3 Types of Cooling and Heating Loads You Need to Know About

Properly sizing a new residential HVAC system is of utmost importance. If the system is oversized or undersized, it will waste energy and not ideally perform. A key element of HVAC sizing is calculating its cooling and heating loads, or the needs and requirements of a home. Here are three main types of loads.

Design Load

This cooling or heating load is connected to designated comfort conditions in your home – in other words, pre-determined summer and winter temperatures that are considered typical for the sort of load your HVAC system will have to contend with during cold or hot weather. For a certain area and climate, the seasonal average temperatures might be 84 degrees in the summer and 18 in the winter. Various factors, including your home’s size, layout and energy efficiency, should be considered in determining just how much cooling or heating will be needed to bring your home to a pre-set comfortable temperature during outside average conditions.

Extreme Load

Extreme loads occur during the coldest or hottest days throughout the year. A skilled HVAC installation technician should never recommend a heating or cooling system based on an extreme load. This would render the system oversized for it’s daily work, resulting in many negative consequences of an oversized HVAC system.

Partial Load

In any home, the partial load is viewed as the most common requirement for your cooling or heating system. During a cold or hot day, much of the time the temperature is either building up to a peak, or heading back down from that highest or lowest temperature. Similarly, during milder weather, or in the spring or fall, design temperatures will generally not be reached. This means that a standard HVAC system will claim too much capacity during the greater part of a day or a year. In recent years, fortunately, HVAC technology has seen advancements in variable-speed and multi-level functioning, which means that systems can adapt their running level to current conditions.
