Boiler Repair for Steam & Hot Water Systems
Older homes throughout Philadelphia, Delaware County, and the Main Line are heated by steam and hot water boilers, and those systems need a technician who genuinely understands hydronics — not someone who only works on forced air.
Shepherd HVAC repairs cast iron and modern condensing boilers, steam and hot water alike, including circulators, zone valves, expansion tanks, low-water cutoffs, aquastats, and radiator and baseboard distribution problems.

What to Watch For
Common Signs Your Boiler Needs Repair
Boilers tend to complain before they fail. These are the symptoms worth acting on.
Cold radiators or baseboard
Air in the loop, a failed circulator, or a stuck zone valve — all repairable without replacing the boiler.
Pressure that keeps dropping
Usually a leak somewhere in the loop or a waterlogged expansion tank.
Banging or knocking pipes
In steam systems this often means trapped condensate or pitch problems; in hot water it points to air or flow issues.
The boiler keeps shutting down on safety
Low-water cutoff, high-limit, or ignition faults that need diagnosis rather than repeated resets.
Visible leaks or rust at the base
Section or fitting leaks that get worse quickly once they start.
Sky-high fuel bills
Short cycling, scale buildup, or a failed control strategy burning far more fuel than the house needs.
How It Works
Our Boiler Repair Process
- 1
Hydronic diagnosis
We check water pressure, temperature differential across the loop, circulator operation, zone controls, and combustion before recommending anything.
- 2
Safety verification
Low-water cutoffs, pressure relief valves, venting, and combustion readings all get tested — these are the components that keep a boiler safe.
- 3
Flat written pricing
You approve the repair price in advance, along with an honest assessment of remaining life on an older cast iron unit.
- 4
Repair and balance
After the fix we purge air, balance the zones, and confirm every radiator or loop is heating as it should.
Pricing
What Affects the Cost
Boiler repairs range from simple part swaps to significant hydronic work.
Component involved
A thermocouple or aquastat is minor; a circulator, gas valve, or heat exchanger is major.
Steam vs. hot water
Steam systems have traps, vents, and pitch considerations that add diagnostic time.
Age and parts availability
Parts for boilers over thirty years old can be scarce and expensive.
Zone count
Multi-zone systems have more valves, circulators, and controls to test.
Water quality and scale
Heavy scale or sediment may require flushing along with the repair.
