Repair, troubleshooting, and part identification. One failure mode or one component per post, written from what actually comes across our bench.
A hot-water machine that makes pressure but no heat is costing you on every job. Find out whether the coil is really the failure, what caused it, and whether repair protects uptime better than replacement.
A pump rebuild can put a commercial machine back to work, but it is not automatically the right answer. The real question is whether the pump has a sound foundation and whether the repair protects more revenue than it costs.
A hot-water machine that makes pressure but delivers cold water costs you on every job. Separate a true burner failure from a water-flow, fuel, or safety-control problem before you buy a single part.
A machine that runs fine but won't make pressure is the single most common call we get, and it is almost never the pump.
Two cheap parts that get confused constantly — and confusing them is how people end up replacing the wrong one twice.
Cold-weather burner failures follow a predictable order, and the answer is usually near the top of it.
