Commercial Water Heater Repair in DeKalb
Signs Your Water Heater Needs Repair or Replacement
Hot water plays a key role in daily operations for commercial facilities. When your water heater isn’t performing properly, it can disrupt day-to-day operations and impact your bottom line. If you're noticing delayed hot water, temperature swings, or rust-colored water, your system could be struggling. Other signs include leaks, strange noises, or increased energy bills. Ignoring these issues may lead to unplanned shutdowns or larger repairs later on. Regular inspections help maintain reliability and extend equipment life.
Water Heater Not Working?
Perhaps your taps are running lukewarm — or worse, cold. Maybe the temperature is sometimes just right, but other times too cool.
When there's a problem with your water heater, it's time to call the professionals.
Signs you need commercial water heater repair include:
- Lukewarm, inconsistent, or no hot water. Fluctuating or cool temperatures means it's time to call a specialist.
- Puddling or dripping water. Dripping or pooling around the water heater might mean a leak. Call a professional immediately to avoid water damage.
- Discolored water. Rusty water can indicate a corroded tank.
