A heater that won't fire, trips a breaker, or short-cycles is usually a parts-level problem, not a sign you need a whole new unit. This page covers what to check before you call, what repair typically costs by heater type, and why hard local water plays a bigger role here than in most markets.
Quick checks before you call
- Check the display or error code. Most gas and electric heaters show a code when they won't fire — write it down before you call, it can save a diagnostic visit.
- Confirm the pump is actually running. A heater won't fire without water flow — if the pump isn't running, that's the real problem, not the heater.
- Check the breaker and gas supply. A tripped breaker or a gas valve someone shut off (after a service visit, a storm, or seasonal shutdown) is a common false alarm.
- Listen for ignition attempts. A gas heater that clicks and tries to light but fails often points to a flame sensor, pressure switch, or gas valve issue rather than a major failure.
- Note whether it's intermittent or constant. A heater that short-cycles (fires, then shuts off) versus one that won't fire at all point to different likely causes, and telling the technician which one saves time on-site.

Why St. George heaters need extra attention
St. George's water runs hard — roughly 342 ppm, or about 20 grains per gallon. Hard water scales heat exchangers faster than soft-water regions, and scale buildup is one of the more common local reasons a heater loses efficiency or starts short-cycling before it actually fails outright. A technician familiar with the area will often check for this before assuming a part has failed.

Common Questions
How much does pool heater repair cost in St. George?
$166–$799, averaging $477, as of September 2026. The heater type matters: gas heaters run $150–$750, electric heat pumps $200–$1,200, and solar heaters $50–$400 to repair.
Why is my saltwater pool heater more expensive to repair than a chlorine one?
Saltwater systems need corrosion-resistant components, which cost more — saltwater heater repair runs $500–$1,500 versus $165–$790 for a chlorine system, both as of September 2026.
Does hard water affect pool heaters in St. George?
Yes — St. George's water runs roughly 342 ppm (about 20 grains per gallon), and scale buildup inside a heat exchanger from hard water is one of the more common local causes of reduced efficiency or short-cycling. Ask a technician about descaling if your heater is losing efficiency rather than fully failing.
Should I repair or replace my pool heater?
Angi's 2026 data puts full replacement at an average of $2,800 — no published range was available alongside that average. As a general guide, a straightforward parts repair (flame sensor, pressure switch, gas valve) on an otherwise working heater is almost always worth doing before considering replacement; a heater with a cracked heat exchanger or that's reached the end of its typical service life is a different conversation.
