I will provide permit ready manual j heating and cooling load calculations
Structured HVAC engineering
About this Gig
Need accurate HVAC sizing for a residential project, but your contractor, building department, or permit reviewer requires professional load calculations?
I provide permit-ready Manual J heating and cooling load calculations designed to give you clear, defensible HVAC sizing for your project. I can prepare room-by-room and block load calculations for new construction, additions, remodels, replacements, and residential HVAC projects.
You will receive properly organized calculations showing heating load, cooling load, room-by-room loads, design conditions, equipment sizing guidance, and supporting HVAC documentation based on the project information provided.
I understand the real problem: an incorrect HVAC load can lead to oversized equipment, poor comfort, unnecessary energy costs, contractor confusion, or permit delays. My approach is focused on accurate calculations and documentation that are practical for contractors, homeowners, designers, and permit submissions.
Clients keep coming back because I pay attention to the project details, communicate clearly, and deliver work that is organized and easy to review.

FAQ
What information do you need to start the Manual J calculation?
I need the architectural floor plans, project location, conditioned floor area, construction details, window/door information, and available HVAC requirements. I review the inputs before calculation to identify missing or conflicting data.
Will the calculations include room-by-room heating and cooling loads?
Yes. I provide room-by-room heating and cooling loads, along with the applicable total/block loads, so HVAC sizing is based on calculated demand rather than rule-of-thumb estimates.
Can you prepare the calculations for a permit submission?
Yes. I provide a professionally organized, permit-oriented Manual J calculation package. I also follow the project information and applicable requirements provided by the client. Final acceptance is determined by the local authority having jurisdiction (AHJ).
