RIDGID will select six winners for a VIP experience at its global headquarters.

In the past few years, the thermostat has become a cutting edge electronic. This creates new opportunities for HVAC contractors.

The NEWS was very busy at the AHR Expo in New York City, visiting as many booths as possible in search of new products. Below is a comprehensive list of all the HVAC commercial equipment we found on the show floor.

The HVACR industry was initially surprised by a date-of-install requirement, mandating installation of certain equipment by January 1, 2025, but EPA extended sell-through period to January 1, 2026.

The EPA initially faced backlash from the industry regarding the sell-through mandate for certain HVAC systems. The Agency revised the provision by allowing one additional year, until January 1, 2026.

In recent years, the cost of HVAC equipment has increased significantly, and regulatory changes, such as the phase-down of R-410A, will make the new A2L units even more expensive.

In early July, the Biden administration proposed a rule that addresses excessive heat in the workplace, as tens of millions of them were under heat advisories — the nation’s No. 1 weather-related cause of death.

Sales of VRF systems continue to rise unabated, leading many to predict their shipments will increase by double digits annually for the foreseeable future.

The NEWS’ Extra Edition page is home to hundreds of online-exclusive service and maintenance, technical, and business management articles. Here are some of the best.

Developments in zoning capabilites have brought mini splits into the multiroom realm. And it goes without mention that the march of engineering progress has taken ductless systems on the road, into parts of the country where no mini split has ever gone before.

Most of the rest of the world has relied on ductless mini-split systems for their heating and cooling needs for decades, but that has not been the case in the U.S. That may be changing with the advent of ducted mini-split systems.

The EEV is often used in modern refrigeration systems, but troubleshooting its common failures may be complicated.

Manufacturers are starting to introduce their A2L systems in the U.S., so contractors and technicians must learn how to service and install this new equipment.

In today's economy, cost-conscious end users want to extend their HVAC equipment lifespan as long as possible. Regular maintenance on condensing units can help maximize their longevity and performance.

Ensuring a vacuum pump system is evacuated and free of air, nitrogen, moisture, and other contaminants is a crucial step to keep the system running optimally.   

The Inflation Reduction Act’s major incentive for the installation of a qualified geothermal system is a 30% federal clean energy credit, which can be used at filing time to offset taxes owed or add to any refund.

When changing the refrigerant within your pumping application, it is worth discussing the application with a process specialist.

Often considered to be an affordable, reliable heating and/or cooling system for a variety of commercial buildings, the standard rooftop unit used to come with a basic thermostat that is limited to turning the system on or off. The advent of new controls has changed all of that by allowing rooftops to monitor operation, analyze conditions, and make real-time decisions that can optimize performance.

Emerson continues to evolve its equipment lines in an effort to introduce its technologies to a broader customer base.

Aaon’s focus on serviceability and performance helped the WH Series earn gold in The NEWS’ 2017 Dealer Design Awards HVAC Light Commercial Equipment category.

These compact datalogging instruments offer users a durable design with flexible programming configurations and the convenience of datalogging readings in Excel format directly onto an SD card.

SD900 and SD910 three-channel DC current and DC voltage dataloggers are optimized for extended monitoring of milliamp (SD900) and millivolt (SD910) signals throughout a commercial, industrial, or residential facility.

The Extech TH30, RHT30, and RHT35 compact dataloggers are designed to provide HVACR professionals with easy access to real-time temperature, humidity, and barometric pressure readings as well as insights compiled from extended readings preformatted in Excel or PDF report formats. Users can set and forget the dataloggers with a customizable recording rate from once every 30 seconds to once every two hours, and it holds a capacity of up to 48,000 combined total readings with date and time stamps.

Just like bees return to the hive every day for sunset, Yellow Jacket has habitually returned to the AHR Expo every January for the past 45 years.

This handheld device displays CO, CO₂, air temperature, rh, dew point, and wet bulb temperature measurements.

Designed for HVAC and refrigeration professionals to view electrical and temperature readings, this product logs data remotely using the ExView® W-Series app on smartphones and tablets via Bluetooth.

NASRC has launched a workforce development program that focuses on recruitment, training, and retention, in order to combat the critical shortage of refrigeration technicians. 

With stronger global temperature fluctuations and demand for HVAC systems growing, heat exchangers are rapidly becoming essential to an ever-expanding market.

The upcoming expo will preview the future of the HVACR industry, with exhibitors from around the globe gathering to showcase new and upgraded products, technologies, and innovations.

Cochrane Supply & Engineering has been distributing Honeywell products since Cochrane was founded. Co-founder Don Cochrane Sr. got his start with Honeywell.

Products are emerging that help simplify homeownership.

“The acquisition of California Economizer and its Zonex Systems brings together the two oldest manufacturers of zoning dampers and zone-control systems,” said Dick Foster, the president of Zonefirst and its parent company, Trolex Corp.

As heat pump technology advances and begins its march into colder climates, industry experts are expecting rooftop units to continue to gain popularity in both new construction and retrofits.

This is the first of two episodes where Arno and Alex discuss eXtreme Programming in se-radio's development process track. eXtreme Programming (XP) revolutionized the way of thinking about software development methodologies and helped to make the agile movement popular. In this episode they discuss the very basics of XP, its value system, principles and the basic practices used in an XP project. The second episode will continue the introduction adding the missing practices and how to introduce XP into projects.
