Direct answer
What should you do when the water heater stops working?
If water is actively leaking, keep clear of standing water near electrical equipment and shut off the unit or water supply only if you can do so safely. Note whether the problem affects all hot-water fixtures, then request an evaluation. The unit type, failure, condition, and installation determine the next step.
When to evaluate
Water heater problems Mesa can evaluate
Symptoms provide useful clues, but the unit still needs to be checked before repair or replacement is recommended.
Water around the unit
A connection, valve, component, or the tank itself may be leaking. Avoid contact with nearby electrical equipment.
Temperature changes
Water that is too hot, not hot enough, or inconsistent can point to a control, heating, mixing, or capacity issue.
Noise, odor, or error codes
Record when the symptom happens and any code displayed so the diagnostic visit starts with better context.
Service process
A repair or replacement decision based on the unit
Mesa evaluates the equipment before recommending work, rather than assuming every loss of hot water needs a new system.
Document the symptom
Share the unit type, visible model information, when the problem started, and whether water is leaking.
Inspect the system
The evaluation considers the unit, connections, controls, installation, and the symptom being reported.
Review the options
Mesa explains the observed issue and whether repair, maintenance, or replacement deserves consideration.
Complete the selected work
After the homeowner approves the work, the selected service can be completed and the system checked.
Choose by condition
Repair, replace, or consider tankless?
The right path depends on the failed component, equipment condition, household demand, available utilities, and installation requirements.
Request an EvaluationWater heater repair

Water heater replacement
May deserve consideration when the tank has failed, problems keep returning, or the equipment condition makes repair impractical.
Tankless evaluation
May fit homeowners comparing a different system type, but sizing, fuel, venting, electrical needs, and installation all matter.

Frequently asked
Water Heater Repair questions.
Direct answers for Boulder-area homeowners comparing the next step.
Why is my water heater not producing hot water?
Power, fuel supply, ignition, heating elements, controls, safety devices, or another unit condition may be involved. An evaluation is needed to identify the cause.
Does a leaking water heater always need replacement?
Not every leak comes from the tank. Connections, valves, or components can leak too. If the tank itself has failed, replacement may be necessary, but the source should be confirmed.
Should I repair or replace my water heater?
The decision depends on the failed part, unit condition, repair history, efficiency goals, and installation requirements. Mesa evaluates the equipment before explaining the available paths.
Can Mesa evaluate tank and tankless water heaters?
Mesa can evaluate water-heater symptoms and the system type at the property, then explain which service or replacement path fits the observed condition.
What should I include in a water heater service request?
Share the service address, unit type if known, the main symptom, when it started, whether water is leaking, and any code displayed by the equipment.
Start with the actual equipment condition.
