Before you jump, think about this. Number 1 ask your a/c contractor to perform a manual J work sheet to insure optimal system performance. #2 Do not ever quess or automatically assume the tonnage and size of the old system is correct. #3 Highly consider a system that has a multiple stage outdoor compressor and a infinite speed ECM indoor blower motor. #4 Make sure the thermostat being used does not negativity effect the operation of the system. Many new systems require there own high end stats so the system will run on all the heating and cooling stages! #5 Make sure a high flow air filter and housing are installed.#6 Check for sufficient attic insulation and a properly sized and functional attic heat extraction system. BTW, you should barely be able to even hear your system. If you do, this most likely means the static system pressure is too high. This is a cause of improper duct, trunk sizing or inadequate number of vents or returns
