When You Replace A HVAC System, A Load Calculation Should Be Done

This dates me, but I remember when you installed or replaced an air conditioning system for a house, you took the square footage of the building, times it by 12, added 6000, and rounded it up to the nearest 1/2 ton (6000 BTU/h). For example, a 1200 square foot home = 1200 x 12 + 6000 = 20400. Since 12,000 BTU/h = 1 ton of cooling. The nearest 1/2 ton to 20400 would be 24,000 BTU/h or 2 ton. The formula worked well for the old 8 SEER systems. The only R rating we were concerned with then was at the movies. Most houses were heated by gas or oil, and when you added air conditioning, you had to change the blower motor and install a fan center. This increased the fan speed in the AC mode. That was a long time ago and changes in HVAC technology have greatly improved. Energy efficiency is now a concern. Homes are better insulated and engineering improvements to doors and windows have changed exceedingly. For example, an older home with a 3 ton A/C system that once had single pane window glass, and little or no insulation in the walls or attic, could now have newer windows and insulation. With these improvements, a new 2.5 ton AC system could now do the same job as the old system. Today, many factors go into calculating the values to correctly size a system. For houses, the best method is called a Manual J. This heat and cooling load calculation, developed by the Air Conditioning Contractors of America (ACCA), can be manually or computer calculated. I suggest a computerized version because it provides input values for an easier and faster calculation. Most software versions offer instructions on data input. A properly sized HVAC system, combined with a seasonal service check, will provide years of efficient operation.
