Why Is a Manual J and Manual S important for your Construction Project?
On this version of the Reschexpert blog we want to discuss with you why it is essential to have a Manual J and Manual S in addition to a Rescheck on a construction project.
Whether you are building a new construction, addition, or alteration having the information provided on a Manual j or Manual s can prove essential. A manual j measures your homes heat gain and loss and the manual s takes this heat gain and loss information and translates it into the size of your actual unit.
Both Manual J and Manual S operate using your local climate data. So the weather in the closest proximity to your jobsite is used to create your energy usage and then ultimately select the size of your HVAC units.
Having a Manual J and Manual S can take a lot of the guess work and “rule of thumb” out of the HVAC process. By having specific calculations the guess work is gone and determining brand, placement, and labor become the more difficult tasks of the installation and estimation of your HVAC system.
A Manual J and Manual S may or may not be required for your actual permit. You would need to ask your building inspector or building department. We do have instances when a client will order the Manual J and Manual S even when it is not required, just to have piece of mind.
Overall having a Manual J or Manual S may or may not benefit your project and the choice to use it may be compulsory or up for debate. In the event that your building permit does require a Manual J or Manual S we can create it for you. Simply email us plans, jobsite address, and square footage to [email protected] and we will get you taken care of.
