Commercial cooling equipment manufacturers are introducing HVAC systems that are energy efficient, as well as service friendly for contractors.

A recent survey done by Daikin shows what state leads the globe in a/c usage.

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

Cooling towers offer a proven and cost-effective solution for rejecting heat from condenser water and industrial processes. To maximize the operating cost savings, the fill media must be properly designed and in good condition.

Trane Technologies and Neiman Marcus Group are collaborating to decarbonize the luxury retailer’s footprint through renewable energy, electrification, energy efficiency, and refrigerant management.

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.  

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.

Despite their similar exterior appearance, cooling towers and closed-circuit coolers are very different pieces of equipment with distinct advantages and limitations. This is especially true when determining which option is best suited for a specific cooling application.

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

By splitting the absorption process into two steps, lithium bromide solution concentrations are lower in the system, enabling lower hot water temperatures within the generator, lower hot water flow rates, and the elimination of crystallization risk within the chiller.

A North Carolina-based community college replaces an aging metal-clad cooling tower with a modern HDPE unit, reducing maintenance spending while increasing efficiency.

With a double brood of cicadas forecasted to awaken, now is the time to prepare for how to deal with the mess they will leave behind and the potential damage they can do to equipment.

It was a celebration for Yellow Jacket as the company kicked off its 70th anniversary. In a square booth with a large, lit banner, attendees were invited to explore what the company had produced from 1949 to 2019.

These products work with the Fieldpiece Job Link System App for on-the-go testing and reporting for HVACR electrical tests.

Here are a few ideas that contractor can use to prime the marketing pump for this holiday.

Internet-connected thermostats are gaining wider acceptance in the marketplace. About 30% of residential thermostats in the U.S. and Canada are connected thermostats.

Through the new integration, ecobee thermostat owners who also own Generac home standby generators can easily see the status of the generator and remedy potential issues.

While government incentives, savings in utility bills, word-of-mouth, and increasing popularity have led to homeowner’s increased awareness of smart thermostats, there is still a lot of room in the market for growth.

Thermostat manufacturers say they have the studies to show that the use of their smart, connected thermostats can help homeowners save on their HVAC-related energy costs.

The NEWS’ annual Cooling Showcase has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands. In this issue, we focus on the commercial side of the air conditioning industry.

It’s time again for the Commercial Cooling Showcase. The NEWS’ annual issue has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.

HVAC manufacturers share their latest heating products — including photos, specifications, warranty info, and more — in this detailed showcase.

The rule will effectively ban the sale of non-condensing gas furnaces and, according to the American Gas Association (AGA), will affect 55% of U.S. households.

AHRI launched an interactive US map showing state codes for A2L refrigerants, alongside a video series on low-GWP refrigerant transition.

With more than a trillion dollars designated from the Infrastructure Investment and Jobs Act (IIJA) starting to hit the wider economic field, HVAC contractors and the utility industry should be aware of how to cash in.

In preparing for the refrigerant transition, contractors and distributors should review their inventory and become educated on the regulations.

An HVAC solution was the headliner for an event on Feb. 19 at a 121-year-old building in the nation’s capital named after one of America’s greatest composer-musicians. The event at Duke Ellington School of the Arts demonstrated how stepping beyond traditional non-inverter HVAC systems can preserve a building’s historical architecture, enhance energy efficiencies, minimize noise, and earn design-award accolades.

The equipment in this month’s troubleshooting situation is a split system that has only been in service for two years, but there is a lot of history — several service calls since the equipment was installed, and an on-going complaint that the system just doesn’t keep the ranch-style home comfortable.

With over 1,000 Sunday service attendees and many church activities throughout the week, energy efficiency for the sake of cost savings was critical.

Both commercial facilities and residential domiciles are taking advantage of heating and cooling technology at accelerated rates.

As HVACR technology advances, contractors often find themselves navigating new learning curves on a regular basis. VRF is no exception.

Manufacturers and contractors are working to educate end users about the ways heat pumps work differently from traditional heat sources.

Consumer awareness and opinion of heat pumps are both improving, along with the technology. Manufacturers see a strong market ahead, although some challenges remain.

Kyle Gargaro, editorial director, The ACHR NEWS, traveled to Oklahoma City to talk with Climate Control Group COO Kevin McNamara about the state of the geothermal industry.

To help the industry better promote geothermal heat pump technology, it first needs to have an understanding of exactly what is going on during its heating and cooling process.

Four core components work together to control when refrigerant is absorbing heat, and when it is releasing heat.

A variable speed drive (VSD) controls the speed of the high-torque, direct-drive motor for optimal fan operation.

The growing electricity demands being placed on the country’s century-old grid are resulting in an increased number of unexpected power outages across the U.S.

Whether you’re the owner of an HVAC contracting company or a student at a tech school, take this quiz to find out how much you know about servicing equipment.

Before servicing any refrigeration or air conditioning systems that contain an oil pump, technicians should make sure they understand the difference between net oil pressure and oil pump discharge pressure.

The first time a technician has to tackle a ductless mini-split can be nerve-racking, but by following these 10 tips, the job can be done without all the anxiety.
