Oakland HVAC · Service guide
Running out of hot water, a leak, or a replacement project needs its own assessment. A water heater provides domestic hot water and is not the same as a boiler serving radiators or baseboards.

Recognize the concern
These observations are a starting point, not a diagnosis. Tell the contractor what changed and when it happens.
Understand the scope
Share the equipment type, fuel or power source, location, and household hot-water needs. Ask whether the proposed service includes the specific water-heater type. Leave gas, electrical, and pressurized-water work to an appropriately qualified professional.
Confirm that the contractor handles your specific equipment and the work you need. Ask what the visit includes before scheduling.

Compare your options
Compare tank, tankless, and heat-pump options only where the site supports them. Installation can involve electrical capacity, fuel supply, ventilation, drainage, space, and maintenance needs. A compact unit or efficiency label alone does not establish the right fit.
Keep the written recommendation, included work, exclusions, and scheduling terms together. A clear scope is more useful than a promise made before the equipment is assessed.
It depends on the installation. Ask about fuel or electrical requirements, venting, piping, expected hot-water use, and all related work before deciding.
