The HVAC and refrigeration industry is undergoing a major transition with the phase-down of high-global warming potential (GWP) refrigerants. In 2025, new regulations will require businesses to shift towards A2L refrigerants, a new class of low-GWP, mildly flammable refrigerants designed to comply with environmental standards while maintaining energy efficiency. 

The HVAC industry is undergoing significant regulatory changes as governments and industry leaders push for greater energy efficiency, reduced environmental impact, and improved system performance. As we move into 2025, new regulations will impact equipment manufacturers, contractors, and building owners, shaping the way HVAC systems are designed, installed, and maintained. 

Refrigeration systems are essential in industries like food processing, pharmaceuticals, and manufacturing. However, they are also among the most energy-intensive systems in operation. The good news is that modern refrigeration systems now incorporate heat recovery technology to repurpose waste heat, significantly improving energy efficiency and reducing operational costs. 

As industries and governments prioritize climate action, decarbonizing buildings has become a key focus in reducing global greenhouse gas (GHG) emissions. According to the U.S. Department of Energy, buildings account for approximately 40% of total energy use in the United States, with HVAC and refrigeration systems making up a significant portion of that energy demand. Transitioning these systems to greener technologies is essential to achieving carbon neutrality. 

Maintaining a healthy indoor environment while keeping energy costs in check is a challenge for many commercial and industrial facilities. One effective solution is the Energy Recovery Ventilator (ERV), a system designed to improve indoor air quality while reducing energy consumption. ERVs are becoming an essential component of modern HVAC systems, especially in buildings aiming to balance ventilation needs with sustainability goals. 

Cold storage facilities are critical for industries like food processing, pharmaceuticals, and logistics, but they are also among the most energy-intensive operations. Optimizing energy efficiency in these facilities not only reduces operational costs but also contributes to sustainability goals. Here’s how you can optimize your cold storage facility for maximum energy efficiency.

The HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) industry is at the forefront of a green revolution. As global priorities shift toward energy conservation and sustainability, HVAC/R professionals and manufacturers are embracing innovative solutions to reduce environmental impact while meeting the demands of rising energy costs, evolving government policies, and customer expectations. 

As the clock ticks closer to 2025, Boston’s Building Emissions Reduction and Disclosure Ordinance (BERDO 2.0) is top of mind for building owners and managers overseeing properties over 35,000 square feet. This ambitious local law aims to reduce greenhouse gas (GHG) emissions and tackle air pollution, paving the way for a greener Boston. Failure to comply could result in hefty fines, so preparation is key. 

Chillers are a cornerstone of many commercial and industrial operations, responsible for providing efficient cooling to processes, equipment, and spaces. However, like all mechanical systems, chillers have a finite lifespan and knowing when to replace your unit can save you significant money, time, and headaches. Waiting too long can lead to higher energy bills, frequent breakdowns, and reduced efficiency, while upgrading at the right time ensures reliable operation and long-term savings. 

Ice skating rinks are unique environments that require precise climate control to maintain optimal ice quality, structural integrity, and the comfort and safety of skaters and spectators. One critical aspect of this control is dehumidification. Without proper humidity management, ice rinks face a host of problems, from foggy arenas to structural damage and unsafe skating conditions. 

Heat pumps are becoming an increasingly popular choice for heating and cooling homes and businesses due to their energy efficiency and versatility. However, despite their growing adoption, many misconceptions still surround heat pumps, leaving potential users uncertain about whether they’re the right choice. In this blog post, we’ll address and debunk some of the most common heat pump myths, giving you the information you need to make an informed decision. 

Air filters are the first line of defense for your HVAC system. They trap dust, dirt, allergens, and other particles from the air before it enters the system.

In New England’s cold climate, HVAC systems must be designed to withstand harsh winters while operating efficiently. One critical component of cold-weather HVAC design is the use of glycol in hydronic systems to prevent pipe freezing. Glycol plays a pivotal role in protecting equipment, ensuring longevity, and maintaining efficiency, but it comes with specific considerations that need to be addressed during system design, installation, and maintenance. 

Energy efficiency is a top priority for homeowners and businesses looking to reduce their energy costs and minimize their environmental footprint. While all major HVAC manufacturers offer energy-efficient product lines, understanding the key features that contribute to efficiency will help you make an informed decision when choosing the best HVAC unit for your needs. This article will guide you through the most important elements to consider when evaluating energy-efficient HVAC systems. 

Decarbonization is an urgent goal for both commercial and industrial sectors, particularly as energy-intensive industries and large building complexes are under increasing pressure to reduce their carbon emissions. In the Northeast, ambitious decarbonization goals are driving investments in clean energy, energy efficiency, and sustainable technologies. In this deep dive, we’ll explore how advancements in technology and evolving government policies are shaping the path to decarbonization in the Northeast and how these efforts impact both commercial and industrial sectors. 

In today’s world, businesses are increasingly focused on finding more sustainable and environmentally friendly solutions for their refrigeration needs. CO2 (R-744) is gaining traction as one of the leading refrigerants due to its low environmental impact and high efficiency. But what makes CO2 stand out among other refrigerants? Let’s explore seven key facts that make CO2 a future-proof refrigerant for commercial and industrial applications. 

Ammonia refrigeration systems are widely recognized for their efficiency and environmental benefits, but they are not without challenges. One of the common issues that can arise over time is water contamination in closed-circuit systems. While this might not sound like a major concern, the accumulation of water in ammonia refrigeration systems can lead to significant operational problems and efficiency losses if not properly addressed. 

As energy costs continue to rise and businesses and homeowners seek more efficient ways to manage their energy usage, smart thermostats have emerged as a popular solution. These intelligent devices offer more than just convenience—they can help save money by optimizing heating and cooling systems, reducing energy waste, and allowing for more precise control of indoor environments. 

Ammonia refrigeration systems are highly efficient and widely used in industrial settings such as food processing, cold storage, and manufacturing. However, while ammonia offers many advantages as a refrigerant, including cost efficiency and environmental benefits, it also poses potential safety hazards due to its toxicity and flammability. Therefore, it is critical to have proper ventilation and detection systems in place to ensure safe operation and protect both employees and the surrounding community. 

What Are A2L Refrigerants? A2L refrigerants are a class of refrigerants that are mildly flammable and have a lower Global Warming Potential (GWP) compared to traditional refrigerants like HFCs (hydrofluorocarbons). Examples of A2L refrigerants include R-32 and R-454B, which are increasingly being used as replacements for higher-GWP refrigerants such as R-410A.
