Virginia Climate Data

We offer an Virginia Manual J for $79 in 4-6 hours.  We can also offer Virginia Manual S $79 and Virginia Manual D $99.

Below is a collection of Virginia Climate Data and outdoor design conditions. We included an Virginia state average of each category at the bottom of the Manual J climate data table. We created this to allow an easy to use free resource for Manual J professionals to use on jobsites, in the field, and while calculating Manual J heat loss and heat gain reports. If you have a custom set of data from Virginia we would consider adding to the Virginia Climate Data table simply email it to

We can also create a Manual J using climate data from the tables below. Email pdf plans, jobsite address, and square footage to and we will get your Virginia Manual J taken care of.
