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.

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.

Have used them several times for a lot of load and energy Calcs. Very fast response times!

My experience with ProCals was professional, timely, educational and kind. I'm a 46 yr old woman in charge of a $500k+ project. As we ran into issues with the complexity of our HVAC system design, our original architect outsourced the mechanical calculations and drawings to ProCals. The City of Doral had rejected the plans and I didn't understand all the codes on the remarks. At this point, time & money on my mind, I was very anxious. Ashley was the first one we spoke with. She was listen to my frustration then took time to go through each of the remarks and explain. There were about 10 of them. After the changes, my architect and I were able to resubmit the plans and they got approved. So construction could finally start. John and Richard were so kind through all of the issues that came during the mechanical installation. Kimberly and Ashley always responded to emails if the guys were not able to right away. We had a few change request charges, but to me surprised, many if them they simply updated. Here are a few changes we had them do. FIRST We could not get the RTU anymore and needed to change the plans again. ---and if I recall correctly, we had them put this one on the plans but by the time we got through City approval. Somehow that unit wasn't available anymore. The units that we could get we had them change the plans to the new units and do all the calculations again. THEN....! We needed to change all the exhaust and returns in the common areas THEN....! We had them change all the the dimensions of the return ducting to allow for the interference of the fire riser, roof, plumbing vents, electrical, sprinkler systems and everything else that is in the face that required are returns to go through. THEN...! The exhaust unit we told him we were getting became unavailable so we call to change the plans again and recalculate again. This pandemic has been very crazy securing parts, things have disappeared, contractors and everything they're going through, he is an owner and managing the project, all of these variables has made this project much crazy than previous projects. So that is SOME of the detail behind why I say My experience with ProCals was professional, timely, educational and kind. I've never met Tom, but he was copied on all communications. So all I can say about Tom is that HE HAS AN AMAZING TEAM. So he MUST be pretty cool at well.

We have used ProCalcs on a few projects now and have enjoyed the team effort. ProCalcs is very responsive and has completed all of our projects on time. All of the staff has been easy to work with. Thank you ProCalcs.
