How much does furnace installation cost in Orange County?
A 95% AFUE high-efficiency gas furnace installed in Orange County typically costs $4,500 to $7,000 including permit, HERS testing, and Southern California Gas coordination. Variable-speed premium furnaces run $5,500 to $9,000. All-electric furnaces run $3,000 to $5,500.
How long does furnace installation take?
Most furnace replacements take 4 to 6 hours of on-site work and can be completed same-day. Full new installations with new ductwork or gas line modifications take 1 to 2 days. Permit and HERS testing add 1 to 2 weeks to total project timeline.
Do I need a permit to replace my furnace?
Yes. Every Orange County city requires a building permit and HERS testing for furnace replacement under California Title 24. Aerosphere pulls the permit, schedules HERS testing, and coordinates city inspection. DIY furnace work is illegal and voids homeowners insurance.
Should I replace my furnace with a heat pump instead?
For most Orange County homes, yes. Heat pumps replace BOTH AC and furnace with one efficient electric unit and qualify for $2,000-$8,000 in federal IRA rebates plus SCE rebates. Heat pumps work well in OC because winters rarely drop below freezing. Aerosphere helps you calculate the rebate-adjusted comparison.
