Thank you Procalcs for the prompt attention to our needs. we were in need of an Energy calculation, Manual J, and mechanical layout. We provided Procalcs with the brand and model of unit that we wanted to install, and they did the calculations. we needed few corrections from the original documents, and Procalcs did the modification no question ask. Thank you to the team of Procalcs.

Procalcs is fantastic!!! They did a full manual j load calc manual s system calc manual d duct design manual t air flow etc... on my residential new build near Columbus Ohio They did a great job!!!! The entire staff was very professional They responded to my initial inquiry almost immediately and gave a very quick and precise estimate for my job They provided a fantastic duct design and did it in record time!!! My residential new build required two systems due to the square footage Jerson was fantastic on the design and the entire staff was very good about staying in contact with me I received professionally done duct and system layout as well as all of the associated data that my local building department required Could not be happier!!!!! Thanks Procalcs!!!!!!

We switched to this out-of-town Manual J service when our previous provider was backed up and slow. ProCalcs is quick to respond, thorough, and even took the time to "override" and correct the errant findings of a Professional Engineer that reviewed one of our projects, contesting the sizing of the HVAC equipment. Kudos for going over and above on all aspects of product delivery and customer service!

ProCalcs were very helpful with my design and working within the constraints of my project. I had been looking for a good HVAC designer for a while, glad I found ProCalcs. I would highly recommend ProCalcs for any HVAC designing.

Their staff treats each project professionally from a small remodel to an 11k SqFt custom home. They itemize their services and allow you to choose what scope they will perform. The results are well presented and in a very timely manner.

ProCalcs did a great job completing the HVAC design reports for our new home. They were very accommodating to all my questions and changes.

They did an excellent job with energy calculation of new and existing HVAC for proposed home addition

Gave me a manual J, D and S. They responded quickly to my request. I had the results within 4 days. I worked with Sol and she was responsive and thorough and communicated well.

They always do an excellent job. Very fast delivery

The quality of product exceeded my expectations. Value was very fair. I would recommend.
