Trusted by clients all around the US, Mexico, and Canada

Great experience with Load Calcs. Super fast response and turnaround time followed with one on one attention. Please don't take the HVAC companies rule of thumb recommendation. Educate yourself and get the facts with a certified Manual J calculation. I highly recommend and will use again!
Mia Betty
I was in a bind and contacted Load Calcs on Saturday to complete HVAC load calculations that I needed on Monday morning for a project in Washington DC. They did a wonderful job and worked through the tough DC guidelines. I worked with Scott and he saw the project all the way through until the permit was issued. I would highly recommend this company and will use them in the future.
Timothy Goodman
We needed a load calculation done asap and were recommended to Scott by a friend. He was able to do a load calculation for us in a single day despite all the work he had on top. Thanks for the hard work Scott. We have a couple of more floor plans coming your way!
