Your boiler needs 12–15 PSI cold. If it keeps dropping, there's a leak somewhere — radiator valve, fitting, expansion tank, or hidden in the floor. We find it.
Cold rooms, cold sections of baseboard, gurgling sounds. The system needs proper bleeding — and we identify why air is getting in.
Water isn't moving through the system even though the boiler is running. Pump is humming but not pumping, or completely silent. Common repair, usually same-visit.
Tank is waterlogged or the diaphragm has failed. Causes pressure spikes, dripping relief valves, and short cycling.
Visible water around the unit, dripping from connections, or moisture on the floor. Different causes — fittings, pump seals, heat exchanger. We find the source.
Boiler fires, runs briefly, shuts off, fires again — over and over. Wastes fuel and shortens the boiler's life. Usually a control or sensor issue.
Water dripping from the relief valve pipe. Safety device doing its job — but means something's wrong (high pressure, expansion tank, or temperature issue).
Boiler won't fire, pilot won't stay lit, error codes, or burner failures. Common on both standard and high-efficiency models.

Very common — and it's always a leak somewhere. Sometimes obvious (visible drip at a fitting), sometimes hidden (a radiator valve weeping under carpet, or a tiny leak in the heat exchanger). We pressure-test the system to find the source. Don't keep refilling — it accelerates corrosion inside the boiler.
Almost never — heat doesn't "leave" radiators. Cold spots are almost always trapped air or partial flow restriction. Usually fixable in 30 minutes with proper bleeding and balancing. Sometimes it's a stuck zone valve. We figure it out.
Depends on the unit and the issue. Hot water boilers typically last 15–25 years. Past that, repair vs. replace is a real conversation. We look at: pressure vessel condition, efficiency rating, parts availability, your fuel costs. If repair makes sense, we repair. If not, we tell you straight and walk you through replacement options.
Common multi-zone issue in Union County rental properties. Often a single zone valve or thermostat — fixable same-day without affecting other units. We communicate professionally with the tenant, fix the issue, and bill back to you.

40+ years of hydronic heating in Union County. We know modern systems and what fails.
We don't push replacements you don't need. Most hot water boilers have years of life left after a proper repair.
Most repair calls handled the day you call. 24/7 emergency in winter.
