A pool heater that won't fire or won't hold temperature is the fastest way to shorten a swim season. Our team in Stratford services natural gas, propane, and heat-pump pool heaters — Hayward, Jandy, Pentair, Raypak, Rheem, Sta-Rite — and carries the ignition, sensor, and gas-valve parts that account for most repairs.

Why pool heater repair matters in Stratford

Season-Length Matters

Every day the heater is down is a day of the swim season you don't get back. Fast turnaround is the whole point of a specialist service in Stratford.

Efficient Heating

A well-maintained heater burns cleanly, hits temperature faster, and costs less to run — especially with today's gas prices.

Safe Combustion

Pool heaters live outside, often exposed to weather and debris. Regular repair-side attention keeps ignition, venting, and gas trains working the way they should.

Our pool heater repair process

1
Full Diagnostic
We test ignition, flame sensing, pressure switches, water flow, and control-board fault codes before naming a repair.
2
Quote And Approval
You get a written quote before we replace anything — parts, labour, and total up front.
3
OEM Repair
Factory-quality parts, sized to your specific heater. No universal substitutes on the gas train.
4
Water Chemistry Note
Where relevant, we point out chemistry issues (low pH, high salt) that are quietly destroying your heat exchanger.
5
Startup And Verification
We bring the heater up to temperature, verify the run, and hand you a report.

Common findings in Stratford

Reliable across three jobs

Used them for a sweep, a dryer vent, and a fireplace service. Same standard every time and the same technician twice, which I appreciated.

Documentation on everything

Photos, readings, and a written summary after every visit. Makes it easy to keep records for the house file.

Had the chimney and the dryer vent done on the same visit. Cheaper and half the disruption.
