Water heater replacement for Fresno homes
Most replacements are like-for-like: same fuel, same size, same spot. It's also the moment to check whether the old install was correct, because venting, gas line and expansion tank problems are common in older basements.

Water heater replacement in Fresno: what's different
Fresno's hard water and summer heat above 100°F shorten water heater life, especially in attics and garages. California requires seismic straps on every install.
Older Tower District and Fig Garden homes may need venting updates. Permits come from the City of Fresno's Development and Resource Management Department.
Hard groundwater leaves scale that cuts tank life, so annual flushing and a softener help. North Fresno homes from the 1970s and later are on their second or third heater, often in garages where a leak floods stored belongings. Adding an expansion tank and new shutoff valve is common.

No hot water? What to check first
On a gas water heater, check that the pilot is lit and the gas valve is on. On an electric heater, check the breaker and the high-limit reset button. If the pilot won't stay lit, the breaker trips again, or you smell gas, stop and call a plumber.
Costs & planning
Repair or replace your water heater?
Repair when a replaceable part failed on a heater under about 8 years old. Replace when the tank itself leaks, the heater is past 10 to 12 years, or repairs keep adding up. A leaking tank can't be repaired.
