This document compares the costs and sales projections for equipment with minimum, mid, and high efficiency for a heating, ventilation, and air conditioning (HVAC) company. It shows that higher efficiency equipment has higher upfront costs but requires selling fewer jobs to reach the desired annual sales goal of $1 million. With mid-efficiency equipment, 94 jobs would need to be sold, while high-efficiency equipment would require selling 78 jobs to hit the annual sales target. The document also notes that the national average overhead for an HVAC company is between 28-32% according to the Department of Labor.
