Many people are under the impression that all HVAC systems are basically the same.
On one hand, this is a true statement.
However, did you know that the efficiency rating can vary depending upon the region you are living in? Regulatory guidelines allow this discrepancy in order to allow HVAC dealers to offer what works best for you. If you live in the South, where winters are milder and you don’t experience extreme cold for months on end your furnace has a lower efficiency requirement than those up North. This may allow you to save some money upfront on the unit as well. HVAC manufacturers are on top of all the government requirements for each region and produce models that are needed for the dealers in that area. A higher demand for air conditioners in the south and efficient heating systems in the north drive the HVAC industries’ manufacturers to keep up with changing trends. For instance, if the industry sees a growth in population in one region or another they may increase production of HVAC units that will meet the needs of the people moving to that area and decrease them in another place that is seeing a decline. This allows them to save money by not making an excess of units that will sit unsold. A lot goes into the future planning of a manufacturing schedule in order to keep up with supply and demand. This is also required so that HVAC manufacturers maintain profitability and they don’t waste money on merchandise that will just sit there. It is very interesting to see how much planning goes into HVAC units that we take for granted each day.
