A practical starting point

No hot water, a leak or an error code?

Water heater repair in San Jose

No hot water, changing temperatures or water near the heater call for diagnosis before a repair is selected. Share when the problem began, which fixtures are affected and any safely readable model details. A visible leak or error code alone does not identify the failed part.

Tank water heater repair

Tankless water heater repair

Water heater replacement: compare the full scope

If replacement is recommended, ask what failed and how a repair would compare. Review the new equipment, removal of the old unit, access and any supporting work before choosing the next system.

Compare water heater replacement options

Water heater installation: match the home and demand

Describe the showers and appliances used together, the installation space and the existing fuel or electrical supply. The old tank's gallon rating is only one part of selecting a replacement.

Tank water heater installation and sizing

Tankless repair or a tankless conversion?

An existing tankless heater with an error code needs a different assessment from a home considering its first tankless system. Compare diagnosis with installation requirements, including simultaneous hot water use, supply and venting.

Considering a heat pump water heater?

Review air space, electrical compatibility, condensate drainage, sound and recovery before choosing equipment. If you already have a heat pump water heater, confirm model support and the available assessment scope before arranging service.

Review heat pump installation requirements

Before an assessment

What to have ready.

  • Exact error code, if safely visible
  • Leak location or loss-of-hot-water timing
  • Tank, tankless or heat pump model

Confirm service at the exact address and ask who verifies applicable permit and inspection requirements before work. No local exemption, utility incentive or appointment availability is promised here.

A question before you choose.

Does no hot water mean I need a new heater?

Not necessarily. A component fault, a supply issue or demand beyond the current system's capacity can require different work. Ask what the assessment found and compare the supported repair with replacement before deciding.
