Did you know that a Manual J Calculation has to be performed before every AC installation? If your contractor sells you a system without performing the calculation then your new system is not up to a code and you will fail inspection. More than likely you will end up with too small or too big of an AC system which will result in higher energy bills and repeat service repairs because your system needs to be sized perfectly for your home. If you have the wrong size system in your home then the system cannot operate the way it was designed and it can fail prematurely. So call KCH today and let professionals install the right equipment for your home or business in timely fashion.
