Inaugural Edition January 7, 2012
My inaugural edition will be to attempt to set the record straight about residential air conditioning systems. The general concenus is "no big deal", just replace the condenser, evaporator and air handler and one is good to go. I must say it would be great if in realty that was all there was to it. Possibly years and years ago before building science began to understand that if we weatherized a residential structure, or possibly replaced the windows to use just two examples, that a corresponding change in the tonnage of installed air conditioning systems would also be required. If that were not enough, down the road we also came to understand that we must began to give due diligence to the ventilation systems (exhaust and fresh air) if the structure were to preform correctly.
Unfortunately most of this information has never gotten down to the level of a Residential Air Conditioning Contractor. As a result the majority continue to use the old rule of thumb of 400 square feet per ton. The problem is a Rule Of Thumb can equal as shown.
My point is that the installation or replacement of an air conditioning system is much more complex than most people know. In one of my classes I use the below graphic to illustrate all the necessary steps that must be taken if any given system is to provide the homeowner a worry free system that will provide years of trouble free operation and a comfort level never before experienced.
I hope you will find this useful when it becomes neccessary for you make a very large purchase that will affect your comfort for years to come.
