CLF stands for Cooling Load Factor - a home’s cooling load is a measure of how much an air conditioning unit needs to effect cooling in a room of a given size. It is measured in British Thermal Units, which is usually abbreviated to BTUs. The CLF is the cooling load at a given time compared to the heat gain from earlier in the day. When it comes to a new AC installation or to perform old AC unit replacement, one of the first tasks that needs to be done is to do a load calculation. Estimating a home’s cooling load allows for the right size of air conditioner replacement system to be installed. 


How to Estimate Your Home’s Cooling Load

  • Get the size of the home that needs cooling in square feets. You can do this with a measuring tape, but for an entire house, it may be helpful to view the blueprints or search the local county auditor’s website for the home’s square footage.
  • Multiply the square footage by 20. This is the measure of the BTU cooling load of the space.
