HVAC contractors can incorporate a variety of best practices to ensure fleet vehicles are kept running as much as possible.

Add “increased risk of theft” to the growing list of concerns HVAC contractors face as they grapple with a shortage of supplies and equipment. Both HVAC equipment and service vehicles prove prime targets for thieves.

It goes without saying that HVAC work shifts with the seasons. But did you know that the same mentality can apply to your company vehicles?

Since the COVID-19 pandemic struck nearly three years ago, automobile manufacturers have had trouble getting many of the parts — computer chips especially — required to assemble the vans and trucks that field-service businesses use daily.

Having the right fleet management solution can increase employee accountability, efficiency, safety, and grow an HVAC company.

With each passing year, rooftop system developers find new ways to improve this staple piece of HVAC commercial equipment.

Packaged rooftop units are the workhorses of the commercial market, providing cooling to approximately 60% of U.S. commercial building floor area.

This product line is designed for continuous gas monitoring in multiple application settings.

Refrigerant leaks in HVACR equipment – particularly commercial refrigeration systems -- are a significant problem.

According to the Centers for Disease Control (CDC), accidental CO poisoning is the cause of approximately 50,000 emergency room visits and more than 400 deaths each year in the U.S.

While servicing equipment, technicians should be on the lookout for sources of potential future leaks, as well as follow good service practices to prevent creating leaks.

Since A2L refrigerants are designated as mildly flammable, safety features like refrigerant detection systems (RDSs) are being incorporated into new residential/light commercial ducted split systems that contain more than 4 pounds of A2L refrigerant. Here’s what HVAC technicians need to know about installing those RDS in the field.

Supermarkets and grocery stores are facing challenging times as the $1.2 trillion annual sector strives to maintain its relevancy in a sea of change.

Many end users, as well as refrigeration engineers and contractors, attended Food Marketing Institute’s (FMI’s) 2018 Energy & Store Development Conference in Atlanta, looking for advice on how to respond to these trends.

How do refrigeration products continue to spread through everyday life, and what could be in store for the grocery sector in particular?

According to the Environmental Protection Agency (EPA), a typical food retail store leaks an estimated 25 percent of refrigerant, or approximately 1,000 pounds, annually.

When installing or repairing a refrigeration system, technicians should look for opportunities to slightly modify the system (without changing its design) to make it more serviceable.

Store owners and managers are always looking for ways to lower operating expenses, and their refrigeration systems can be a good place to start.

As refrigerant regulations grow more stringent, manufacturers are beginning to offer new refrigeration architectures that utilize low-GWP refrigerants.

Grocers are becoming more vigilant in keeping their refrigeration equipment as clean as possible.

EPA recently expanded its list of acceptable refrigerant substitutes for new refrigeration equipment to include R-471A and R-515B.

At the AHR Expo, manufacturers displayed their latest commercial refrigeration equipment, which included condensing units, components, controls, and other solutions.

The Raphael Rooms in the Vatican are universally known as one of the greatest works of art ever created. During a typical summer, temperatures in Rome can soar as high as 104°F. So the decision to install air conditioning in the Raphael Rooms for the first time ever was an easy one.

In the latest episode of The NEWSMakers podcast, Kyle Gargaro, editorial director for The ACHR NEWS, talks to Michael Kane, president of UEi Test Instruments.

Companies that deal in surplus HVAC equipment are seeing business opportunities in the new U.S. DOE energy efficiency minimums for single-phase residential air-conditioners.

Sean Foster will oversee the distribution sales team responsible for expanding LG’s market share in the residential and light commercial HVAC sectors.

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

Andy Kelso was named COO; Shane Lawrence, CFO; Brinnon Williams, vice president of residential business; and David Archer, vice president of commercial business.

Installing air conditioning in prisons is different than a regular commercial install, and it’s important to know the difference.

Don Kuhl, a U.S. Air Force veteran and civil servant, secured the most public votes and won an a/c unit in the giveaway, which honors the sacrifices of local veterans, active-duty service members, and their families.

The Endeavor Line provides tech-savvy and environmentally mindful consumers like the Horwitzes with smart home compatibility and sustainable features.

Increased cooling capacities, remote monitoring technology, and the need for backup units are all part of the mix in the portable a/c market, experts say.

A new survey released by Daikin studied the opinions and habits of more than 1,200 people from 12 cities across the globe when it comes to their a/c systems.

Since its inception, air conditioning has saved lives and driven technological innovation – take a deep dive into its transformative role.

Evaporative cooling is growing in demand as cooling needs are expanding.

The cooling towers located on the roof of Granite Tower in Denver were meant to last 20 years. But at nearly 40 years, the cooling towers and fluid coolers were well past their life expectancy.

Renewable energy enthusiasts now have reason to celebrate: EVAPCO offers a solar-powered evaporative cooling tower. The SUN cooling tower is paired with PV panels to dramatically reduce energy consumption.  

A product round-up of chillers on the market.

Although evaporative cooling is great at saving energy, it does consume some water, but the benefits on energy savings outweigh the water usage, which in some places is a scarce resource.

Polymer elements in cooling towers — or entire towers made of composite materials, like Fiber Reinforced Polymer (FRP) — can reduce the weight by up to 50%.
