AC changeout permits in Long Beach, CA

General California guidance last updated October 12, 2026 · Long Beach data fully re-verified

What HVAC contractors need to know about pulling a ac changeout permit in Long Beach (Los Angeles County).

Short answer

In California, an AC changeout (also called an HVAC changeout) — replacing a central air conditioning condenser, coil, or furnace — needs a mechanical permit (and often electrical for the condenser circuit), pulled by a licensed C-20 contractor. The work is governed by the California Mechanical Code (Title 24, Part 4) and the California Energy Code (Title 24, Part 6), and most residential replacements require third-party HERS testing for duct leakage and refrigerant-charge verification.

Long Beach accepts submittal through the LB Services — Permitting and Licensing and has adopted the 2025 California Building Standards Code (with the Long Beach Municipal Code). Fee details and sources are below.

The general picture in California

An HVAC changeout (also written A/C change-out) is permitted mechanical work in nearly every California jurisdiction. California's Title 24 Part 6 energy standards require third-party HERS verification on most residential AC and furnace replacements — typically duct-leakage testing, refrigerant-charge verification, and airflow when ducts are altered. Replacements may also require updating combustion air, condensate drainage, condenser disconnects and clearances, and a smart thermostat under some prescriptive packages. Heat-pump replacements add electrical-load and circuit considerations.

Code basis

2025 California Building Standards Code (Title 24), which applies to permit applications filed on or after per the California Building Standards Commission. Sections checked against the published code; cities may add local amendments.

  • California Mechanical Code (Title 24, Part 4) §104.1 — Permits Required: a mechanical permit before installing, altering, repairing, replacing or remodeling a mechanical system; §104.2 (Exempt Work) covers only portable appliances and like-for-like component replacement that does not alter the appliance's approval.

  • California Mechanical Code (Title 24, Part 4) §1104.6 — Group A2L Refrigerants for Human Comfort: listing and installation requirements (§1104.6.2) and mechanical ventilation (§1104.6.4) for the R-454B and R-32 systems replacing R-410A.

  • California Energy Code (Title 24, Part 6) §150.2(b)1E / §150.2(b)1F — Replacing the condenser, air handler or coil is an alteration: §150.2(b)1E requires sealing the connected ducts with field verification and diagnostic testing, and §150.2(b)1F requires setback thermostats plus refrigerant-charge verification for air conditioners in Climate Zones 2 and 8 through 15 and for heat pumps in every climate zone.

Typically needs a permit

AC changeout itself triggers a permit in nearly every California jurisdiction, Long Beach included. Long Beach-specific variations are confirmed with the issuing department above.

Usually doesn't (general norm)

  • Replacing a thermostat with a like-for-like (non-smart) unit
  • Replacing a capacitor, contactor, or fan motor on the existing condenser (repair, not replacement)
  • Cleaning coils, replacing filters, or relighting the pilot

Common reasons ac changeout applications get bounced

Code-rooted patterns across California — not a Long Beach-specific rejection rate.

The inspection sequence

A typical order — the number of stops and exact sequence vary by jurisdiction and scope.

  1. 1Rough/in-progress not typically required for like-for-like equipment swaps
  2. 2HERS verification (third-party rater) for duct leakage and refrigerant charge as applicable
  3. 3Final inspection with the equipment installed, energized, and tested; HERS certificates filed

Licensing — who can pull it

HVAC changeouts in California are generally performed by a C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) licensed contractor; a B (General Building) contractor may pull within a larger project under CSLB rules. The licensed contractor doing the work typically pulls the permit.

Frequently asked questions

Do I need a permit for a like-for-like AC changeout in California?

Generally yes. Even a like-for-like air conditioning changeout — a straight condenser or furnace swap — triggers a mechanical permit and Title 24 Part 6 compliance (HERS testing for duct leakage and refrigerant charge) in nearly every California city. Repairs to existing equipment generally don't.

What is HERS verification and why is it required?

Title 24 Part 6 requires third-party HERS (Home Energy Rating System) raters to verify specific measures on residential replacements — most commonly duct leakage and refrigerant charge. The rater's CF2R/CF3R certificates are filed with the permit; missing HERS documentation is a top reason for rejection or failed final.

Do I need an electrical permit too?

If the condenser circuit, disconnect, or breaker is replaced or upsized, yes — that's electrical work. Most jurisdictions bundle it under the mechanical permit but require electrical scope on the application. Heat-pump conversions almost always need an electrical permit.

How does the A2L refrigerant transition affect permits?

New systems shipped after the EPA's 2025 A2L transition use mildly-flammable refrigerants (R-454B, R-32) requiring listed line sets, leak-detection where applicable, and updated installation practices. The application and cut sheets should reflect the refrigerant type; some jurisdictions are still updating their checklists.
