In light of the above, it is smart to ask your HVAC contractor the following questions before signing any contract:

What Do I Need to Know Before Hiring an HVAC Contractor in Oakland?

Hiring a professional HVAC contractor to install, upgrade, or maintain your heating, ventilation, and air conditioning systems is the only way to guarantee the smooth operation of these systems. Professional Oakland HVAC contractors adhere to relevant locally implemented building codes and ventilation/indoor air quality standards when providing their services. This will ensure that your HVAC equipment runs effectively, improve the comfort of your living space, and lower your energy costs.

  • Designing and installing HVAC systems for newly constructed buildings

Are You Licensed as an HVAC Contractor in Oakland?

Any work done on heating, ventilation, air conditioning, or refrigeration systems and equipment in Oakland worth $500 or more must be handled by a state-licensed HVAC contractor. State licenses are issued by the California Contractors State License Board (CSLB). This agency currently offers two types of HVAC licenses:

  • A C-20 license authorizes work on warm-air heating, ventilation, and air-conditioning systems and equipment associated with these systems. This license also covers HVAC systems that use solar energy.
  • A C-38 license authorizes work on refrigeration systems and equipment used to regulate air, liquid, or gas temperatures below 50 degrees Fahrenheit or 10 degrees Celsius.

It is important to note that HVAC contractors with a C-20 license are not permitted to provide services within the scope of the C-38 license without first obtaining this type of license, and vice versa. HVAC contractors interested in acquiring these CSLB-issued licenses must meet eligibility requirements that include the following:

  • Gaining at least four years of acceptable and verifiable HVAC work experience
  • Undergoing federally-mandated certification at an EPA-approved agency (required for applicants who wish to work on refrigerant-containing equipment)
  • Passing a CSLB-administered licensing examination and background check

HVAC contractors who meet these requirements and who are subsequently licensed by the CSLB are deemed qualified to provide high-quality services. Therefore, we recommend always hiring licensed contractors for your HVAC work in Oakland, regardless of the project's cost.

You can confirm if your preferred HVAC contractor has a valid CSLB-issued license via the board's Check a License platform.
