Gas Furnace to Heat Pump Conversion in Los Angeles: Cost, Panels & Ductwork

Last updated: September 2026

 

In Los Angeles, converting a ducted gas furnace to a heat pump typically costs between $8,500 and $15,000 before rebates, provided your ducts and electrical system are in good condition. If you need a panel upgrade (usually $2,500 to 5,500)or new ductwork (3,000 to $8,000 or more), the total cost can be much higher. The heat pump itself is just one part of the overall expense.

 

The $8,500 to $15,000 range is what we charge to install a ducted heat pump. The panel upgrade prices come from Los Angeles electricians and are not our rates. This guide is here to help you decide if a conversion makes sense before you get quotes. For more on whether a heat pump is right for you, see ‘Should I install a heat pump in LA.’

What Is a Gas Furnace to Heat Pump Conversion?

When you convert, your gas furnace and central AC are replaced with an electric heat pump that handles both heating and cooling. The outdoor condenser is swapped for a heat pump, the gas furnace is replaced with an indoor air handler, and the gas line is sealed off.

 

The job usually includes a new thermostat, refrigerant lines, a dedicated electrical circuit, and a permit.

 

Modern heat pumps use inverter-driven, variable-speed compressors and are rated by SEER2 for cooling and HSPF2 for heating. 

 

A properly designed heat pump system can provide both heating and cooling, but correct sizing, installation, and maintenance are essential for long-term performance. Learn more about our heat pump services in Los Angeles.

Real Price Breakdown: Heat Pump Conversion in Los Angeles

Costs are grouped into three levels based on the amount of work your electrical system and ductwork require.

Project TypeTypical Cost RangeWhat Changes the Price
Basic conversion (ducts and electrical adequate)$8,500 to $15,000 installed, before rebatesTonnage, SEER2/HSPF2 tier, variable-speed vs. single-stage, air handler, line set, thermostat, attic or rooftop access
Mid-range (minor electrical, some duct work)Upper part of the range above, plus $500 to $2,000 for duct sealing or localized repair where neededNew dedicated circuit and disconnect (should be itemized), new line set, duct modifications, permit scope
Full electrification (panel upgrade, major ducts)Add roughly $2,500 to $5,500 for a standard 100A-to-200A panel upgrade (market range) and $3,000 to $8,000 or more for full duct replacementService size, utility coordination, meter changes, panel location, duct layout, and insulation
Permits and testingCity of LA: Express mechanical permit commonly $120 to $300; independent rater commonly $150 to $350Separate electrical permit for new circuits or panel work; plan check for larger scopes. Confirm against the live LADBS fee schedule.
RebatesLADWP customers: $1,000 to $1,250 per ton (ducted)Eligibility, funding, equipment tier, and permit status. Never guaranteed

If you add up all the possible costs, a full electrification project can run from about $14,000 to $28,500 before rebates. This is just a rough calculation, not an official quote, and most homes only need some of these upgrades.

 

You can compare your estimate to the cost of replacing your AC and furnace in Los Angeles.

Does a Heat Pump Require a 200-Amp Panel Upgrade?

Not always. You only need a panel upgrade if your home’s total electrical demand requires it, not just because you are adding a heat pump. This is determined by a load calculation.

 

Who is more likely to need an upgrade:

  • Homes with older 60A, 100A, or 125A service, that are common in older Los Angeles homes
  • Homes already carrying large loads: electric range, dryer, EV charger, pool equipment.
  • Systems with electric resistance backup heat strips, which add substantial load (a 10 kW strip draws roughly 40 amps at 240 volts, as an illustration)

 

You may not need an upgrade if your home already has 200-amp service with extra capacity, or if you still use gas for your stove, dryer, or water heater.

 

Sometimes, using the right size equipment or load management devices can help you avoid a full upgrade. Always ask your electrician for a written load calculation.

200-Amp Panel Upgrade Cost

According to Los Angeles electricians, upgrading from a 100-amp to a 200-amp panel usually costs $2,500 to $5,500, including permits and inspection.

 

More complicated jobs, like moving the panel, underground service, or rebuilding the meter and service entrance, can cost $5,000 or much more. Here are the main factors that affect the price:

 

  • Main service replacement and new meter socket
  • Utility coordination with LADWP or SCE, which can add fees and scheduling time
  • Permits (LADBS inside the City of LA; other cities use their own building departments)
  • Trenching, rewiring, or wall and stucco repair
  • Hillside or tight-access locations

 

Ask your contractor who will handle the electrical work, permits, and warranties, and whether these costs are listed separately in your estimate.

Can Existing Furnace Ducts Handle a Heat Pump?

Often, yes—if your ducts are the right size, sealed well, and can deliver enough airflow for the new system. Your AC already uses these ducts for cooling, but in winter, a heat pump pushes cooler air than a gas furnace and at a higher volume.

 

Ducts are usually acceptable when they show:

  • Correct airflow capacity confirmed by static pressure testing
  • Adequately sized returns, since undersized return air is a common weak point
  • Supply registers that distribute the cooler heating air without drafts
  • Low leakage, ideally with duct sealing done alongside the swap

 

Under the 2025 California Energy Code, an altered duct system generally needs to be tested to 10% total leakage or less (or 7% to outside), and an entirely new duct system to 5% or less, verified by an independent rater. Older ducts, especially in attics with tight access, often require sealing and retesting. See the 2026 California HVAC regulations for the code context.

 

You will need to modify your ducts if they are crushed, disconnected, too small, or have old, damaged insulation. For our projects, sealing and small repairs usually cost $500 to $2,000, while full duct replacement is $3,000 to $8,000 or more. For details on how we check this, see our duct repair and replacement page.

Dual Fuel vs. Full Heat Pump Conversion

With dual-fuel, you keep your gas furnace as a backup, and the heat pump handles cooling and moderate heating. There is no one-size-fits-all answer—what works best depends on your furnace’s age, your electrical system, and your goals.

OptionCostBest ForLimitations
Dual fuelOften lower up front when the furnace has years left; controls add costNewer furnaces, limited electrical capacity, a gradual transitionStill depends on gas equipment, less electrification benefit, more complex controls, and a changeover setting to configure
Fully electric ducted heat pump$8,500 to $15,000 before rebates, plus electrical or duct work if neededFailing furnace and AC, adequate electrical service, electrification goalsMay trigger a panel upgrade or duct work; no gas backup
Ductless multi-split$7,000 to $15,000 multi-zone before rebatesHomes with poor or no ductsMultiple indoor units; LADWP's top rebate tier requires the system to serve the entire home

Heat Pump Rebates in Los Angeles: What Actually Applies

Your utility company decides which rebates you can get. LADWP rebates are only for LADWP electric customers, and not everyone in LA County is served by LADWP. If you have SCE or live in Ventura County (SCE and 3C-REN areas), you cannot use LADWP rebates.

Check ladwp.com and switchison.org for the latest program details before planning your budget.

 

Active, with limits:

  • LADWP Consumer Rebate Program: $1,000 to $1,250 per ton for central ducted heat pumps, and $1,500 to $2,500 per ton for qualifying ductless systems that serve the entire home. A 3-ton ducted system earns $3,000 to $3,750.

    Equipment must be purchased and installed on or after November 1, 2025, apply within 12 months, and be AHRI-matched with a final permit. Funding is limited, and ADUs and new construction are excluded.

  • South Coast AQMD GO ZERO: reopened single-family applications on August 28, 2026, with limited funding, for replacing gas or propane heating with a heat pump. Confirm current amounts and eligibility with South Coast AQMD.

 

Reserved or waitlisted: HEEHRA single-family funding has been fully reserved since early 2026, and TECH Clean California single-family heat pump incentives have been reserved since November 2025. A waitlisted HEEHRA project qualifies only if it is installed after reservation approval.

 

Expired: the federal Section 25C tax credit ended December 31, 2025.

 

Rebates lower your replacement costs after the work is done, but LADWP’s rebate only applies to the equipment, not the electrical work. Figure out your total project cost first, then check the rules for combining rebates across programs.

Why Los Angeles Homes Have Unique Conversion Challenges

  • Los Angeles is in Climate Zone 9 and has a long cooling season. In the San Fernando Valley, systems regularly run six to eight months each year, so your heat pump needs to be sized for both the hot August days and chilly January mornings.
  • The Valley gets both heat waves and cold snaps. Modern inverter heat pumps can keep your home warm even during the coldest nights, but it is important to get the sizing and defrost settings right.
  • Older housing stock: Older homes can combine small electrical services, undersized ducts, and limited returns.
  • Attic installations: Tight, hot attics complicate air handler placement, condensate routing, and duct access.
  • Rooftop equipment: Rooftop package units convert as packaged heat pumps, avoiding line sets but adding roof and crane access considerations.

Is Converting From Gas to Heat Pump Worth It?

It can be worth it, but no one should say that heat pumps are always cheaper. The right choice depends on your home’s electrical system, ductwork, equipment age, utility rates, and your goals. Your operating costs will depend on your electric and gas rates, so ask your contractor to compare costs using your actual utility bills, not just a general estimate.

Good candidates:

  • An aging furnace and a failing AC, so you are replacing both anyway.
  • Adequate electrical capacity
  • Ducts that test acceptably or need modest sealing
  • A goal of electrification, or an LADWP address that can capture rebates


Situations needing more evaluation:

  • A major panel upgrade is required.
  • The duct system is poor, or attic access is difficult.
  • The budget is limited, or the furnace is newer and working well (dual fuel may fit better)


Before you agree to any work,
ask for a Manual J load calculation, a written electrical load calculation, duct static pressure testing, an itemized estimate, permit and Title 24 details, and an AHRI-matched system with rebate paperwork.

Frequently Asked Questions

Q: How much does it cost to replace a gas furnace with a heat pump in Los Angeles?

A typical ducted conversion costs between $8,500 and $15,000 before rebates, provided your ducts and electrical system are in good shape. If you need a panel upgrade or new ductwork, it can cost thousands more. The final price depends on the system’s size, efficiency, ductwork, electrical work, and how easy it is to access everything.

Not always. Whether you need a 200-amp panel depends on a load calculation. Homes with older 60A, 100A, or 125A service are more likely to need an upgrade, which usually costs $2,500 to $5,500 according to Los Angeles electrician rates.

Often, if they are properly sized, sealed, and deliver the airflow the system needs, as confirmed by static pressure testing. Leaky, undersized, or deteriorated ducts may need sealing, repair, or replacement.

Dual fuel can cost less up front if your furnace still has years left, but that is not always the case. It also means you will need extra controls and will still rely on gas equipment. The best option depends on your furnace’s age, your electrical system, and your goals.

Yes. Modern inverter heat pumps can keep your home warm even when overnight temperatures drop in Los Angeles and the San Fernando Valley, as long as the system is sized correctly.

If you are an LADWP customer, you can get $1,000 to $1,250 per ton for qualifying ducted heat pumps and $1,500 to $2,500 per ton for ductless systems that serve your whole home. South Coast AQMD GO ZERO has reopened with limited funds. HEEHRA and TECH single-family funds are currently reserved, and the federal 25C tax credit has ended.

It depends on your electric rate plan, gas prices, your system’s efficiency, and your home’s insulation. Ask your contractor to compare running costs using your actual utility bills instead of a general estimate.
