Admittedly, spring is a perfect time to put such cleaning and maintenance at the top of the to-do list. Condenser and evaporator coils are an integral part of HVAC systems, and one of the quickest and safest ways to maintain them is through a comprehensive coil-cleaning program. Even the best, most expensive system will not reach its optimum performance without proper

New technology finds its niche in rooftop inspections, promotional videos, surveillance, and more Drones are an emerging technology in the U.S. and are just now entering the public conscience. Some of us have read about Amazon’s bold plans to have drones deliver goods or have witnessed friends, family, or strangers operating drones in public parks. Despite their public infancy, drones have shown great potential in HVAC-specific capacities. EYE IN THE SKY Perhaps drones’ most significant HVACR application lies in their ability to inspect rooftop units. Using a drone allows a technician to

WellSpan Gettysburg Hospital was looking to modernize mechanical systems to ensure reliability of critical patient-care functions. Constructed in 1921, WellSpan Gettysburg Hospital in Gettysburg, Pa., has undergone a number of changes over the years. According to Joe Lehigh of the facility’s engineering team, the most recent were made chiefly to improve hospital operations. “The key need was to modernize mechanical systems that would assure reliability of critical patient-care functions,” Lehigh said. “High on the list was cooling equipment that had close ties to operation of our clinical and
