Residential Heat Loss Plan Prices - Premium Plan


Premium Plan .............................................................Price $129.95

The manual J heat loss is an industry standard. The premium service enables us to modify window, door, and insulation values upon your request. By doing this, you can determine which home upgrades are most financially sensible before deciding whether to replace your heating or cooling appliance. This will reduce heat gain or loss, enabling you to purchase smaller equipment and save on appliance costs, installation, and fuel expenses. Over-sizing your appliances will cost more to install, operate annually, and require more 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 oversized after the upgrades to your home.
