Manual J Premium Heat Loss/Gain Calculation;  


The manual J heat loss is an industry standard. The premium service we can change window, door, and insulation values upon your request. By doing this it will help you decide what home upgrades make the most sense financially before deciding on replacing your heating or cooling appliance. This will reduce the heat gain or heat loss and allows you to buy smaller equipment and save more money on the appliance price, installation, and increased fuel savings. Over sizing your appliances will cost more to install, more to operate annually and more in maintenance. Upgrading the home before replacing the heating or cooling equipment makes the most sense. Changing the heating or cooling appliance first then doing upgrades to the home will make properly sized equipment over sized after the upgrades to your home.
