With proper maintenance, tankless water heaters can last over 20 years. But when issues arise, prompt water heater repair in Airdrie or Calgary can prevent further damage and restore hot water quickly.

Here are the most common issues we fix:

No Hot Water: If your unit receives gas or electricity but still fails to produce hot water, the issue may involve ignition, venting, burners, or electronics.

Low Water Pressure: This could result from blocked pipes or insufficient unit capacity. We may recommend an upgrade or a second tankless unit to meet your household’s hot water needs.

Inconsistent Water Temperature: Temperature fluctuations often result from pipe obstructions, water pressure issues, or crossover problems.

Loud Noises: Unusual sounds can signal debris inside the unit or fan/gas combustion issues.

Mineral/Sediment Buildup: Hard water in Calgary and Airdrie (due to calcium and magnesium) can cause buildup. We recommend annual water heater flushing to prevent long-term issues.

Overload or System Shutdown: Tankless water heaters can shut down when overloaded. We can assess your household’s usage and suggest higher-capacity models or multiple units.

Ignition & Flame Failures: Flame and ignition issues often point to problems with gas pressure or faulty electronic components.
