Benefits of getting an Calculation Software

Equipment cost
You’ll pay more for higher-capacity equipment, so by sizing your equipment correctly by performing a load calculation you can save on the up-front cost
Health and comfort
When your equipment is too large for your home it will cause it to short cycle, which can cause temperature and humidity control problems that adversely affect comfort and lead to health issues like mold growth
Operating costs
HVAC equipment that is properly sized heats and cools your living space more efficiently, so you avoid unnecessary energy waste that inflates your operating costs
Equipment longevity
Short cycling is not only inefficient, it also puts wear and strain on your HVAC components that can shorten their expected lifespan
