What drives HVAC replacement costs in Long Beach
System size, ductwork condition, and whether your home already has central air ducts are the biggest cost factors for a full replacement.
Older bungalow homes in California Heights and Bixby Knolls without existing ductwork typically cost more to convert to central air than homes that just need equipment swapped.
Los Angeles County labor rates run somewhat higher than statewide averages, which is reflected in the ranges below.
Ducted system replacement pricing
A full ducted AC and furnace replacement in a home with existing, functional ductwork typically falls in the $8,500-$16,000 range depending on equipment tier and efficiency rating.
If ductwork needs repair or replacement as part of the job, budget an additional $2,000-$7,000 depending on how extensive the attic or crawlspace work is.
Higher-efficiency equipment costs more upfront but may qualify for utility rebates, which can offset some of the difference.
Ductless mini-split alternative
For homes without existing ducts, a ductless mini-split system is often more cost-effective than adding full ductwork, typically running $3,500-$6,500 per zone.
Multi-zone systems let you cool bedrooms and living areas independently, which is popular in Long Beach's smaller bungalow floor plans.
Ask your contractor to compare total mini-split cost against a full ducted retrofit before deciding, since the right choice depends heavily on your home's layout.
Permits, Title 24, and HERS testing
Most replacements in Long Beach city limits go through the City's Building and Safety Bureau, and many like-for-like changeouts qualify for the Express Mechanical Permit that skips plan review.
Title 24 energy code compliance may require a certified HERS rater to verify duct leakage and airflow after installation, particularly on larger or ducted system replacements.
Homes in the Coastal Zone or Historic Districts, including parts of Belmont Shore and Naples, are typically excluded from the express permit path and need standard plan review instead.
See our Long Beach HVAC hub for more on the permit process and licensing requirements.
Rebates that can lower your total cost
Southern California Edison offers incentives through TECH Clean California for qualifying heat pump HVAC systems, including up to $2,000 for two systems in a single-family home.
SoCalGas offers furnace rebates, but requires proof of permit closure with the city before releasing payment, so keep your permit paperwork on hand.
