The Fresno market

Fresno's Building and Safety booklet lists water heater and heating, ventilation and air conditioning work among its Level 1 example projects, reviewed within up to three business days. Fees, who may pull the permit, and inspection steps for these replacements were not confirmed, so check with the city before work begins. A related Fresno form notes that alterations requiring a permit and exceeding $1,000 in value trigger smoke and carbon monoxide alarm verification. DOE's Building America guide puts Fresno County in hot-dry climate zone 3B, where long summers make cooling the main load. Statewide, EIA's 2020 survey found 64% of California homes heat with natural gas and 54% have central air. California law requires all water heaters to be braced against earthquakes.

In Fresno's hot-dry climate, the furnace works far less than the AC, and about 62% of California homes heat with a furnace. When only the furnace has failed, a matched replacement is reasonable. When the AC is also aging, a heat pump can replace both. A furnace in the attic sits in serious heat all summer, so ask the contractor to check the flue and duct connections while they are up there.
