Boiler Repair & Service in Fraser Valley

You notice your house feels cold, even when the thermostat is cranked up, or maybe some rooms are warm while others stay chilly. This often means the boiler is struggling to generate or distribute heat properly, possibly due to a faulty circulator pump, air trapped in the system, or a problem with the burner. Ignoring inconsistent heating won't make it better; it just means higher energy bills as your boiler overworks, and the underlying issue could damage other critical components.

If your boiler sounds like a kettle boiling, rocks tumbling, or you hear persistent banging and gurgling, that's not normal. Banging, often called "kettling," usually points to sediment buildup on the heat exchanger, causing water to overheat and steam bubbles to form. Gurgling generally indicates air trapped in the system. These noises aren't just annoying; they signal mechanical stress that reduces efficiency and speeds up wear and tear, potentially shortening your boiler's lifespan significantly.

Any sign of water, whether it's drips, puddles, or damp spots on the floor around your boiler, is a serious red flag. Leaks can come from a failing pressure relief valve, corroded pipes, a cracked casing, or issues with the circulator pump seal. Even a small leak can lead to extensive water damage, mold growth, and rust on vital boiler parts. A steady loss of water also means your boiler can't maintain proper operating pressure, leading to inefficiency and potential shutdowns.

If your pilot light keeps going out, or the boiler constantly cycles on and off without staying lit, you've got a problem. This typically points to an issue with the thermocouple (which senses the flame), a dirty pilot orifice, a faulty igniter, or problems with the gas supply. A boiler that won't stay lit or frequently shuts down is unreliable and inefficient, leaving you without consistent heat and hot water. Ignoring these issues can escalate into more serious ignition system failures or even gas supply safety concerns.

When your monthly heating costs are climbing steadily, but your comfort isn't improving, your boiler is likely the culprit. An unexpected jump in energy bills is a strong indicator that your boiler is losing efficiency. This could be due to sediment buildup, a failing circulator pump, a clogged burner, or general wear and tear that forces the unit to work harder to produce heat. An inefficient boiler is costing you money every day, and it signals that internal components are straining, which could lead to premature failure and costly replacements.

Minerals in your home's water, especially in areas with harder water common in parts of the Fraser Valley, can build up inside your boiler's heat exchanger and pipes over time. This sediment acts as an insulator, preventing efficient heat transfer and forcing your boiler to work harder. The solution often involves a professional power flush or chemical descaling of the boiler system to remove these deposits, sometimes combined with water treatment.

The circulator pump is the workhorse that moves heated water from your boiler through your radiators or baseboards and back again. If it wears out, seizes, or develops electrical problems, the water won't circulate properly, leading to cold spots or no heat at all. Our technicians will diagnose the pump's electrical connections and mechanical function, often requiring a repair, clearing of a blockage, or a full replacement to restore proper heat distribution.

Your thermostat is the brain of your heating system, sending signals to your boiler about when to turn on and off. An old, miscalibrated, or faulty thermostat, or issues with its wiring, can lead to incorrect signals, resulting in no heat, intermittent heating, or constant cycling. We will test the thermostat's functionality and wiring, or check other control components like zone valves or pressure switches, to determine if a simple recalibration, battery change, or a full replacement is needed.

Whether your boiler uses an old-school pilot light or a modern electronic igniter, the ignition system is critical for starting the burner. Blockages in the pilot orifice, a faulty thermocouple that doesn't sense the flame, a weak igniter, or issues with the gas valve can prevent your boiler from lighting up. Our licensed technicians will thoroughly inspect the entire ignition assembly, gas valve, and associated wiring. Cleaning, adjusting, or replacing specific ignition components is typically what's needed to get your boiler firing reliably.
