Why verify a California HVAC contractor?

HVAC work touches refrigerant, gas, and high-voltage electrical systems — most states require a separate license to do it. Verify the contractor's HVAC credentials before letting anyone open up your system.

How to hire a California HVAC contractor safely

  1. Verify the HVAC license is active and covers the specific equipment (gas, refrigerant, ducting).
  2. Confirm the technician is EPA Section 608 certified for refrigerant handling.
  3. Ask whether they pull mechanical permits — most municipalities require one for system replacements.
  4. Get a Manual J load calculation in writing for any new system install.
  5. Insist on a written labor warranty (1+ year) on top of the manufacturer's parts warranty.

Frequently asked questions

Why does HVAC need its own license?

HVAC combines high-voltage electrical, gas piping, refrigerant (regulated by the EPA), and structural ducting — all in one job. Most states require a dedicated HVAC license to ensure the contractor is qualified across all four areas.

How much does HVAC replacement cost?

A full system replacement (AC + furnace) typically runs $7,000–$15,000 installed for a single-family home, depending on size, efficiency, and ductwork condition.

Can a regular electrician install an HVAC system?

No. While an electrician can wire the disconnect, the HVAC equipment install itself — refrigerant lines, gas, condensate, ducting — must be done by a licensed HVAC contractor in nearly every state.
