Heat Load/Loss Calculations

How Load Calculations Work

The purpose of a load/loss calculation is to determine how much heating or cooling a house needs to maintain a comfortable indoor environment. The calculation examines both how the house gains heat during hot weather and how it loses heat during cold weather. When the calculations are finished, the technicians can tell what size of cooling and heating system fits the home needs. Errors in these calculations will lead to wasted energy and money spent on replacing an HVAC system that's either too large or too small for the home.

What Goes Into a Load/Loss Calculation

When our Breathe Easy of CNY team performs a heat load/loss calculation, we take into account numerous factors about the house: square footage, insulation, number of windows and their facing, heat from lighting and appliances, and the number of people in the home. Using this accumulated data, we can get a precise result for sizing an HVAC system.
