I will do manual j and s load calculations

we do not work with home SF, we consider residential A/C systems. The system's biggest system that is possible to install is 5 tons, it could be useful for 2000 through 2500SF depending on the USA zone where will be installed. That means a Manual J and S for 2500 SF could be $65.

More than 20 years of experience designing and installing residential air conditioning systems support our designs. we consider if is the owner or an HVAC contractor or a General Contractor who is requesting the manual j because the opinion or needs of each one can be different.

Our duct design could be only using duct board, flex, or some combination of both of them.

ACCA - approved software "wrightsoft" is our tool to design our heat load and duct layout, you need to send us the architectural floor plan with all measurements, and the kind of construction material of the roof and walls with their R insulation.

Subsequent consultations regarding the plans you sent may also be required.
