We've diagnosed and repaired every type of heater failure a home can throw at us. Here are the problems our clients call us about most often.
A furnace that won't start at all usually has a failed igniter, a tripped safety switch, or a control board fault. In older units, a faulty thermocouple or standing pilot issue is often the cause. Running repeated restart cycles when the unit fails to fire can mask the real problem and delay the correct repair. We test the ignition system, safety switches, and control circuit to find the exact fault and fix it.
A heater that turns on, runs briefly, then shuts off before reaching the set temperature is short-cycling. This puts repeated stress on the ignition system and heat exchanger and usually gets worse over time. Common causes include a clogged filter, a failing pressure switch, a tripping high-limit switch, or a cracked heat exchanger. We test each possible cause in sequence before making any repairs.
A pilot that goes out repeatedly is almost always a thermocouple problem. The thermocouple senses pilot flame and holds the gas valve open. When it weakens or fails, the valve closes and the pilot goes out. Relighting it repeatedly without replacing the thermocouple leads to the same result every time. We test the thermocouple output, inspect the pilot assembly, and replace the faulty component.
A heater running but not producing adequate heat usually has a dirty or restricted burner, a failing heat exchanger, a blocked flue, or a gas supply pressure issue. Running at reduced output for extended periods can accelerate wear on other components. We measure heat output, check gas pressure at the unit, inspect the burner and heat exchanger, and identify exactly why the heater is underperforming.
A boiler that repeatedly loses pressure has a leak somewhere in the system, a failing expansion tank, or a faulty pressure relief valve. Simply re-pressurizing the system without finding the source leads to the same loss within days. We pressure-test the system, inspect the expansion tank, check all visible connections, and trace the pressure drop to its actual source before making any repairs.
A pool heater that runs through its cycle without warming the water usually has a heat exchanger blockage, a burner not firing at full capacity, or a low gas pressure condition at the unit. Continuing to run the heater in this state can damage internal components further. We inspect the burner, test gas pressure, and assess the heat exchanger to find the cause and restore proper heating performance.
Fault codes on a tankless heater point to a specific failure: low water flow, a blocked inlet filter, mineral scale buildup in the heat exchanger, or a failing flow sensor. Each code has a defined meaning, and addressing it correctly requires identifying the component causing it rather than resetting and hoping. We read the fault, trace it to the source, and resolve it through cleaning, descaling, or part replacement.
Banging during startup often means delayed ignition from a dirty or misaligned burner. Rumbling from a boiler usually points to sediment buildup in the heat exchanger. Clicking without ignition suggests a faulty spark igniter. Each sound has a specific cause, and chasing noise with adjustments rather than diagnosis rarely solves it. We inspect the component producing the sound and repair the actual fault.
A healthy gas heater flame should burn blue and steady. A yellow, orange, or flickering flame indicates incomplete combustion, which produces elevated carbon monoxide and reduces heating efficiency. This is a safety concern that should be addressed before the heater is used again. We clean the burner, verify combustion air supply, and check gas pressure to restore a correct, stable flame.
Our furnace kept shutting off right after starting and I assumed it was something major. The technician from Gas Services Edmonton cleaned the flame sensor and it's run perfectly since. Wish I had called sooner instead of putting up with it for weeks.
Furnace died overnight right as temperatures dropped. Called first thing in the morning and had a technician out by early afternoon who diagnosed a failed ignitor and had heat restored within the hour.
The control board on our older furnace needed to be special-ordered so we waited a few days longer than expected. Communication was clear throughout though and the furnace has run without issue since the repair.
I was fully expecting to hear I needed a new furnace given its age. Gas Services Edmonton explained the actual repair was a straightforward blower motor fix and saved us thousands compared to what I was bracing for.
Called Gas Services Edmonton about a noisy blower and the technician also found the heat exchanger was starting to show hairline cracking during his safety check. Glad he checked beyond the original complaint.
The technician explained exactly what was wrong and gave me a firm price before touching anything. No surprises on the final bill, and the furnace has been reliable since the repair.
