From high-turndown boilers and electrified heat pumps to smarter rooftop units and DOAS systems, this year’s commercial heating lineup combines higher efficiency with easier installation and service.
Residential credits are set to sunset, but commercial geothermal continues to gain momentum thanks to not-yet-expiring tax incentives, innovation, and maturing tech. For HVACR contractors, the next wave of geothermal growth hinges on training and design expertise.
A federal court has upheld the Department of Energy’s furnace efficiency rule, requiring all new residential furnaces manufactured after 2028 to be 15% more efficient than today’s models. The DOE says the move will save consumers an average of $350 over the life of their equipment while cutting emissions equivalent to shutting down two dozen gas power plants.
Commercial demand for HVAC equipment grew in Q3, while residential sales fell, due to consumer uncertainty, cooler weather, and the lingering effects of the refrigerant transition.
EPA’s proposed refrigerant rule revisions would extend compliance deadlines and raise GWP limits. Industry groups are divided between supporting flexibility and warning of confusion and delayed transitions.
In this video, Ben Kromer, HVACR service manager at Rolls Mechanical, talks about some smaller steps and some bigger measures that can maximize efficiency with RTUs.
