Enertech Global LLC and Palmetto have launched a 10-year residential geothermal lease with no upfront cost, fixed monthly payments, and full maintenance and warranty coverage. The program is made possible by the One Big Beautiful Bill Act of 2025, which allows commercial leasing companies to claim federal tax credits under IRS Section 48 for residential geothermal systems.
Canada will invest $2 billion over eight years to retrofit one million homes with electric heat pumps, offering rebates of up to $10,000 for below-median-income households and $2,000 for other eligible households. The program targets roughly 820,000 households and will be rolled out in immediate consultation with the HVAC industry.
In early November 2026, new editions and draft technical rules for HVAC and building services engineering were published. The package covers operational requirements for CO₂ and A1-class refrigerant installations, safety of displacement compressors, and energy efficiency of cold stores.
The Canadian Board for Harmonized Construction Codes is accepting public comments until Dec. 21 on proposed technical amendments to the 2025 editions of four national codes covering building, fire, energy, and plumbing regulations.
Three Gree compressor technologies for residential central air conditioning and heat pumps have passed independent expert review and been recognized at the international advanced level. The solutions address key challenges in cooling and heating for residential central AC and heat pump systems.
Optimized air movement in commercial refrigeration can deliver up to 7% energy savings, equivalent to roughly 3.64 TWh annually across the EU 27. Daniel Hofmann of Nidec Global Appliance (Embraco) explains how integrated fan pack design—combining EC motors, aerodynamic blades, and shrouds—addresses the performance bottleneck that has shifted from compressors to ventilation.
Everest Refrigeration and Embraco have introduced the Plus Inverter+, the first water purifier in Brazil to use inverter compressor technology. Built around a sealed unit with Embraco's FMS variable-speed compressor and R600a refrigerant, the product cuts energy consumption by 70% compared to Everest's conventional Plus line.
An evaporative condensator uses water evaporation to lower the condensation temperature in industrial refrigeration circuits, reducing energy consumption by more than 10% compared to air-cooled systems. The article covers the working principle, performance factors, and key criteria for selecting this equipment.
Polair has introduced the Future series of refrigerated cabinets, unifying all temperature variants in a single monolithic body with 61 mm walls and adopting cassette (modular) units for the refrigerant circuit. The reduced overall depth increases storage volume on the same floor area. The series is now available for order.
MIAL's MUF 1200 clamp-on ultrasonic flow/BTU meter, rated at 1% accuracy, enables digital monitoring of chilled-water and district-cooling systems by mounting transducers externally on existing pipes. The approach targets India's large installed base of operational HVAC installations where retrofitting inline meters would require draining, cutting and shutdowns.
Pascal, a startup spun out of Harvard University research, has completed a barocaloric-effect refrigerator prototype and is preparing to install it at an unnamed multinational beverage producer. The company announced it raised approximately $9.3 million to advance the technology.
Merak has become the only rail HVAC supplier offering serial production units on both natural refrigerants — CO2 (R744) and propane (R290). According to the company, thousands of Greenair heat pumps have been installed worldwide, reducing energy consumption by at least 30% compared to resistive heating.
