Cooling for Los Angeles homes.

Los Angeles spans many microclimates, from mild Westside afternoons to 95°F–105°F valley heat. Older bungalows often have tight crawlspaces or no ducts, while valley ranches use attic or rooftop units.

## Climate

Los Angeles sits in IECC Climate Zone 3B and spans California Title 24 Zones 6, 8, 9, and 16. Basin neighborhoods (Culver City, Mid-City, Silver Lake) face increasingly hot late-summer Santa Ana wind events, while the San Fernando and San Gabriel valleys endure months of 95°F–105°F dry heat. Winters stay mild (lows in the 40s), which suits heat pumps.

## Local homes

Older LA neighborhoods (Hancock Park, Silver Lake, Echo Park, Santa Monica, Pasadena) feature 1920s–1950s bungalows and stucco homes with tight crawlspaces, low-clearance attics, or no central ductwork at all. San Fernando Valley and suburban communities (Sherman Oaks, Encino, Woodland Hills, Burbank, Glendale, Torrance) are dominated by single-story ranches and split-levels with horizontal attic furnaces or rooftop package units.

## Utilities

Los Angeles Department of Water and Power (LADWP) within the City of LA—or Southern California Edison (SCE), Burbank Water and Power, Pasadena Water and Power, and Glendale Water & Power in surrounding cities—plus SoCalGas for natural gas. LADWP, SCE, and state programs periodically offer incentives for heat pump replacements.

## Recommended systems

- [Heat pumps](https://ethohome.com/services/heat-pumps/): Replaces both an AC and gas furnace with one all-electric system that thrives in LA's mild winters and aligns with LADWP/SCE electrification incentives.
- [Ductless mini-splits](https://ethohome.com/services/ductless-mini-splits/): The cleanest way to add cooling and heating to older Westside, Silver Lake, or Pasadena homes that only have wall heaters or lack duct space.
- [AC replacement](https://ethohome.com/services/ac-replacement/): Paired with a South Coast AQMD-compliant Ultra-Low-NOx furnace, a variable-speed central AC keeps San Fernando and San Gabriel Valley homes cool through 105°F heatwaves.

## Questions

### Why do replacement gas furnaces in Los Angeles have to be Ultra-Low-NOx?

The South Coast Air Quality Management District (SCAQMD) Rule 1111 requires residential natural gas furnaces installed in the LA basin and valleys to meet strict 14 nanograms per Joule (ng/J) nitrogen oxide limits. We supply compliant Ultra-Low-NOx furnaces—or help you switch to an all-electric heat pump.

### My LA bungalow has small side-yard clearances—what outdoor unit fits best?

Narrow lot lines in Silver Lake, Culver City, and the Valley often leave less than 3 feet between the house wall and the property fence. Slim-profile side-discharge inverter heat pumps and condensers fit comfortably along narrow side yards and run significantly quieter than traditional top-fan cubes.

### Does Etho Home handle LADBS permits and HERS testing in Los Angeles?

Yes. The Los Angeles Department of Building and Safety (LADBS) and neighboring cities like Pasadena, Burbank, and Torrance require mechanical permits and HERS verification for HVAC replacements. Our licensed partner crews handle both.
