What is a C-61/D-62 Air and Water Balancing Contractor?
"An air and water balancing contractor installs any device and performs any work related to providing a specified flow of air in all types of existing heating and cooling systems and/or related to providing a specified flow of water in water piping systems" - CSLB.GOV
The D-62 is the classification required in the state of California for all persons looking to contract for air and water balancing services where the cost of labor and materials exceeds $500
Typical duties associated with water and air balancing
Air and water balancing are two areas of expertise often offered together but are sometimes referred to separately.
Water balancing is commonly known as hydronic balancing and air balancing known as HVAC balancing.
Hydronic balancing is a method of optimizing a buildings heating and cooling system to operate at an intended indoor climate.
Some of the duties associated with water and air balancing include:
The ultimate goal of water and air balancing is to maximize optimum energy efficiency and operating cost.
Hospital Air Conditioning Systems
Contractors that specialize in HVAC balancing can work in a variety of setting including:
- Commercial Apartment Buildings
Their goal is often to achieve energy efficiency but also to help clients comply with air and water balancing standards.
So that medical facilities meet their Hospital Accreditation standards, contractors that hold the D-62 license must assess an existing HVAC system and ensure that it meets temperature requirements.
However they may function as a subcontractor under a General B as part of a larger project that calls for their specialized services.
General Contractors oversee that the subcontractor has executed their duties in adherence to code and to the specific requests of a client.

The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California. Their sole responsibility is to protect the consumer public.
They ensure that anyone charging over $500 for construction services is qualified and registered with the state.
- State wide task force that engages in sting operations to stop un-licensed construction activity.
- Getting caught contracting without a license in California is punishable with fines up to $15,000 and 6 months in the the county jail.
- The CSLB issues the garage doors contractor license to contractors in the state of California.
C-61/D-62 License Requirements
To get the air balancing contractor license in California, you must meet the following requirements:
You must also have:
What is a Journey level experience?
Journeyman level experience means that you have worked unsupervised full time for an HVAC balancing company, or for a contractor that holds the D-62 License.
- A journeyman can perform all of the duties associated with his or her trade.
The CSLB will want to see four full-time years over the last ten years.
The years do not need to be consecutive, but they do need to be four years in total.
Signature of a Qualifying Individual
The following people may be used as Qualifying Individuals to sign off on your experience when applying for the air balancing contractor license:
Filling out the Contractor License Application
Your Qualifying Individual will also need to provide a brief but detailed description of your knowledge and skillset.
The way this description is written will be critical to whether or not your application is accepted. For example:
“Ed is a nice guy and very experienced” is not descriptive enough for the CSLB.
The people reviewing your application will want to see something more like:
"Ed has experience conducting air velocity testing, hydronic balancing, air balancing, and fan performance analysis.
He has tested, balanced and calculated air circulation with adherence to OSHA standards" etc.
The description written by your qualifying individual will need to include the core skills required for the air balancing contractor license.
HVAC Balancing Work Experience
You must be prepared to submit documentation supporting the experience you claim to have.
The Contractors State License Board gives you a few ways that you can prove your experience.
- Tax Returns
- Check Stubs
- Material Order Invoices or Receipts
The CSLB receives thousands of applications per month so there is a good chance they won’t document your experience.
However, if you are one of the applicants that get reviewed you will need to be ready to submit something.
The CSLB does not accept pictures of projects.
Application Processing, Fees and Criminal History
The time it takes to get your application processed and assigned a test date fluctuates throughout the year.
Typically you can expect:
- 6-8 Week Application Processing Time
- 3-4 Week wait for an Exam date
I have seen some situations where applicants got their test date sooner and some where they got their test date much later.
The most common reasons your application would get held up are:
- Time of year (processing time slows down during the holidays)
- Criminal History
- Proving Experience
- Mistakes on your application
The current state fees are:
1. $330 State Application Fee ( one time fee per application sent to the state board )
2. $200 License Activation Fee ( paid every two years )
You will also need to pay for live scan fingerprinting.
Upon passing the exam, the state board requires you to have a Contractor Bond number. A construction bond is a security deposit issued by a surety company. Bonds are designed to protect the consumer public against contractor default.
They act as protection mechanisms for clients from unethical or illegal actions performed by contractors. Bonds also ensure that subcontractors get paid for their work.
Furthermore, they ensure or that a contractor performs his duties as stated in a contract. Construction bonds protect employees, suppliers, sub-contractors or clients against a contractor's failure to abide by an agreement.

Can you get a Contractors License with a Felony in California?
Having a criminal record in no way stops you from getting the garage door license. I have personally helped guys with all types of criminal records obtain multiple licenses.
The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.
BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting. The CSLB handles criminal records on a case by case basis.
Remember, their responsibility is to protect the public.
In my experience, they primarily concerned with criminal charges associated with: Fraud, Embezzlement or Forgery.
