New window units are quiet and efficient, and HVAC contractors may want to consider offering them to customers who need them on an emergency – or long-term – basis.

The Gold award in the Refrigeration and Ice Machines category goes to a self-contained refrigeration system for walk-in coolers and freezers that eliminates several of the steps required for a traditional system.

The Gold award goes to a tube cleaner that takes high-speed tube cleaning to new levels and is designed for contractors and facility managers with large tube bundles.

Despite rising costs, consumers remain open to high-end HVAC systems, especially when guided by contractors who emphasize balancing upfront expenses with improved comfort and energy efficiency.

The Gold winner reduces the on-site service call time required to service refrigeration equipment by providing a simple solution that would utilize smartphone and tablet technology to diagnose issues quickly and determine if corrective actions provided resolution for the problems.

With the phasedown of HFCs, there will be a greater demand for reclaimed refrigerants. The problem is, the amount of reclaimed refrigerant being produced is inadequate to meet those demands.

Portable cooling systems work well as temporary solutions and can also serve as long-term options for unconditioned spaces like factories and warehouses.

The HFC phasedown is well underway in the U.S., and we will soon see A2L equipment becoming available, just like in Europe.

Manufacturers are offering low-GWP refrigerant alternatives, as EPA is proposing a 700 GWP limit for most new comfort cooling chillers starting in 2025.
