Heating and Cooling in Long Beach, CA

The center of Long Beach is about 12.3 miles from our Paramount Boulevard shop, roughly 20 minutes without traffic. The city held 466,742 people at the 2020 census, spread over about 51 square miles of land. Two things set it apart for HVAC work: summer fog at the shore against hotter afternoons inland, and a gas system run by Long Beach Utilities instead of SoCalGas.

Belmont Shore fog or Bixby Knolls heat: which load do you have?

Low clouds and fog often form overnight in summer and clear by afternoon, then a westerly sea breeze keeps the shore mild. Long Beach Airport, about 4 miles inland, is the official weather station, and its temperatures swing more than the immediate coast.

The airport averages a high near 83°F in August, yet the city still sees about 23 days a year above 90°F and about two above 100°F. A Belmont Shore house may run its AC only on those days. A North Long Beach house runs it far more often.

Near the water, salt attacks condenser fins and fasteners, so the outdoor unit can fail while the rest of the system looks fine. Oversizing is a risk there too: a big unit on a mild day shuts off too fast, which we call short cycling.

Inland, age is the issue. Bixby Knolls, California Heights, Los Cerritos and North Long Beach were subdivided from Rancho Los Cerritos after 1916, and the oldest houses on those tracts were not built around central air. Ducts added later take tight routes and leak at the joints.

Census survey figures for 2020 to 2024 list only 41% of units as detached, with 35% in buildings of two to 19 units and 18% in buildings of 20 or more. About 59% of households rent. The median unit dates to 1959, and 19% predate 1940.

Historic districts add a step. The city says exterior alterations there require a Certificate of Appropriateness, while interior work and routine repair stay outside it. Its August 2021 case log shows a California Heights condenser replacement approved as a minor case. Check the district map or call Planning at (562) 570-6194 before you place the unit.

Heating and cooling in Long Beach by house and neighborhood

Long Beach Utilities gas, Edison power and the West Ocean permit counter

Mechanical permits run through the City of Long Beach Building and Safety Bureau. The Permit Center is at 411 West Ocean Boulevard, 2nd Floor, and (562) 570-7648 reaches both the counter and mechanical plan check. Express appointments run Monday to Friday, 8:00 AM to 3:30 PM, from 9:00 AM on Wednesdays, and simpler jobs may qualify for the express mechanical permit application.

That form, revised in May 2026, covers a same-size HVAC replacement up to 33,000 Btu/h in total. A 3-ton system is 36,000 Btu/h, so it falls outside that line. It also requires verification by an ECC-Rater (formerly called a HERS rater) on change-outs.

Long Beach Utilities runs its own gas system, so SoCalGas phone numbers are the wrong starting point here. Its gas emergency line is (562) 570-2140. Electric service is generally Southern California Edison. Check the name on each bill.

I-405 splits the city north and south, I-710 follows the western edge to the port and I-605 serves the southeast. Long Beach Airport, Cal State Long Beach, El Dorado Regional Park and Bluff Park work as landmarks. Signal Hill, which Long Beach surrounds, is a separate city, so confirm your address first.
