Never Replace a Compressor Without Finding Out Why It Failed
Posted on March 19, 2020 by admin in Blog_PostsWhen a compressor fails, it seldom happens due to a defect in the compressor itself. In fact, 90% of compressor failures occur as a direct result of issues found elsewhere in the system. If a new compressor is installed without identifying and fixing the root problem, the new unit will likely fail as well. Loss […]

10 Residential HVAC Airflow Problem Indicators
Posted on March 4, 2020 by admin in Blog_PostsHot and cold spots indicate uneven airflow, lack of airflow, or the infiltration of outside air in the space. Bad design can result in airflow problems. Oftentimes a residential HVAC system can be oversized, thus turning the unit on and off much more frequently with excessive airflow and insufficient humidity. Another example is undersized ductwork […]

Measuring HVAC Airflow and Static Pressure: If You’re Not Collecting Data, You’re Just Guessing
Posted on December 26, 2019 by admin in Blog_PostsSimply replacing HVAC equipment will not correct airflow performance issues. Rather, clearly identifying static pressure problems and correcting ductwork anomalies will. But to find the problems afflicting an HVAC system, you first need to know where to look and how. If you’re not collecting data you’re just guessing. As static pressure increases, airflow will decrease. […]
