3 Heating and Cooling Loads That Every Homeowner Should Know

3 Heating and Cooling Loads That Every Homeowner Should Know

Just as you wouldn’t buy yourself a pair of shoes that are twice your size to give you extra wiggle room, your home shouldn’t have an HVAC system that’s the incorrect size or capacity. As you shop for an HVAC unit, it’s wise to have a contractor calculate your home’s heating and cooling loads so you can make an educated decision regarding the appliance that’s right for you.

Heating and Cooling Loads Explained

Load refers to the amount of warm or cool air a building or space needs to maintain ideal temperatures and relative humidity levels. To calculate a home’s load, a contractor takes into consideration several factors, such as square footage, the direction the house faces, heat gain and loss, architectural style, number of levels, insulation type and the number of windows.

Contractors use load calculations to determine how much capacity an HVAC system needs to keep your home comfortable without wasting energy or experiencing unnecessary wear and tear.

Types of Heating and Cooling Loads

Following are the three types of heating and cooling loads:

  • Design load: Contractors measure design loads in tons. Design loads refer to an HVAC unit’s maximum capacity, or the amount of warm and cool air the system produces in winter and summer based on design conditions, including the recommended indoor design temperatures.
  • Extreme load: Extreme loads refer to extreme hot and cold weather, which place extra load requirements on HVAC systems. Engineers design HVAC systems with safety measures so they perform well in the event of extreme winter and summer conditions.
  • Part load: Engineers make HVAC systems so they accommodate design temperatures throughout the year. When outdoor temperatures don’t meet the design temperatures, a unit only runs at part-load capacity.

When shopping for a new HVAC unit, it’s vital for a contractor to calculate the correct heating and cooling loads to pair you with the right system.
