What is HVAC Load Calculation?
 
How big does a heating or cooling system need to be to keep a home or business comfortable? That's the question that an HVAC load calculation helps to answer. The correct answer helps ensure that a system will be the right fit for your customers in the years to come. By making the move and getting a detailed calculation before the installation of new equipment will also reduce warranty call outs. Getting the answer right is also your best guarantee that a new system will deliver an optimal level of comfort for many years to come which in turn keeps your customers happy and spreading the word of your professional work standards.
 
HVAC System Sizing
HVAC systems are sized according to the amount of heating or cooling that they produce. British thermal units (Btus) are used when measuring the system's output. A single Btu represents the amount of energy needed to raise the temperature of water by one degree. The output capacity of heating and cooling systems are measured in thousands of Btus. Because it takes 12,000 Btus per hour to freeze one ton of water over a 24-hour period, cooling systems typically use the term “ton” to describe the system's output. In general, a ton of cooling is needed for a 1,000 square-foot space.

Factors Considered in HVAC Load Calculations
 
A skilled HVAC technician doesn't only use the square footage of a structure to make a load calculation. Each home or business has individual features that can affect the building's heating and cooling needs. The structure's overall design, construction, level of insulation and orientation to the sun must all be taken into consideration. There's a human factor to consider when calculating heating and cooling loads as well. The number of people that occupy the space as well as their behaviors and schedules also factor into professional load calculations. 
 
HVAC System Size Matters
Oversized systems quickly heat or cool your indoor environment but cycle off again just as quickly. This not only results in annoying shifts of temperature but strains the system's equipment as well. Short cycles don't give the systems time to circulate the air properly, leading to a build-up of humidity that as damaging to equipping as it uncomfortable for the building's occupants. Undersized systems can quickly wear themselves out by continuous operation as they strive to reach the desired temperature.


When conducting a load calculation on all structures we use an up to
date software in compliance with Manual J to produce the most accurate estimation
of the buildings heating and cooling needs.
