How Much Does a New HVAC System Cost in Orange County in 2025–2026? (Real Prices from a Local Contractor)

Updated November 20, 2025

Replacing your HVAC system in Orange County is one of the biggest home investments you’ll make — and prices have jumped 18–25% since 2023 because of new refrigerant rules, higher efficiency mandates, and labor shortages.

I’m J Martin, owner of J Martin Indoor Air Quality (California License #998956). We’ve installed over 5,000 systems across Anaheim, Irvine, Yorba Linda, Huntington Beach, and the rest of Orange County since 2003. Here are the exact prices we’re quoting right now (November 2025) so you know what to expect before anyone knocks on your door.
