BTU (British Thermal Unit)
BTU (British Thermal Unit) is a standard measurement used in heating and cooling to show how much heat something can produce or remove. Think of it like measuring the power of a heater or air conditioner - the higher the BTU number, the more powerful the unit. When looking at resumes in the heating and cooling industry, you'll often see this term because technicians need to calculate and work with BTUs to make sure they install the right size equipment for different spaces. It's similar to how we measure a car's power in horsepower, but for heating and cooling equipment.
Examples in Resumes
Installed and maintained heating systems ranging from 50,000 to 100,000 BTU
Calculated BTUs required for commercial building heating solutions
Specialized in high-efficiency BTU unit installations and upgrades
Performed maintenance on 75,000 British Thermal Unit heating systems
Typical job title: "HVAC Technicians"
