The New Mexico MM-3 Heat, Vent and Air Conditioning examination is part of the contractor licensing process administered for the New Mexico Construction Industries Division. PSI provides contractor licensing and examination services for New Mexico.
The MM-3 examination evaluates trade knowledge across major HVAC and mechanical subject areas. The exam content includes motors, controls and low-voltage wiring; piping; heating and cooling general knowledge; heating and cooling equipment and components; refrigerants and refrigeration; and ductwork, ventilation and exhaust.
These areas require both practical HVAC knowledge and familiarity with technical references. Candidates may encounter questions that involve equipment operation, refrigeration principles, mechanical systems, air distribution, piping, controls, duct construction, ventilation, and applicable code requirements.
The examination contains 100 questions, requires a 75% passing score, and allows 245 minutes for completion. The exam is open book, making familiarity with the approved technical references an important part of preparation.
The examination content is organized across six major categories. Motors, Controls, and Low Voltage Wiring contains 20 questions. Piping contains 10 questions. Heating and Cooling General Knowledge contains 20 questions. Heating and Cooling Equipment and Components contains 15 questions. Refrigerants and Refrigeration contains 15 questions. Duct Work, Ventilation, and Exhaust contains 20 questions.
The New Mexico MM-3 Heat, Vent and Air Conditioning examination is an open-book test. Candidates are responsible for bringing permitted reference materials to the testing center and complying with the examination provider's reference-book rules.
Open-book testing places a premium on navigation skills. A candidate who knows the general subject but cannot quickly locate the applicable section, table, chart, formula, or code requirement may spend too much time searching. Study sessions should therefore include regular reference practice in addition to technical review.
Reference materials used in the examination must comply with PSI's requirements. Approved books may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used. Temporary tabs such as Post-It notes are not allowed. Reference materials containing writing are not permitted, and candidates may not write in the references during the examination session.
Candidates are also prohibited from bringing loose or attached papers with their approved references. A silent, non-printing, non-programmable calculator may be used in the examination center.
Use the highlighted and tabbed books provided with this package throughout your preparation. Repeatedly locating HVAC formulas, mechanical-code provisions, duct information, refrigerant data, piping information, and equipment concepts can build familiarity that supports more efficient exam-day navigation.
The MM-3 trade examination is one part of New Mexico's contractor licensing process. Contractor licensing services are coordinated through the New Mexico Construction Industries Division and PSI.
The licensing process involves both the individual's Qualifying Party qualifications and the contractor business entity. Candidates should coordinate exam preparation with their application progress so testing, documentation, and business licensing steps remain organized.
New Mexico regulates construction contracting through the Construction Industries Division. Mechanical contractor classifications are tied to defined scopes of work, and applicants must qualify for the classification appropriate to the contracting work they intend to perform.
The MM-3 classification concerns heat, ventilation, and air-conditioning work. Candidates preparing for this classification should be ready to demonstrate knowledge of HVAC systems and associated mechanical work through the examination and the state's licensing process.
New Mexico contractor licensing requires a properly qualified individual to serve as the Qualifying Party for the licensed entity. The Qualifying Party must complete the applicable experience, application, and examination requirements for the classification being sought.
The contractor business must separately complete the licensing requirements applicable to the company. This distinction is important because passing a trade examination by itself does not create an active contractor license. The examination supports qualification of the individual, while the contractor license is issued through the applicable company licensing process after all required documentation has been completed.
Book Preparation: The package books are highlighted and tabbed for exam preparation. Candidates should use the prepared materials consistently during study sessions so the location and organization of important subjects become familiar before exam day.
The MM-3 examination covers several major HVAC disciplines, so an effective study schedule should divide preparation into manageable subject areas rather than attempting to study every reference from beginning to end.
Motors, Controls, and Low Voltage Wiring accounts for 20 questions. Candidates should review electrical and control concepts relevant to HVAC equipment, including motors, control circuits, system components, and low-voltage control functions.
Piping contains 10 questions. Preparation should include pipe-trade concepts, fittings, measurements, materials, and mechanical-system piping. Regular use of IPT’s Pipe Trades Handbook can help develop quicker reference navigation for this section.
Heating and Cooling General Knowledge contains 20 questions, while Heating and Cooling Equipment and Components contains another 15. Candidates should build a solid understanding of heating and cooling principles, system operation, components, installation concepts, and equipment functions.
Refrigerants and Refrigeration represents 15 questions. Study refrigeration-cycle principles and become comfortable using the refrigeration reference and Pressure and Enthalpy Charts. Practice matters because chart-based questions may require both conceptual understanding and efficient interpretation of technical data.
Duct Work, Ventilation, and Exhaust accounts for 20 questions. This section makes the Ductulator, Uniform Mechanical Code, HVAC Duct Construction Standards, and sheet-metal material particularly important. Candidates should practice identifying duct-sizing information, construction requirements, ventilation provisions, and related air-distribution concepts.
Since the exam contains 100 questions and allows 245 minutes, candidates should practice balancing careful reading with efficient reference use. Avoid spending excessive time searching a single book for a difficult question. Learn the organization of each reference and practice deciding which source is most likely to contain the answer before beginning the search.
