In Mississippi, you can earn an average rate of just over $16 per hour as an HVAC technician, which can easily go up to $23.90 as your experience increases. You can expect an annual salary of $33,500 and up to $49,500 for senior technicians.


The income that HVAC technicians earn in the state is among the top 51% of all career salaries in Mississippi. Of course, the income you can receive will depend on your experience, certification, and position.


Scope of Work


As an HVAC technician, you will work on HVAC systems which regulate the temperature and air quality in various buildings. You are expected to carry out tasks such as installation, design, preventative maintenance, repair, and testing.


Moreover, the types of projects you can tackle include office buildings, schools, individual houses, healthcare facilities, military buildings, and more.


The HVAC Contractor Licensing Process


The Mississippi State Board of Contractors is the body that regulates HVAC licensing in the state. If you want to work as an HVAC contractor, you need to acquire a license before you can take on any HVAC-related work. However, if you choose to work under a licensed contractor, you are exempted from getting a license.


The license necessary for HVAC contractors falls under Mechanical Work Certificate. This will include all aspects that relate to heating, ventilation, air conditioning, and refrigeration such as appliances, fuel gas systems, and ductwork.


Also, jobs with privately funded funds in excess of $100,000 or publicly funded projects in excess of $50,000 will require a state contractor’s license. Meanwhile, anything that is below that threshold doesn’t need any licensing requirement. You still need to comply with the local requirements implemented in your locality.


There are two state license categories, namely Commercial and Residential. You need to pay a $200 application fee for a commercial license and $50 for a residential license. To apply, you need to follow these requirements:


  • A proof of general liability insurance
  • A proof of worker’s compensation insurance
  • Your financial statement which has been reviewed by a CPA in the last twelve months containing at least a $20,000 net worth
  • A passing score in the Law and Business Management and trade examinations
  • Any proof of experience in HVAC projects


Board meetings are held every three months and they are held on the second Wednesday of January, April, July, and October. You will need to submit your application 30 days before the meeting and pass the examination during the same period.


As a licensed HVAC contractor in the state, you can work on all aspects of heating, ventilation, and air conditioning. For now, there is no continuing education requirement.


If you have obtained a license from another state, you can choose to apply for the state’s license reciprocity agreement. However, this is only applicable to the following states:



By applying for license reciprocity, you no longer have to undergo the licensing and examination process. To qualify, you should have a license which you have maintained for at least three consecutive years from one of the aforementioned states. This is just like having Mississippi HVAC certification.


The Testing Process


The exams held in the state are held by PSI Examination Services. To get your license, you should get a passing score in the Law and Business Management and trade exams. Once you have submitted your application, the Board will inform the PSI if you are qualified to take the exam or not. You will also receive a confirmation email from PSI.


The HVAC trade exam consists of 80 questions which you should answer within four hours. To pass, you need a passing score of at least 70%. The questions include the following topics:

Information about EPA Section 608 Certification

The Environmental Protection Agency requires any technician who handles refrigerants to obtain an EPA certification as stated under Section 608 of the Clean Air Act. To obtain the certification, you need to get a passing score on an EPA-approved examination. This is not done by the state, so is not technically a Mississippi HVAC certification, however it is very necessary to advance your career in the field.
