LEARN MORE ABOUT HVAC MISCONCEPTIONS

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.

  • 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.

  • 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!
