They must also thoroughly understand the refrigeration cycle and refrigerants.  \nHVAC design relies heavily on an understanding and analysis of psychrometric principles. Besides technical expertise, candidates should possess knowledge of HVAC standards and guidelines. Ask questions with technical aptitude in mind to narrow your list of eligible candidates.  \n1. What was your most challenging project, and what did you learn from it?  \nAsk candidates for an example of a challenging project to determine their level of expertise and the processes used to uncover solutions.  \nIf confronted with an exceptionally complicated HVAC problem, engineers need to know when to reach out to other HVAC professionals for a solution. The ability to understand complex processes and learn from challenges is vital and determines the success of a project.  \n2. What are the pros and cons of VAV and CAV systems?  \nHVAC engineers must understand the benefits and drawbacks of a variable air volume (VAV) system versus a constant air volume (CAV) system to make the right decision for a project. Engineers need to take all factors into consideration when designing a system to most efficiently heat and cool buildings and effectively manage indoor air quality.  \n3. What's the difference between sensible and latent heat loads?  \nIn the HVAC world, accurate application of energy principles results in comfortable building environments. Sensible heat refers to air temperature, while latent heat refers to moisture in the air. Calculations that include measuring airflow in cubic feet per minute (CFM) enable HVAC engineers to determine the correct size of an HVAC system.  \n4. How do you calculate heating and cooling loads?  \nSizing HVAC units by heating and cooling loads requires following the proper methods.  \nAn HVAC load calculation shows the exact number of BTUs (British thermal unit) a certain size of space requires for sufficient heating and cooling. By definition, a BTU is the amount of heat required to raise the temperature of one pound of water by one-degree Fahrenheit.  \n5. What's your experience with sustainable HVAC solutions?  \nModern customers want new, sustainable HVAC solutions that deliver benefits to the environment and their wallets. If your company provides services such as geothermal, solar power, or hydronics, ask about the candidate's knowledge of those systems, so you can continue to provide eco-friendly solutions to your customers.  \nTechnology Interview Questions  \n1. How do you view mobile software in the HVAC industry?  \nEngineers and project managers profit by using HVAC job costing software to accurately track project costs, integrating financial data from sold estimates, job invoices, purchase orders, payroll, and accounts receivable. These tools allow your HVAC employees to perform better asa team and complete projects more efficiently.  \n2. What is your experience with using mobile technology on the job?  \nMobile technology allows an HVAC engineer or manager to easily view schedules, materials and labor costs, and other critical job information from anywhere.  \nOn the customer service side, team members can notify customers about the project in a timely manner. A seamless customer experience results in more return customers, and increased word-of-mouth referrals.  \n3.
