Three people have died from the disease outbreak, and more than 20 have been hospitalized, according to the latest data from CNN.

With over 75,000 square feet of fabrication space, cutting-edge technology, and a “Care First” safety culture that prioritizes both physical and mental well-being, Arden’s success is not just measured in projects completed—but in the trust earned across generations of clients and partners.

One of the most powerful parts of the trip was witnessing how personal stories and local successes resonate with policymakers. Whether it was a community's struggle with water quality or the adoption of cutting-edge conservation practices, these conversations helped bridge the gap between policy and lived experience.

One concept that’s getting increasing attention among HVAC engineers is “resilient design.” It refers to approaches that - ideally - allow systems to remain operational under very abnormal conditions, or minimize effects that could cause major damage to systems when and if they are otherwise rendered inoperative.

If a customer complains about an air conditioning odor, mention bacteria in condensate drain pans and lines, which is bacterial zoogloea. It thrives in dark, moist, warm settings and can infest the indoor evaporator coil in extreme neglect. The bacteria feed on dust and organic matter not caught by filters.

In a hydronic snow and ice melting (SIM) system, warm water/glycol circulates through pipes embedded in concrete slabs to melt snow and ice above. With sensors, the system automatically activates based on temperature and moisture, effectively melting snow on contact by evaporating it or directing water to drains.

As radiant heating and cooling systems continue to grow in popularity for their superior comfort, energy efficiency, and quiet operation, the importance of proper system installation cannot be overstated. A poorly installed system—no matter how advanced its components—can fall short of expectations, leading to hot and cold spots, energy waste, or costly callbacks.

Too many plumbers overlook the opportunities presented by home and garden shows. Attendance at shows has been increasing every year since the pandemic. Up to 90% of attendees are homeowners. Attendees are typically 35-64 years old and affluent. They attend the show because they want to make improvements in their homes and yards.

The Radiant Professionals Alliance (RPA) provides superior comprehensive educational activities and innovative product awareness. This was evident at the 2025 AHR conference held in Orlando Florida. The RPA hosted eight sessions providing education to professionals and students. From the eight sessions, I would like to highlight five that deal with industry patterns, installation practices and innovative design.

Radiant heating and cooling systems integrated with geothermal ground source heat pumps (GSHPs) offer an energy-efficient, comfortable, and sustainable approach to indoor climate control. This combined system leverages the stable temperatures of the Earth to provide heating and cooling through radiant surfaces, most commonly on floors but also on walls or ceilings.
