Hello
Aaron kindly brought your project to my attention as I currently write 10 articles per month for an American supplier and installer of heating, ventilation and air conditioning units. I am able to write in American or British English, depending on what you would prefer.
Your project description is quite brief, so I would ask if your intention is to provide the information for each HVAC unit and the requirement is to reword that text to be more original and to avoid Google penalties for duplicate content.
Finally, you have only stipulated 'Content Writing' as a skill so my profile only shows 24 projects, all completed at a 5* rating. However you will see from my full profile that I have over 700 writing-related projects completed, all again at a 5* rating, and all delivered 100% on time and on budget, so I can guarantee you both quality and reliability.
I would be delighted to discuss the full extent of this project with you further.
David Dundas
