There is an old joke among HVAC contractors. When bidding on a replacement system for a customer, step back 100 feet from the house and hold up your hand. If three fingers will block the view of the house, install a three-ton unit. If it takes four fingers to block the view, then install a four-ton unit. That meager attempt at humor does highlight an issue that has been kicked around since the beginning of the industry. Are load calculations necessary? If so, how do you properly size a heating and air conditioning system for a house or commercial building?

Back in the rural south, around 1940, power companies would mail flyers to their customers at the beginning of summer. These flyers would give tips on how to stay cool during the hottest days ahead. Some of the tips were; grow ample shade around your residence, stay inside during the hottest part of the day, use open windows for increased air circulation, and keep wet towels available to cool your forehead and neck. Homes, in those days, were designed to facilitate air movement. Large porches and arched ceilings in hallways enhanced air currents that moved freely through the structure. These conditions were the norm for homeowners before the availability of affordable air conditioning.
