Hi, my name is Howard, and welcome to my blog. Through the years, I have spent a lot of time studying, researching and learning about HVAC systems. While searching online, I have been unable to find lots of technical information so I decided to make a blog about HVAC questions and answers. In this blog, I plan to explore everything from how to build an HVAC system from scratch, to how to make your current system more effective, to how to clean your system, to how to hire the best contractors and more. If you have a technical question or concern, please explore this blog and learn as much as possible. Thanks for reading!
