How can we help?

If you own or operate an HVAC company, I am willing to bet you have to wear several hats...
Service Tech, Installer, Supervisor, HR, Accountant, Payroll, Designer.... Maybe even more! While we can't help with most of these, we can help take the LOAD of your load calculations off your shoulders.
Many states require an ACCA Manual J load calculation be ran prior to beginning any HVAC System installation. And many municipalities require a Manual J, D, and S when applying for a permit. You may also be required to keep that load on file for several years and make it available to the homeowner or builder.

Instead of wasting your valuable time sitting at a desk running loads, when you can be running your company,
Give Man J Design Services, LLC a call.
Affordable and easy to calculate pricing that you can easily figure into every estimate.
In most cases, less than 24 hour turn around time.
