An NFPA Industry Task Group with ACCA representation has recommended an amendment to the 2023 NEC to exempt ALL outdoor HVACR from having GFCI protection until September 1, 2026.

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.
