A pool heater that won't fire or won't hold temperature is the fastest way to shorten a swim season. Our team in Langstaff, Richmond Hill 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 Langstaff, Richmond Hill

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 Langstaff, Richmond Hill.

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. 1

    Full Diagnostic

    We test ignition, flame sensing, pressure switches, water flow, and control-board fault codes before naming a repair.

  2. 2

    Quote And Approval

    You get a written quote before we replace anything — parts, labour, and total up front.

  3. 3

    OEM Repair

    Factory-quality parts, sized to your specific heater. No universal substitutes on the gas train.

  4. 4

    Water Chemistry Note

    Where relevant, we point out chemistry issues (low pH, high salt) that are quietly destroying your heat exchanger.

  5. 5

    Startup And Verification

    We bring the heater up to temperature, verify the run, and hand you a report.

Common findings in Langstaff, Richmond Hill

  • Failed ignition control modules
  • Corroded heat exchangers on older units
  • Sooted burners from restricted airflow
  • Low water flow triggering pressure-switch shutoffs

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