Water Heater Repair

Accurate diagnosis before we touch a wrench.

Whether it's a faulty thermocouple, a failing heating element, or a tankless unit throwing an error code, we diagnose the actual cause before we touch a wrench, so you're not paying for guesswork. We service all makes and models of tank and tankless systems.

Many repairs address symptoms without finding the underlying issue. We take the time to inspect and verify, so the fix lasts and you're not back on the phone a week later.

Water Heater Replacement

Sized to your household's real hot water demand.

We size your new system to your household's real hot water demand, not just a like-for-like swap. For tankless installs, that means calculating flow rate and temperature rise for your fixtures; for tank units, it means the right recovery rate for your family size.

Here's what most contractors won't tell you: a like-for-like replacement often doesn't account for changes in your household - more bathrooms, growing family, or new fixtures. We take the time to understand how your household actually uses hot water, so your new system keeps up without wasting energy heating water you don't need.

Water Heater Maintenance

Annual care that extends tank life and efficiency.

Annual flushing clears sediment buildup that shortens tank life and hurts efficiency, and gives us a chance to check anode rods, pressure relief valves, and venting before they become problems.

A well-maintained water heater uses less energy, recovers faster, and lasts longer. For tankless systems, regular descaling keeps the heat exchanger working at full capacity so you never notice a drop in performance.

Frequently Asked Questions

Water heater questions, answered.

Tank or tankless - which is right for me?

It depends on your household's hot water usage. Tankless systems provide endless hot water and save energy, but need proper sizing for flow rate and temperature rise. Tank units are simpler and have lower upfront cost. We'll help you weigh the options based on your actual demand.

How do you size a replacement water heater?

For tankless, we calculate flow rate and temperature rise based on your fixtures. For tank units, we determine the right recovery rate for your family size and usage patterns. We don't just do a like-for-like swap - we size to your actual needs.

What are the signs my water heater is failing?

Common signs include inconsistent water temperature, rusty or discoloured water, rumbling or popping noises from the tank, water pooling near the base, or a sudden drop in hot water capacity. If you notice any of these, give us a call.

How often should I flush my water heater?

We recommend an annual flush to clear sediment buildup. This extends tank life, maintains efficiency, and gives us a chance to inspect the anode rod, pressure relief valve, and venting before they become problems.

What brands do you service?

We service all makes and models of tank and tankless water heaters, including Carrier, Lennox, Trane, Ruud, and York.
