Pool Heater Repair & Replacement
Heat pumps, gas heaters, and solar — diagnosed right, fixed honestly, sized correctly.
Free on-site inspection. Written estimate before any work.
What Heater Repair includes
Heater not heating, throwing an error code, leaking, or shutting off too soon? We diagnose heat pumps, gas heaters, and solar across every major brand — Hayward, Raypak, Pentair, AquaCal, Jandy. We start with the cheapest likely cause (a clogged filter chokes flow and is behind a huge share of "dead" heaters), then give you an honest repair-or-replace recommendation. Any repair or component replacement is quoted in writing, approved by you first, and performed by our trusted licensed partners. We also catch what most companies miss: bad water chemistry and wrong-sized, mis-plumbed equipment quietly destroying your heater.
- ✓Full heater diagnostic — flow, ignition, error codes, pressure
- ✓Filter/flow check first (the #1 cause of a heater that won't fire)
- ✓Error code analysis (flow faults, HP/high-pressure, ignition lockout)
- ✓Heat pump compressor + coil service scope
- ✓Gas valve, burner, and igniter service scope
- ✓Heat exchanger inspection — repair-or-replace recommendation
- ✓Honest repair-vs-replace math (new heater ≈ $5K–$7K; major component ≈ $4K–$5K)
- ✓Correct heater sizing + diverter/plumbing check to stop premature failures
- ✓Repairs and component replacement performed by our trusted licensed partners
South Florida homeowners with a heater that won't heat, throws codes, leaks, or is 10+ years old and due for a repair-or-replace decision.
What to expect: our heater diagnostic
Most heater "failures" aren't what the homeowner thinks. A heater that won't fire is usually starved for flow, not broken — so we work a fixed sequence from cheapest cause to most expensive, and you see the finding at each step before anyone talks about parts.
- 1Filter & flow check
We pull the filter cartridge and run the system first. A clogged filter chokes off the water flow almost every heater needs to ignite — and a huge share of "dead heater" calls end right here, fixed for the price of a rinse.
- 2Read the error code
We read the fault on the display — a flow fault (often a code in the 100s), HP/high-pressure, or an ignition lockout — to pinpoint the system at fault instead of guessing.
- 3Component test
Depending on the code we test the igniter, flame sensor, pressure switch, and gas valve on gas units, or the compressor, coil, and refrigerant pressures on heat pumps.
- 4Heat exchanger inspection
We check the exchanger for etching, scale, and leaks. This is the part that decides repair vs. replace — at $4,000–$5,000 it's usually the trigger to put money toward a new unit.
- 5Sizing & plumbing check
We confirm the diverter valve is set correctly and the heater is matched to your flow rate. Wrong sizing and a mis-used diverter are what quietly blow heat exchangers and pumps — we catch it before it costs you thousands.
- 6Written quote + recommendation
You get a flat-rate quote in writing and an honest repair-or-replace call. Nothing is ordered or installed until you approve the number.
Repair or replace? The honest math
Most heater repairs land between $250 and $1,800 — sensors, igniters, flow switches, relays, gas valves, control boards. Those are worth fixing on a heater that still has life in it. Where the decision flips is the two big internals: a failed heat exchanger or compressor runs $4,000–$5,000, and a brand-new, more efficient heater installed is $5,000–$7,000. When the repair gets that close to a replacement, we'll tell you straight that the new unit is the smarter spend.
Our rule of thumb: repair if the heater is under ~10 years old and the fix is under ~30% of a new unit; replace if it's 15+ years old, the exchanger or compressor is gone, or the repair crosses ~50% of replacement. You always get the numbers in writing first — we don't decide for you, we give you the math and the recommendation.
Why heaters fail early in South Florida (and how we stop it)
The most expensive heater failures here aren't worn-out parts — they're wrong sizing and bad plumbing baked in at install. A diverter valve run closed, or a 3-inch line forcing too much water through a heater rated for ~70 GPM, swells and blows the heat exchanger and can take the pump with it. We've seen that one mistake cost a homeowner roughly $10,000. So we check the diverter and the heater's sizing against your actual flow on every visit.
The other silent killer is water chemistry. Balanced water lets a heater run 20–30 years; acidic water etches the heat exchanger and high calcium scales it shut, and either one can mean a new heater every 2–3 years. Keeping your chemistry in range is the cheapest heater insurance there is — and it's exactly what our weekly service is built to do.
Heater Repair — Common Questions
It depends on the failure. We diagnose first and quote in writing before any parts are ordered. A small fix — a flow problem from a dirty filter, a sensor, an igniter — is inexpensive. Major component replacement is where the math changes: a new heat exchanger or compressor typically runs $4,000–$5,000, and a full new heater runs about $5,000–$7,000. When the repair gets that close to a replacement, we'll tell you honestly that a new, more efficient unit is the better spend.
