Boiler Repair and Troubleshooting: Expert Diagnostics for Residential Hydronic and Radiant Heating Systems
Heating failing? Pilot light out? Call Jessy for fast, reliable boiler service in Surrey, Vancouver, Langley, Delta and the surrounding areas.
In the Lower Mainland, a functional boiler is the heart of your home’s comfort, especially for those with radiant in-floor heating or traditional baseboard radiators. Unlike standard furnaces, boilers are complex pressurized systems that require a specialized touch. At Jessy Plumbing & Heating, we provide comprehensive boiler repair and troubleshooting services, including expert Boiler Repair and Troubleshooting services across Vancouver and Surrey. As Red Seal certified professionals, we understand the intricate relationship between water pressure, gas flow, and electrical controls, ensuring your system is restored to peak efficiency and safety.
Common Boiler “Red Flags”
When to Call for a Professional
Low System Pressure: If your pressure gauge is dropping, you likely have a leak or a failing expansion tank.
Pilot Light Issues: A flame that constantly goes out or burns yellow instead of blue indicates a combustion problem.
No Heat or Hot Water: Often a sign of a failed motorized valve, a broken diaphragm, or a faulty thermostat.
Cold Spots in Radiators: This usually indicates trapped air or a sludge buildup in the hydronic lines.
Our Diagnostic Approach
We don’t just swap parts; we find the “why” behind the failure. Our troubleshooting process involves checking the circulator pump, testing the manifold valves, and ensuring the heat exchanger is free of cracks. By taking a holistic view of your hydronic system, we prevent minor issues from turning into a complete system breakdown during the coldest months of the year.
Helpful Tips: Before calling for service, double-check your thermostat settings. It sounds simple, but many “no heat” calls are solved by simply replacing the batteries or ensuring the system is set to “Heat” rather than “Auto.” If your thermostat screen is blank or the boiler doesn’t click on when you raise the temp, it may be a low-voltage electrical issue. If everything looks right and you’re still cold, call an expert for a diagnosis.
The Core Components We Service
Circulator Pumps
The pump is responsible for moving hot water through your pipes. If it’s stuck or noisy, your radiators will stay cold. We repair and replace high-efficiency pumps to keep your water moving.
Expansion Tanks
These tanks manage the pressure as water heats and expands. If your boiler is leaking from the relief valve, your expansion tank is likely “waterlogged” and needs service.
Zone Valves & Controls
Modern boilers use zone valves to heat specific rooms. We troubleshoot the electrical actuators and manifold connections to ensure every corner of your home gets the heat it needs.
