When you’re considering or embarking on plans for HVAC installation, HVAC design should be top of mind. Correctly sized and designed HVAC and duct systems allow you to better control your home’s climate, leading to a more comfortable life. Manuals J, S, and D are calculations that are crucial to your HVAC design process. Manual J is the calculation determining how much heating and cooling your individual home requires based on the amount of heat it loses or gains when battling cold and hot outside temperatures, respectively. Manual S takes the results from Manual J and determines what equipment size would be appropriate for your HVAC system, along with its optimal heating and cooling capacity. Manual D uses the results from both Manuals J and S to figure out the right size and design of your ductwork. Between these three, you’ll end up with a system that is adequately able to alter your home’s indoor temperature, reduce the humidity levels effectively, and get the right amount of air through your vents into each room of your house.
