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

Before hiring an HVAC contractor in Stockton to install, repair, or maintain your heating or cooling equipment and systems, it is crucial to ensure that they are licensed and familiar with the Stockton Mechanical Code. This code is a locally adopted version of the California Mechanical Code designed and implemented to ensure the safety and efficiency of your HVAC systems and work involving these systems. Adherence to the Code and other globally-accepted ventilation and indoor air-quality standards guarantees the safety and efficiency of HVAC work, increases the overall comfort and livability of your home or workspace, and can lead to reduced energy bills.

Some of the services provided by licensed and experienced Stockton HVAC contractors include the following:

Are You Licensed as an HVAC Contractor in Stockton?

You must be licensed by the California Contractors State License Board (CSLB) to perform heating, air conditioning, ventilation, and refrigeration work worth more than $500 (cost of labor and materials inclusive) in Stockton. The CSLB issues HVAC contractor licenses under the following classifications:

• C-20 - Warm-air Heating, Ventilating, and Air-conditioning Contractors: This license allows HVAC contractors to install, maintain, and repair heating, ventilation, and air conditioning systems, including HVAC systems that use solar energy.
• C-38 - Refrigeration Contractors: This license allows HVAC contractors to install, maintain, and repair refrigeration systems, refrigerated rooms, insulated refrigerated spaces, temperature insulation, air-conditioning units, ducts, blowers, registers, humidity, and thermostatic controls for the control of temperatures below 50 degrees Fahrenheit, or 10 degrees Celsius.

The CSLB typically only issues licenses to applicants who meet specific requirements, including the following:

• Being at least 18 years old
• Having acceptable and verifiable HVAC work experience of at least four years
• Passing the CSLB's licensing examination
• Passing a background check

Hiring CSLB-licensed HVAC contractors guarantees that your project will be executed competently and satisfactorily, and you should always seek to hire these types of contractors, even for jobs that cost less than $500. Please be aware that performing HVAC work without an appropriate license in Stockton is a misdemeanor that carries statutory and administrative penalties of up to six months in jail and $15,000 in fines.

Will You Be Doing the Work, or Do You Outsource the HVAC Work in Stockton?

Although HVAC contractors in Stockton are generally well-qualified to handle HVAC projects on their own, they often have to outsource work to third parties under certain circumstances. This often happens in large-scale projects. Therefore, when planning an HVAC project, it is important to verify with your contractor if the work will be outsourced. If it will, we recommend you take the following actions to avoid any issues with the subcontractors involved in your project:

• Confirm that each subcontractor is appropriately licensed and experienced.
• Verify the subcontractors' bond and insurance coverage.
• Insist on getting lien waivers to ensure that you are not held liable if the primary HVAC contractor fails to pay the subcontractors on time.

Are You a Fully Insured and Bonded Stockton HVAC Contractor?

Stockton HVAC contractors must maintain a $25,000 surety bond and carry workers' compensation insurance for their employees, if any. While these contractors are not required to carry general liability insurance, they must disclose their liability insurance status to homeowners who wish to engage them.

Always verify that the HVAC contractor you plan to hire is adequately insured and bonded before signing any agreements. You can do this by requesting copies of their insurance and bond certificates and verifying these documents with the appropriate issuing organizations.

Do You Offer Any Warranties on Your HVAC Work in Stockton?

Warranties are an essential criterion to look for when searching for an HVAC contractor in Stockton. Reputable HVAC contractors usually offer warranties that cover their workmanship for one to two years and the materials used in projects for five to ten years. Bear in mind that the specific terms and validity periods of these types of warranties usually vary depending on the contractor and the HVAC equipment being installed or replaced.

Therefore, always request a written copy of any warranty you are offered and review its terms and conditions. Finally, be wary of HVAC contractors who are hesitant to discuss warranties or who claim they don't offer them.
