AC Installation and Replacement in Los Angeles

Whether your existing air conditioner has failed, uses R-22, or no longer keeps the house comfortable, or your home has never had central cooling, the right answer depends on the home: its cooling load, ducts, electrical capacity and permit path. This page explains what affects the price, the difference between a changeout and a full replacement, how we size and install systems, and which rebates apply in 2026. As a Los Angeles HVAC company, we also install heat pumps, ductless mini-splits and furnaces, so you can compare options with one team.

What affects AC installation cost in Los Angeles

AC installation and replacement prices depend on system type, tonnage, efficiency (SEER2), the indoor coil or air handler, ductwork, electrical scope, access, permits and required ECC field verification. A final price should be based on your home, not a generic online number.

Project type	Common planning range before rebates or financing
Central AC replacement	Often about $8,500–$17,500 depending on size, SEER2, indoor coil, permit and access.
Heat pump conversion	Often about $10,000–$22,000 depending on equipment, electrical, controls and rebate eligibility.
Ductless mini-split	Single-zone projects may start lower; multi-zone homes can move into full-system pricing.
Add-ons that change price	Duct repairs, new duct runs, panel upgrades, difficult attic access, crane work, required ECC field verification, zoning and high-efficiency variable-speed equipment.

These planning ranges are not a fixed HUS offer. Ask for each item in your proposal to be marked included, allowance, optional or excluded: equipment and controls, removal and disposal, refrigerant lines, ducts, drainage, electrical work, permits, testing, inspections and finish repairs. For a detailed breakdown, see the AC replacement cost guide for Los Angeles and AC installation cost factors. Financing may be available for qualified homeowners, subject to credit approval and program terms.

AC changeout vs full replacement vs new installation

A changeout replaces the outdoor condenser and the matched indoor coil or air handler while reusing ducts and other infrastructure that pass inspection. A proper changeout still includes load and equipment-match review, duct and return-air inspection, electrical and disconnect checks, condensate protection, permit responsibility, required ECC field verification, startup documentation and warranty registration. See the written changeout scope checklist.

A full replacement also addresses ducts, the furnace or air handler, refrigerant lines or electrical service when they are not suitable for the new equipment.

A new installation adds central cooling to a home that never had it, which is common in older Los Angeles homes with wall heaters or floor furnaces. It can involve new ductwork through the attic or crawlspace, an indoor air handler, refrigerant lines, condensate drainage and electrical work. Panel work depends on the load calculation and existing service; a 200-amp upgrade is not automatic.

Already have a furnace? A usable forced-air furnace can often stay while we add a compatible coil, outdoor unit, refrigerant lines, drainage, electrical work and controls, as long as the furnace blower, ducts and return air can support the cooling system.

Sizing, ducts and Manual J

We size systems with a Manual J load calculation, not by square footage alone. An undersized system runs constantly and struggles in heat waves; an oversized system short-cycles and leaves the house cold but clammy. The calculation accounts for:

Manual J factor	Effect on sizing
Square footage and layout	Volume to condition and how air moves between rooms.
Insulation	Attic and wall insulation change the cooling load.
Windows and sun exposure	West-facing and single-pane windows add solar heat gain.
Local climate	A 2,000 sq ft home in coastal Santa Monica needs a different system than the same home in Reseda.

Los Angeles microclimates matter. Coastal and Westside homes often need good dehumidification more than raw capacity, where variable-speed or multi-stage equipment helps. San Fernando and San Gabriel Valley homes need capacity for long, hot, dry stretches. See the Manual J load calculation guide and AC replacement sizing.

A high-efficiency unit cannot overcome leaky, crushed or uninsulated ducts. We inspect existing ducts and return air during the assessment. If ducts are torn, undersized, poorly insulated or leaking beyond applicable limits, we include duct repair or replacement in the scope. See common ductwork problems.

Electrical requirements

A new outdoor unit needs a correctly sized circuit and a service disconnect, and the panel needs capacity for the new load. Heat pump conversions and homes adding EV charging or other electric appliances may need a panel or load review. We identify this during the assessment so it appears in your written scope. See electrical panel and load review.

Permits and ECC field verification

AC and HVAC equipment changeouts in Los Angeles generally require a mechanical permit and inspection. The 2025 California Energy Code took effect January 1, 2026. Depending on the permitted scope, ECC field verification, formerly referred to as HERS testing, such as refrigerant charge, airflow or duct leakage testing, may be required before the permit is closed. Home Upgrade Specialist coordinates the permit and inspection steps for its installations, and your written scope states which permits and tests are included. See HVAC permit and ECC field verification scope.

What happens on installation day

• Home protection: the crew reviews the plan and protects floors and work areas.
• Removal: the old equipment is disconnected, and refrigerant and old equipment are handled according to applicable requirements.
• Installation: the outdoor unit is set on a level pad, the indoor coil or air handler is installed with fabricated sheet-metal connections, and new ductwork is connected where included.
• Pressure testing, evacuation and commissioning: refrigerant lines are brazed with nitrogen, pressure tested and evacuated before the system is charged, started, checked against manufacturer specifications and the thermostat is set up.
• Handoff: we walk you through the thermostat, filter size and replacement, basic troubleshooting, and manufacturer and labor warranty terms.

Timing depends on system type, access, electrical scope, ductwork, permits and inspection scheduling.

High-efficiency AC and heat pump options

Central air conditioners pair an outdoor condenser with an indoor coil, often on an existing gas furnace. Heat pumps cool in summer and heat in winter with one system, reduce gas use and can qualify for utility rebates; see heat pump installation in Los Angeles and heat pump vs central AC. Ductless mini-splits suit homes without a practical duct path, ADUs and additions. Package units house everything in one outdoor cabinet for homes without attic or closet space; see package unit systems. Variable-speed equipment with a higher SEER2 rating can reduce summer energy use, depending on the home, ducts and usage. Read more about energy-efficient AC installation in Los Angeles.

2026 rebates and tax credits

LADWP's Consumer Rebate Program covers qualifying heat pump HVAC systems. Its current application lists tiered rebates of $1,000–$1,250 per ton for qualifying ducted heat pumps and $1,500–$2,500 per ton for qualifying ductless systems, by efficiency tier. Key conditions include:

• The LADWP customer of record or verified property owner must sign and submit the application. If the applicant is not the customer of record, LADWP requires proof of ownership.
• For ductless mini-split and multi-split systems, the qualifying system must serve the entire home. Packaged Terminal Heat Pump units are not eligible.
• New construction and ADUs are not eligible.
• Equipment must be purchased and installed on or after November 1, 2025.

Example AC replacement scope

One published HUS planning scope uses a Goodman GLXS4BA4810A 4-ton R-32 condenser, CE60D3D-210R-165 cased coil and GR9S800804BUA 80,000-BTU Ultra-Low NOx furnace, with Manual J sizing, duct and return-air review, line-set evaluation, condensate protection, electrical review, permit responsibility, ECC field verification, startup checks and warranty documentation. It is a model-level scope example, not a claim that the same system fits every home. Review the Goodman 4-ton installation scope and Los Angeles HVAC project examples.

What to verify in any AC proposal

• Contractor: verify the business name, license status and C-20 classification with CSLB, and request insurance information.
• Matched equipment: outdoor unit, indoor coil or air handler, controller, capacity and match documentation.
• Installation scope: ducts, drainage, refrigerant lines, electrical work, access, removal and site-dependent work.
• Permit and closeout: permit responsibility, required testing, startup, inspection and handoff.
• Warranties and payments: manufacturer parts and contractor labor terms identified separately, plus a written payment schedule.

AC installation FAQ

How much does AC installation cost in Los Angeles?

Central AC replacement often runs about $8,500–$17,500 before rebates or financing, and heat pump conversions about $10,000–$22,000, depending on tonnage, SEER2, the indoor coil or air handler, ductwork, electrical work, access and permits. Compare bids on the same written, line-item scope. A precise number requires an in-home assessment.

Should I repair or replace my aging AC?

Compare the system's age, the failed part, refrigerant type and comfort problems against the cost of replacement. A system 10 to 15+ years old that uses R-22, needs a compressor or coil, or never keeps the house comfortable is usually worth comparing against replacement; a newer unit with a minor electrical fault is usually worth repairing. See AC repair vs AC replacement or schedule AC repair.

Can I add central AC to my existing furnace?

Often, yes, if the furnace blower can deliver the required airflow, the coil and outdoor unit are an approved match, and the ducts, return air, drainage, electrical circuit and controls are suitable. If the furnace itself needs work, see heater and furnace repair or furnace replacement.

Can I replace just the outdoor unit?

Pairing a new outdoor unit with an old, mismatched indoor coil usually causes efficiency, refrigerant-compatibility and warranty problems. Manufacturers generally require a matched indoor and outdoor combination.

Can an old R-22 line set be reused with new R-32 equipment?

It depends on the new equipment's installation requirements, tubing size, line length, condition, leak history and contamination risk. If reuse is proposed, the written scope should say how the line set will be evaluated, cleaned and tested, and what would trigger replacement.

Do I need to replace my ductwork?

Not always. Ducts that are torn, leaking, poorly insulated or undersized should be repaired or replaced, and depending on the permitted scope, duct leakage testing may be part of ECC field verification.

Do I need a permit to install AC in Los Angeles?

AC and HVAC equipment changeouts generally require a mechanical permit and inspection, and some projects require ECC field verification, formerly referred to as HERS testing. Your written scope should state permit responsibility.

Are there rebates or financing for a new AC system?

In LADWP territory, qualifying heat pumps list $1,000–$1,250 per ton for ducted systems and $1,500–$2,500 per ton for ductless systems, subject to program rules and funding. The federal 25C credit is not available for 2026 installations. Financing may be available for qualified homeowners. Confirm tax questions with a qualified tax professional.
