Our Pool Heater Repair in Oakville, Burlington, Hamilton, and the Surrounding Areas
Our pool heater repair services in Oakville, Burlington, Hamilton, and the surrounding areas include ignition testing, safety system checks, burner and control diagnostics, and targeted repairs based on the technician’s findings. We work with natural gas and propane pool heaters and carry parts for commonly used residential models.
Ignition Problems
If your pool heater fails to light or shuts down soon after starting, the issue may be with the pilot assembly, flame sensor, or ignition control. Our technicians complete a full ignition system test and clean or replace worn components as required.
- Pilot and burner assembly are inspected
- Flame sensor response is tested and cleaned
- Electrical connections are checked for continuity
- Gas flow and pressure are verified
- Ignition delay or misfire is corrected
Temperature Control or Thermostat Failures
Inconsistent heating or poor response to thermostat settings can indicate a faulty control board or temperature sensor. We assess the control system's electrical and mechanical operation to determine what needs repair.
- Thermostat function is verified and adjusted
- Temperature sensors are inspected and tested
- Control board status is checked for signal response
- Heater response to commands is monitored
- Any necessary part replacements are discussed with the customer
Burner and Orifice Blockages
Spiders, debris, or rust in the burner or orifices can prevent proper gas flow. We inspect and clean the affected areas using compressed air and manufacturer-approved tools to restore clean flame output.
- Burner ports are cleaned and realigned
- Orifices are inspected for blockages
- Pilot flame is adjusted if necessary
- Debris is cleared from combustion chamber
- Burner is tested under normal operation
Pressure Switch or Flow Sensor Issues
The heater will not operate if it detects inadequate water flow. We test the pressure switch and flow sensors to confirm safe operating conditions and repair or replace components that are malfunctioning.
- Water flow is tested through system
- Pressure switch is inspected for continuity
- Sensor readings are confirmed with multimeter
- Any wiring or tubing damage is repaired
- Heater is tested after replacement to verify result
System Safety Shutdowns
If your heater shuts down for safety reasons, we perform a full control circuit test to identify the cause. This includes testing the ON/OFF circuit, rollout switches, and exhaust safety devices.
- Rollout switches are tested for response
- Exhaust system is checked for blockages
- Control circuit continuity is verified
- ON/OFF switch sequence is tested
- Findings are reviewed with the customer before proceeding
Why We Don’t Automatically Inspect the Heat Exchanger
We do not inspect the heat exchanger unless there’s a clear reason to do so. This approach is based on both time and cost considerations. Accessing the heat exchanger can take 60 to 90 minutes or longer, which adds significantly to the overall service cost. In most cases, a heat exchanger does not need to be opened unless the technician identifies symptoms that point directly to a problem in that area. By focusing on the issue at hand, we avoid unnecessary labour charges and keep service efficient. If inspection is required, the technician will explain the reason and provide a quote before continuing.
Signs Your Pool Heater Needs a Service Call
A gas pool heater should start consistently, heat the water efficiently, and shut off without errors. If it doesn’t, it may be time to schedule a service call. Ignoring minor issues can lead to more serious problems, increased fuel usage, or complete system failure. A quick diagnostic visit can often prevent costly repairs or downtime during peak swimming months.
Here are common signs your pool heater needs attention:
- The heater won’t ignite or turns off shortly after starting
- Water takes too long to heat or doesn’t reach the set temperature
- Pilot light won’t stay lit or fails to ignite
- Strange noises during operation, such as clicking, buzzing, or whistling
- Error codes displayed on the control panel
- Visible soot or burn marks on the exterior or around the burner
- Heater runs constantly without maintaining water temperature
If you notice any of these issues, book a service call to address the problem early and keep your pool heater running safely and reliably.
