Software for HVAC Calculations
Heating, ventilating, and air conditioning technicians need accurate calculations when determining the size air conditioner or heating unit that you need. While you can manually do these calculations, you can also use software programs to help you with this process, especially if you're a do-it-yourselfer. All of these programs require a fee to use, but you can order them directly from the company. Does this Spark an idea?
