What Coquitlam Homeowners Say
"No hot water on a Tuesday morning. Called HVAC Coquitlam, plumber arrived within 3 hours, replaced the thermocouple, and hot water was back before noon. Fast and affordable."
"Our Navien tankless was throwing error codes. They diagnosed it quickly — dirty heat exchanger — cleaned it out and it's been running perfectly for 6 months. They knew exactly what they were doing."
"They honestly told me my 11-year-old tank wasn't worth repairing. Showed me the corrosion on the anode rod and the sediment buildup. I appreciated the honesty. Installed a new one the next day."
Water Heater Repair FAQs
Why is my hot water not working?
For gas water heaters, the most common causes are a failed thermocouple or thermopile (pilot won't stay lit), a faulty gas valve, or a failed ignitor. For electric heaters, the most common cause is a burned-out heating element or faulty thermostat. For tankless units, it's usually a component failure or error code — often related to ignition, flame sensor, or heat exchanger.
How long should a water heater produce hot water?
A 40-gallon tank provides 30–45 minutes of continuous hot water for a typical household. If hot water runs out much faster than usual, sediment buildup or a failed element is likely. If you have a tankless unit that's cutting out, it may be overloaded or have a component issue.
Should I repair or replace my water heater?
Repair makes sense if the unit is under 7–8 years old and the repair cost is less than 50% of replacement cost. If your tank is over 10 years old, corroding, or has had multiple repairs, replacement is usually more economical. We'll give you an honest assessment after diagnostics.
Can you repair a tankless water heater?
Yes. We diagnose and repair all major tankless brands including Navien, Rinnai, Noritz, Bosch, and Rheem. Tankless repairs often involve cleaning heat exchangers, replacing ignition components, or addressing flow sensor issues. Error code diagnostics are included in our service call.
What causes no hot water in a Coquitlam home?
For gas heaters, it's most often a thermocouple failure (pilot light related) or ignitor issue. For electric heaters, it's usually a heating element. For all types, sediment buildup from our local water supply can reduce efficiency significantly over time — an annual flush helps prevent this.
