TL;DR: Boiler repair in Utah County runs $200–$1,000 for most faults — igniters, pumps, zone valves, pressure issues — based on industry estimates. No heat in January is an emergency; call Utah Service Pros at 801-874-8479 for same-day diagnosis.
Why is the boiler not heating?
No-heat calls trace to a familiar list: failed igniter or thermocouple, a circulator pump that stopped moving water, a stuck zone valve leaving one floor cold, or pressure that drifted out of the 12–15 psi operating band. Each is a component repair — far cheaper than the boiler itself.
What does low boiler pressure mean?
Pressure below ~12 psi usually means a small leak somewhere in the loop or a feed valve issue; repeated drops mean the leak is real even if you cannot see it. Hard-water scale also accumulates in heat exchangers here, narrowing passages and forcing pressure and temperature swings — descaling restores flow, and softened make-up water prevents the recurrence.
Repair or replace an aging boiler?
Under 15 years: repair almost always wins. Past 15–20 years, cracked sections or a failing exchanger shift the math toward replacement, especially when a condensing unit’s efficiency gain pays back in fuel. The boiler hub covers the decision framework, and radiant floor heating shows what a healthy hydronic system can do.
