SwiftSize is an HVAC (heating, ventilation, and air conditioning) load calculator for residences. It is designed to very quickly measure off a home's exposures "on the fly" and produce accurate results for sizing heating and air conditioning equipment. Now generates a shareable PDF Report! 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 you're doing something wrong! SwiftSize is not a comprehensive room-by-room heat loss/heat gain/CFM calculator. If it were it would be SlowSize! It's intended for the equipment changeout market, not the new construction market.
