Why Heat Loss Calculations Are Important?
Depending on the building or home, a heat loss calculation is essential to designing an HVAC system to accommodate the size, number, and location of air ducts. Heat loss also plays a big part in finding the right size unit to heat and cool a home or business efficiently. So contact our HVAC contractor in Orem, UT.
Calculating Heat loss will help contractors and businesses understand:
- The square footage of space that needs to be cooled
- How hard the unit will have to work to cool or heat a specific space
- Heating and cooling goals for home and business.
Who Should do Heat Loss Calculations?
Builders. Utah Building Codes requires heat loss calculations be submitted when applying for a building permit to ensure that the heating system is properly sized for the house. These calculations also help the builder estimate the cost of the heating system.
Homeowners. Heat calculations enable homeowners to optimize energy conservation investments.
Heating system professionals. The Professionals at JP Cooling and Heating use heat loss calculations to correctly size the heating equipment for the job.
If you are ready to start building your dream home or are adding on to your existing home call JP Cooling and Heating at 801-420-1979 for these vital money saving reports.
Key Parts of Heat Load Calculation
Manual J. The Manual J calculation is a formula that identifies the HVAC capacity of a building. It might also be called an HVAC load calculation because it describes the size of equipment needed to heat and cool a building. The primary users of the Manual J calculation are HVAC installers, technicians and contractors.
Manual J is the first step in the design process of a new HVAC system and analyzes a complex series of calculations, or load calculations, used to determine:
- Total amount of heat that is lost through the exterior of a home during the cooler months
- Total amount of heat that is gained through the exterior of a home during the warmer months
Load Calculations Analyze Certain Characteristics Of A Home Such As:
- Walls
- Floors (square footage)
- Ceilings
- Size and Placement of Rooms
- Number of Doors and Windows
- Amount of Insulation
And It Takes Into Account Other Important Factors Such As:
- Number of Occupants
- Geographic Location
- Orientation to the Sun
- Structure Tightness
- Duct Leakage

Manual S. Once a Manual J load calculation has been completed a Manual S procedure is used for covering the proper equipment sizing recommendations. Selection is based on performance criteria such as:
- Equipment’s total capacity to remove heat and moisture from the air
- How much total air, and at what static pressure the system can operate under
Manual D. (Duct Design) Manual D is the ACCA (Air Conditioning Contractors of America) method used to determine the overall duct layout and sizes in HVAC design. Once you know how much A/C you need, what equipment you have, and how you will distribute the air, you can design the duct system. Poor ductwork design can seriously affect your comfort and indoor air quality. Ducts that are small in size make your HVAC system work harder to keep your home at the desired temperature. If your duct size is big, the velocity of air gets compromised. It means you will not be able to feel the air flowing through the air vents. Even you can contact us for the new AC system Orem UT.
