Common Water Heater Repairs – We Fix Them All!

Like any household appliance you use on a daily basis, your water heater will eventually need service, routine, maintenance or repairs. Here’s a look at some common issues that often require professional service.


  • Water temperature issues. A faulty thermostat, worn-out heating element or temporary power outage can cause your water heater to stop working. Before calling a professional, ensure the breaker isn’t tripped. Additionally, make sure the furnace disconnect switch isn’t turned on.

    If your water is too hot, your thermostat may be set too high. We recommend setting your water heater to 49 C or 120 F.

    If your water is warm but not hot, your water heater may be too small for your needs. Alternately, you may have crossed the hot and cold connections. Turn the water heater off and run a hot water tap. If it flows, you have a crossed connection.

  • Water heater leaks. Several things can cause a water heater leak, including a faulty pressure release valve, excessive water pressure, loose element bolts or a bad pipe connection. First, ensure the leak isn’t coming from somewhere else, like your basement foundation or another nearby pipe.

  • Discoloured water. If your hot water is brown or contains sediment, the inside of your water tank may be corroded. This could be caused by an old anode rod. A Harmony Heating & Air Conditioning Inc. technician can help you get to the root of the problem.

  • Strange noises. Sediment buildup on the bottom of your water heater can cause your tank to make strange noises. Flushing your tank can often solve the issue.

Tankless Water Heater Repairs And Maintenance

Tankless water heater systems have unique upkeep needs that our technicians know how to address.

Mineral Buildup
This issue can happen when your home or business has hard water. The buildup of minerals, such as calcium, can decrease the unit’s efficiency. The Harmony Heating & Air Conditioning Inc. experts can address this concern.
Typically, tankless water heaters experience less corrosion than standard units. However, because of the delicate computer sensors, even a small amount of corrosion can trigger a warning light or cause the system to shut down. Our crew can provide regular servicing to be sure this doesn’t occur.
System Overload
If two high-demand appliances run simultaneously, the water heater’s computer may be unable to keep up with the hot water demand. If this happens, it’ll shut down. Harmony Heating & Air Conditioning Inc. can expand your natural gas line to help address this problem.

Additionally, our team can install a separate water heater for a high-demand appliance to take the burden off the home’s overall system.
