Boiler Installation and Replacement in St. George
Boiler installation and replacement is a sizing-and-piping job, not a furnace swap. We calculate the heat load room by room, match the boiler to your radiant zones, and commission the full system before we leave. Every installation is warranty-backed, with same-as-cash financing available through GreenSky.
Annual Boiler Maintenance in St. George
Boilers are among the most durable heating systems going — 20-plus years is common — but only with annual boiler maintenance. A fall service catches pressure, pump and valve wear before it takes out your heat mid-winter. VIP Club members get their tune-up included, plus priority scheduling and waived dispatch fees on service calls.

Why Choose Thompson Plumbing, Heating, Cooling & Electrical for Boilers in St. George
Boiler and radiant service is the quiet half of our heating business — and most of our Southern Utah competitors won’t touch these systems. We’re family-owned (not private-equity-backed), we carry Utah contractor license #6890689-5501, and every job is backed by warranty coverage with GreenSky same-as-cash financing available. Two offices — Washington and Cedar City — keep a qualified boiler technician close.
Frequently Asked Questions About Boilers in St. George
Yes — boiler and radiant service is a genuine Thompson specialty. Most Southern Utah HVAC companies won’t take these calls; our technicians do, from circulator pumps to zone valves.
Usually a zone valve, circulator pump or air lock in that loop — all fixable without replacing the system. We diagnose on the first visit and stock the common parts.
With annual maintenance, 20-plus years is common — longer than most furnaces. The trade-off is that a neglected boiler fails expensively, so a yearly fall service matters. VIP Club members get their tune-up included.
It depends on what your home was built for. Boilers deliver unmatched comfort through radiant heat, while furnaces are cheaper to install and easier to add cooling onto. If your home already has radiant, maintaining it usually beats converting it — we’ll give you honest numbers on both.
