Load Calculation
Load Calculation is a fundamental planning process in heating, ventilation, and air conditioning (HVAC) work. It's like creating a detailed blueprint that helps determine the right size of heating and cooling equipment needed for a building. Think of it as measuring a space to figure out exactly how powerful an air conditioner or heater needs to be - not too big (which wastes money) or too small (which won't do the job). HVAC professionals use this process to ensure comfort and efficiency in homes and buildings. When you see this term in a resume, it shows that the candidate knows how to properly plan HVAC systems rather than just installing equipment.

Example Interview Questions
Senior Level Questions
Q: How would you approach load calculations for a large commercial building with multiple zones?
Expected Answer: A senior technician should explain the process of breaking down the building into zones, considering factors like sun exposure, occupancy patterns, and equipment heat output. They should mention using professional software and how they would coordinate with architects and building managers.
Q: Tell me about a time when your load calculations prevented a major system issue.
Expected Answer: Look for answers that demonstrate how their accurate calculations saved money, prevented comfort issues, or avoided system failures. They should explain how they identified potential problems through the calculation process.
Mid Level Questions
Q: What factors do you consider when performing a residential load calculation?
Expected Answer: They should mention checking insulation levels, window sizes and types, room dimensions, local climate data, and occupancy patterns. Should understand how these factors affect heating and cooling needs.
Q: How do you explain load calculation results to customers?
Expected Answer: Should demonstrate ability to translate technical information into simple terms, explain why proper sizing matters, and how it affects energy bills and comfort.
Junior Level Questions
Q: What basic measurements do you need to start a load calculation?
Expected Answer: Should know about measuring room dimensions, counting windows and doors, checking insulation types, and gathering basic building information.
Q: What software tools have you used for load calculations?
Expected Answer: Should be familiar with at least one common load calculation software and understand basic inputs and outputs.
