The transition to A2Ls will likely serve as an interim solution. Europe has already embraced propane in certain heat pump systems, and the U.S. may follow suit, albeit with a different low-GWP refrigerant.

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.

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

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.

Different areas have particular needs and also embrace new technology at different speeds.

Honing in on the high-end heating market, there have been several changes over the years, but four primary trends stand out among the rest: connectivity, efficiency, aesthetics and health, and upgraded technology.

Once only found in mild climates, the technology now stretches across the U.S., thanks to advances in inverter technology and zone controls. On the other hand, the level of sophistication in these systems sometimes makes them difficult to troubleshoot when something goes wrong.

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.

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.

Across seven product categories, LG’s HVAC solutions again pass AHRI's comprehensive performance certification program.

Troubleshooting refrigeration systems can be complex and frustrating, so put aside any assumptions and inspect the system thoroughly before making any diagnosis.

Over time, dirt, dust, pet dander, debris, and more accumulate in air ducts. And since the HVAC system works basically as a whole-home vacuum, all of that is recirculated through homes when the HVAC system runs, unless the ducts are cleaned out.

The medical profession and the HVAC industry have a lot of parallels when it comes to learning how to work together as a team.

The proposed new approach to chilled water HVAC systems promises to provide significant capital cost savings, energy cost savings, and a path to eliminate CO₂ emissions.

Trained to identify the varying types of asbestos used in old buildings, Matt Mountain of Mountain Duct Cleaning knows what he’s looking for.

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.

In the latest episode of The NEWSMakers podcast, Kyle Gargaro, editorial director for The ACHR NEWS, talks to WaterFurnace CEO John Thomas.

Heat pumps for both space and water heating will be required in most new homes in the state of Washington beginning next July.

Though geothermal systems can cost several times more than traditional HVAC units, the energy savings may be substantial.

Catch up on the latest headlines in our NEWSRoom video series.

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.

As the federal government plans millions in grant funding to boost heat-pump manufacturing in the U.S., a big player in the market as well as a newcomer are thrilled with the opportunity.

As Rochester city leaders set the ambitious goal of reducing greenhouse gas emissions by 50% by 2030 and 100% by 2050, the challenge is now how to follow through.

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.

The bill significantly reduces the cost of a geothermal installation, spurs job creation, and hopes to inspire more contractors to tap into the geothermal market.

Efficient refrigeration and HVAC systems are essential to energy management and operational cost of residential, commercial, or industrial buildings.

We often humidify and dehumidify as part of our work, but let’s take a different look at what happens when we do that.

Selecting a VFD that features remote startup can decrease the number of individuals needed onsite and provide valuable safety benefits.

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.
