Our licensed technicians diagnose the problem quickly and provide upfront pricing before any work begins.

Whether you need a simple thermostat adjustment, a full tank replacement, or a new tankless water heater installation, we have the experience and parts to get your hot water back the same day. Call us at (416) 555-0199 for immediate assistance or a free quote.

Types of Water Heaters We Service

Our team is trained and equipped to work on every major type of residential and commercial water heater available in Toronto.

  • Tank water heaters — Traditional storage tank models in 40, 50, and 60-gallon capacities. Gas and electric models serviced and installed.
  • Tankless water heaters — On-demand units that heat water only when you need it, providing endless hot water and lower energy bills. We install and repair all major tankless brands.
  • Hybrid heat pump water heaters — Energy-efficient units that use heat pump technology to reduce electricity consumption by up to 60 percent compared to standard electric tanks.
  • Power vent and direct vent water heaters — Specialized venting configurations for homes where conventional atmospheric venting is not possible.
  • Commercial water heaters — High-capacity units for restaurants, apartment buildings, and commercial properties.

Signs Your Water Heater Needs Service

Catching problems early can save you from a cold surprise or a flooded basement. Contact us if you notice any of the following warning signs:

  • Inconsistent water temperature or complete loss of hot water
  • Unusual noises such as rumbling, popping, or banging from the tank
  • Rusty, brown, or discoloured water from hot water taps
  • Visible leaks, drips, or pooling water around the base of the unit
  • A noticeable increase in your gas or electricity bills
  • The water heater is more than 10 years old (tank) or 20 years old (tankless)
  • Frequent pilot light outages or error codes on tankless displays

Repair vs. Replace: Making the Right Decision

Not every water heater problem requires a full replacement. Minor issues like a faulty thermostat, a worn anode rod, or a broken heating element can often be repaired affordably and quickly. However, replacement is usually the better investment when the unit is nearing the end of its expected lifespan, when repair costs exceed 50 percent of the price of a new unit, or when the tank shows signs of internal corrosion such as rusty water or visible rust on the tank body.

Our technicians provide honest, straightforward advice. We will never recommend a replacement when a repair will do, and we will never patch a unit that is on its last legs. You get a clear explanation of your options and a written quote for each so you can decide with confidence.

Brands We Service and Install

We work with all major water heater brands available in Canada, including Rheem, A.O. Smith, Bradford White, Rinnai, Navien, Noritz, Giant, John Wood, and GSW. Whether your unit is under warranty or decades old, our technicians have the parts and expertise to service it.

Frequently Asked Questions

How much does water heater repair cost in Toronto?

Water heater repair costs in Toronto typically range from $200 to $600 depending on the type of unit, the nature of the problem, and the parts required. A full tank water heater replacement usually costs between $1,200 and $2,500 installed, while tankless units range from $2,500 to $5,000. We provide a free, upfront quote before starting any work. Call (416) 555-0199 for a free estimate.

What is the difference between a tank and tankless water heater?

A tank water heater stores and continuously heats a reservoir of water (typically 40 to 60 gallons), so hot water is always ready. A tankless water heater heats water on demand as it flows through the unit, providing an endless supply but at a limited flow rate. Tankless units are more energy-efficient and last longer (20+ years vs. 10 to 15 years), but they cost more upfront. Our technicians can help you decide which type is best for your household needs and budget.

What are the signs my water heater needs to be repaired or replaced?

Common warning signs include inconsistent or no hot water, unusual noises such as rumbling or popping from the tank, rusty or discoloured water from hot taps, visible leaks or pooling water around the base of the unit, a sudden increase in energy bills, and the unit being over 10 years old. If you notice any of these signs, call us at (416) 555-0199 for a professional inspection before a small issue turns into an emergency.
