Signs Your Water Heater Needs Service
No Hot Water or Insufficient Heat
Running out of hot water quickly or no hot water at all indicates a failing heating element, thermostat, or sediment buildup in your tank.
Leaking Water Around the Unit
Any pooling water around your water heater is a serious issue requiring immediate attention to prevent water damage and potential emergency situations.
Rusty or Discolored Water
Rust-colored hot water indicates corrosion inside the tank. This often means the tank is deteriorating and replacement may be necessary soon.
Strange Noises (Popping, Rumbling)
Loud popping or rumbling sounds indicate sediment buildup at the bottom of your tank, reducing efficiency and potentially damaging the unit.
Age Over 10-12 Years
Water heaters typically last 10-15 years. If yours is approaching this age and showing issues, replacement is often more cost-effective than repair.
Rising Energy Bills
An inefficient water heater works harder and costs more to operate. Upgrading to a new energy-efficient model can save you money monthly.
