In this world, we often find ourselves at the mercy of those whom we assume know more than us. This can cost us time, money, energy, and even our health.

Heating and Air Conditioning systems run on simple principles and ignorance of those can cost you more than you can dream! This book gives you the tools to empower yourself so you will never again have to blindly trust what others are telling you and you can troubleshoot minor problems yourself.

  • 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.

  • This is the second time I’ve used ProCalcs and already have a third project I want to engage with them on eventually. I keep coming back because they’re responsive; they have deep technical knowledge; and they take time to ensure the design they provide is going to fit into the structure of the building the system is being designed for - reducing headaches later. During the process I find them to be very responsive. Even if the answer isn’t provided immediately, they acknowledge receipt to let you know they’re looking into it - which gives me huge piece of mind. Overall, one of the best services providers I’ve had the pleasure of working with in the home remodeling space. Highly recommended!

  • ProCalcs did the HVAC plans for a new renovation of my house and the results were exceptional! They did all of the load calculations, design, equipment recommendations, etc. Everything anyone would need to permit and install an HVAC system. My house is broken up into multiple levels and areas and the plans came out great! My brother-in law is in the HVAC industry and said these were the best plans he's ever seen. Highly recommend this company and well worth the expense. They were also super responsive and friendly. Thanks so much!

  • Used ProCalcs to design the HVAC system for a new residential build. They responded quickly to my web inquiry and let me know what the process would be like. I liked what I heard and thought the pricing structure was very reasonable. I engaged them for the project and it was a smooth and quick process. They did what so many businesses fail at.....they ACUATLLY DID what they said they would do, when they said they would do it. I got professional service and professional and detailed documents. Exactly what I needed and paid for. I highly recommend their company, their people and their services. Thank again to the staff there!

  • ProCalcs LLC is the best. They work as hard as you do and actually care about your project. They are not your typical engineer or architect who gives you incomplete drawings just to get paid. They actually try to pass plan review the first time! And I have always received my permits without needing resubmittals from ProCalcs. That saves me time and money. Use them! You will not be disappointed.

  • Could not recommend this company and their staff more. Response time , prompt communications , and professional work . while Tom was excellent at the initial phase and overall supervision, Richard was excellent in developing the overall design and specification of an elaborate new HVAC system and followed my guidelines and parameters to the T !! I wouldnt hesitate to work with Procalc again.
