loss.
Pumps & Zoning Manifolds
Stainless manifolds, ECM circulators, mixing assemblies, hydraulic separation, and properly engineered zoning.
Radiant & Hydronic Engineering
Radiant Floor Heating Installation
ABC Service installs every flavor of hydronic radiant floor — crawlspace retrofits with aluminum heat-transfer plates, staple-up assemblies under existing subfloors, slab-on-grade pours for new construction, and gypcrete or thin-slab overlays for remodels. Each layout is engineered from a room-by-room heat-loss calculation, with loop lengths, tube spacing, and supply temperatures matched to the floor finish and the building envelope.
Hydronic Diagnostics & System Repair
A large share of the hydronic work we do is fixing other people's installations. Uneven heating, cold zones, air-locked loops, short-cycling boilers, gurgling pipes, runaway return temperatures, oversized circulators fighting undersized piping — these are not equipment failures, they are design and workmanship failures. Our team has seen them all, and we know how to unwind them without ripping the system out.
Panel Radiators & Comfort Heating
European-style panel radiators deliver room-by-room comfort that forced-air simply cannot match — silent, dust-free, and tunable to the degree on every wall. ABC Service specifies low-temperature steel panel radiators and designer vertical radiators from Buderus, Runtal, Myson, and Jaga, sized to each room's actual heat loss rather than off a generic chart.
Manifolds, Pumps & Zoning
The manifold cabinet is the brain of a radiant or panel-radiator system. We build stainless or brass manifolds with per-loop flow meters, electronic actuators, isolation valves, and integrated air vents — laid out so every loop can be read, balanced, and serviced individually. Pumps are sized to the actual head loss of the loops they feed, not bought oversized 'just in case.'
Why this is worth doing right.
European hydronic discipline
Decades of European radiant and panel-radiator experience applied to Bay Area homes — design, install, and corrective work.
Fixes inherited mistakes
Most hydronic complaints aren't equipment failures — they're design and workmanship failures. We unwind them without a tear-out.
Silent, even comfort
No registers, no fan noise, no blown dust. Radiant and panels deliver warmth you feel rather than hear.
Pairs with heat pumps
Low-temperature radiant and panels are the ideal emitter for modern heat pumps and condensing boilers — engineered for the long run.
