Manual J-D-S

Developed by the Air Conditioning Contractor’s Association (ACCA), a Manual J calculation is the only method approved by all equipment manufacturers, the Department of Energy, and the EPA. The ACCA’s Manual D specifies the overall detailed duct layout of the home, including the sizing of each individual duct and register and its placement within each room. Manual S is the ACCA’s standard for equipment selection based on calculated design loads.

All too often, whole HVAC central systems along with the accompanying duct systems are created using “experienced guesses” in lieu of the proper Manual J, Manual S, and Manual D methodologies. As a sign of our commitment to excellent building design, Diversified Energy provides these detailed calculations, regardless of whether the consumer contracts their HVAC installation through our company. Fees are determined by the size and complexity of the floor plan.

Be wary of HVAC contractors in Louisiana that don’t comply with the ACCA’s standards.

Diversified Energy offers Manual J, Manual D, and Manual S calculation services to our clients across the greater New Orleans region. Optimize your HVAC design and get the best performing HVAC system. Contact Us Today!

Niki Aguillard and her crew came out to my house and did a fantastic job! They texted me what time they would arrive and they were on time. They made... sure every crack was sealed in my house and even put door sliders on the doors to keep the air from flowing in. They completely insulated the attic. They were very friendly and kind overall did an amazing job I’m very pleased with how they went over and beyond to ease every concern I had and I really appreciate their hard work. Would definitely recommend Diversified Energy “Plug into Comfort”read more

First off these are some friendly and professional people! They came in to our home and had nothing but respect and explained things in a way that... was more family/friend based than technical. BIG shout out to Mike and Ryan for the amazing help and work! They tested the house and did all the checks as well as made sure we had stuff in place. They hooked us up with a great light package that should help our energy use as well as lighting needs. Everything is top notch and amazing customer service!read more
