No — if your existing gas water heater is working, you're not required to replace it. The 2027 BAAQMD rule applies to new installations only. However, when your current unit fails, you'll need a compliant replacement (heat pump, electric tankless, or solar). Given current rebate availability — up to $4,900 through TECH Clean CA + federal IRA credits — 2026 is an excellent time to plan a proactive upgrade.
Gas tank water heater replacement typically runs $900–$1,800. Tankless installation costs $1,500–$3,000. Heat pump water heater installation ranges from $1,800–$3,500 before rebates — after TECH Clean CA and federal tax credits, the net cost can drop by $2,000–$4,900. We always provide written quotes before starting any work.
We install all major brands including Bradford White, A.O. Smith, Rheem, State, American, Navien, Noritz, Rinnai, and more. For gas tank units, we typically recommend Bradford White. For tankless, we prefer Navien or Noritz. For heat pump, Bradford White AeroTherm, Rheem ProTerra, and A.O. Smith Voltex are our top picks.
Yes — always. We pull all required city and county permits as part of every installation at no extra charge. Permit requirements vary by city, but we handle the entire process so you don't need to make any separate filings.
