Heat Load Calculations

If you are installing a new HVAC system, proper design and installation is essential for efficiency and functioning. Determining heat load calculations is a necessary but often overlooked method to ensure efficient air management. Absolute Comfort Heating and Air Conditioning is the full-service HVAC company that understands the importance of heat load calculations when installing new HVAC systems.

WHAT ARE HEAT LOAD CALCULATIONS?

Every building gains and loses heat from various sources, internal and external. Heat load calculations analyze the effects of these sources on the building’s summer heat gain and winter heat loss. To cool your home or business, conditioned air output must be greater than the heat load. Accurate heat load calculation will find the most efficient HVAC capacity for your specific home and comfort needs. Considerations when calculating your home’s heat load include:
  • The number of occupants
  • Interior lighting and appliances
  • Number, size and location of windows
  • Building envelope, such as your home’s construction
  • Thermal envelope, such as insulation
Additionally, other building and environmental factors influence heat gain, such as landscaping, shade, location, and even the direction your home faces.

AIR CONDITIONER CONTRACTORS OF AMERICA (ACCA) MANUAL J CALCULATIONS

To standardize air conditioning sizing and installation, the Air Conditioner Contractors of America (ACCA) developed “Manual J / S / T / D”. Each letter specifies protocols for design and installation. The ACCA designed Manual J specifically to discourage “rule-of-thumb” decisions that often result in over-sizing, over-paying, and an under-performing system. Since 2006, International Residential Codes require ACCA Manual protocols. Still, few HVAC companies are willing take the time and effort to make heat load calculations. Absolute Comfort Heating and Air Conditioning uses the most up-to-date software to get exact heat load calculations.
