The third – and most crucial law for energy savings – reveals that the power consumed by these components is related to the cube of their speed. So, a small reduction in speed can lead to a significant drop in power usage and, consequently, energy costs.
What is the Affinity Law – and what does it have to do with your HVAC system?

The sales people tell you will save 30% on your heating and cooling costs with a variable speed compressor. My 16 year old system cost is high in the summer for 3 months maybe $100 per month. According to SECO over the last 12 months I spent $583 running cooling and heating. 30% of that is $174.90 / year. Multiply that by 16 years I have lived here I could have saved $2798.00.
