SwiftSize is an HVAC (heating, ventilation, and air conditioning) load calculator for residences. It is designed to very quickly measure off a homes exposures "on the fly" and produce accurate results for sizing heating and air conditioning equipment.
It is designed to minimize the on-site engineering time required by the HVAC professional. Less time engineering means more one-on-one time with the customer!
HVAC heat loads can be a cumbersome and time consuming and tend to distract from time spent consulting. SwiftSize addresses this problem by allowing complete heat loads to be performed in mere minutes. If it takes you more than 10 minutes with SwiftSize youre doing something wrong!
SwiftSize is not a comprehensive room-by-room heat loss/heat gain/CFM calculator. If it were it would be SlowSize! Its intended for the equipment changeout market, not the new construction market.
