Best AC for Los Angeles — 2026 Buying Guide | LC Heating & Air

How to Choose the Right AC for LA

Los Angeles has a Mediterranean climate with hot, dry summers averaging 85–100°F from June through September. Your AC needs to handle sustained heat without excessive humidity loads, making SEER rating and proper sizing critical.

Key factors:

SEER2 rating: California requires 14.3 SEER2 minimum. We recommend 16+ for meaningful savings.
System size: Oversized units short-cycle and waste energy. Undersized units run constantly. A Manual J calculation ensures proper sizing.
Refrigerant: New R-32 systems are more efficient and future-proof vs R-410A.
Noise level: Important for close-neighbor lots common in LA.

Goodman vs Daikin: Which Brand?

Both brands are manufactured by the same parent company (Daikin Industries) and share core compressor technology.

Goodman: Best value. Reliable workhorse. 10-year parts warranty with registration. Lower price point. Great for budget-conscious homeowners.
Daikin: Premium features. Inverter technology on higher models. 12-year parts warranty. Quieter operation. Better for homeowners wanting top-tier efficiency.

Both brands are available through LC Heating & Air with professional installation.

What Size AC Do I Need?

Rule of thumb for Los Angeles (Climate Zone 9):

1,000 sq ft: 2 tons (24,000 BTU)
1,500 sq ft: 3 tons (36,000 BTU)
2,000 sq ft: 3.5–4 tons (42,000–48,000 BTU)
2,500 sq ft: 4–5 tons (48,000–60,000 BTU)

These are estimates. A professional Manual J load calculation accounts for insulation, window exposure, ceiling height, and ductwork condition.
