Technical Tips

After years of development, a new safety standard from ASHRAE has been published. Read this members-only blog to learn all about the new safety standards.

The reversing valve is responsible for moving temperatures around. Read this blog to learn how to efficiently troubleshoot your reversing valve.

Finding the correct pressure drop is often made up rather than looked up. Ed Janowiak explains this issue and offers a solution in this blog.

In the summer, working outside can pose a serious threat. Read this blog to learn how to stay safe and cool when working outside during the summer.

The ACCA Duct Slide Rule allows contractors and technicians to calculate the size of a system’s duct with friction rate. Read more at this blog.

measureQuick® gives you an advantage over your competition when it comes to equipment installations. Read more about measureQuick at this blog.

When the weather is this hot, HVAC technicians will be called to serve AC units quite frequently. Read this blog to see the forecast and plan accordingly.

This introduction to static pressure discusses the basic elements of vital measurements and how they can be used. You can quickly identify HVACR equipment in new or like-new condition with airflow problems. This can save you a warranty call for a burned-out motor or maybe a callback for a poorly performing duct system (or incorrect fan speed setting).

Being consistent in your brand builds trust and improves efficiency. Consistency is essential, especially when running your maintenance calls for your clients. It’s critical that you establish trust with clients, which can lead to better customer service, improved client relations, and less customer churn. This article discusses the importance of consistency when performing HVAC maintenance and some things you can do to build better consistency.

New research shows that when a common antiseptic is applied to filters… they can KILL COVID-19! But, upon looking at the research, questions emerged.

Recently, the International Energy Conservation Code (IECC) Committee approved proposals submitted by ACCA for public comment. The proposals add the option of conducting a duct airflow balancing procedure per ACCA 5 QI, as well as adding ACCA Manual D, to ensure a more efficient HVAC thermal distribution system.

Over the next few months, Ed Janowiak will cover topics about measuring airflow, focusing on airflow measurements and how important it is to follow “the rules.” This month, he’s covering static pressure measurement.
