Panasonic Corp. of North America is honing in on its focus to make it easier for both residential and commercial building owners to control the temperature and comfort level within the space. The company hit its targets with the introduction of two new products — the ECONAVI air conditioner and the Variable Refrigerant Flow (VRF) Smart Connectivity Controller.

It is 2018, and this is not your father’s rooftop equipment. The old, reliable system taking up space on the roof has become so much more.

Corporate America is making pledges to take action against climate change, which is opening up opportunities for HVAC contractors.

Smart products enable service providers to take a more proactive approach to addressing HVAC system and equipment issues, said Susie Gornick.

Honeywell announced the launch of Honeywell Forge Energy Optimization, a cloud-based, closed-loop, machine learning solution.

RetroFIT+ is the next iteration of the Belimo retrofit program, which offers online resources, including a product-selection tool, as well as personal support to provide quick and easy access to HVAC replacement solutions for actuators, valves, and sensors.

After six meetings, the working group reached consensus and provided recommendations for energy conservation standards, test procedures, and metrics.

Since they don’t have to stay in one place, portable cooling units have been known to show up in some pretty unique places. Here’s a closer look at how portable units are serving in some outside-the-box applications.

A series of geothermal heat pumps from Enertech Global swept the HVAC Light Commercial Equipment category of the 2015 Dealer Design Awards, starting with the gold award winner, the TVS/TVT TETCO Commercial Series Geothermal Heat Pump.

Nortek Global HVAC has introduced a new three-phase electric/electric packaged cooling solution. The company said the Model P8SE delivers 14 SEER cooling in capacity ranges from 3 to 5 tons in even tonnages, making it an energy-efficient choice for strip malls, restaurants, and retail stores.

Every year, The NEWS introduces the latest cooling equipment available for the upcoming summer season in order to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands. The coverage features specific information about each individual product as submitted by the manufacturers.

The manufacturers provided all of the data included in the product grid as well as the photo feature. Therefore, any questions should be directed to them via the contact information provided in the photo feature section.

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.

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.

Summer cooling season is in full gear, which means that both technicians and their tools are being kept extremely busy.

AI technology can help HVAC contractors monitor each sales and repair call.

Is reducing a facility's energy consumption by over 130,000 kWh annually through HVAC optimization possible?

Today’s commercial structures are full of sophisticated controls that have been changing building automation systems exponentially.

Daikin Applied’s recently introduced SiteLine Building Controls gives building owners and operators the tools and insights needed to optimize performance, improve IAQ, and trim energy use and carbon emissions.

Siemens is working to expand their offerings to fit any building size, with any amount of complexity.

While a controls upgrade may be costly, the reality is, the longer you wait, the more expensive a replacement can be.

The ESP-400 by Jackson Systems LLC has earned gold in the Residential Controls category of The NEWS’ 2017 Dealer Design Awards.

Over a year of research and design went into the 2018 Dealer Design Awards gold-winning product in the Residential Controls category. After listening to feedback from both contractors and consumers for a more basic, easy-to-use, and cost-effective thermostat, Nest created the Nest Thermostat E.

The project team and property management realized they needed to maximize open space for use by hotel guests. They chose LG’s Multi V™ 5 and Multi V™ S VRF systems, noted for energy efficiency and flexibility in design and installation options.

For years, ZoneFirst President Dick Foster has used the light-switches-in-the-home comparison while promoting the benefits of zoning. At their AHR Expo booth, they introduced a product that brought new meaning to that comparison.

With cost reduction, sustainability enablement, increased comfort and performance benefits, VRF systems allow commercial buildings to gain a competitive advantage by reducing their carbon footprint and providing custom comfort to occupants.

Only 4% of homeowners know modern heat pumps can heat down to -4°F. That’s a huge opportunity for HVAC contractors to step in and be the experts.

This e-book includes a summary of sustainable HVAC developments, in particular of heat pumps and refrigerant changes to address climate change.

In this showcase, The ACHR NEWS introduces the latest cooling equipment available for the upcoming summer season in order to help contractors distinguish between brands.

Contractors must be careful when sizing heat pumps for colder climates in order to avoid mold problems and homeowner discomfort.

To meet the ambitious environmental goals being proposed at all levels of government, residential air-to-water heat pumps are emerging as a transformative solution to lower carbon emissions, enhance energy efficiency, and reduce utility bills.

“(I’m Your) Heat Pump” is a soft, funky, R&B love song told from the perspective of a heat pump that depicts just what a heat pump can provide to its users.

This new private-public partnership wants to quadruple heat pump installation in California over the next 6 years.

The DOE's new Rooftop Accelerator program encourages manufacturers to develop efficient commercial rooftop heat pumps for cold climates, which could reduce GHG emissions and energy costs by up to 50%.

Cold climate heat pumps were on full display on the AHR show floor and manufacturers were eager to share their progress reports in the Department of Energy’s CCHP Challenge.

Throughout March, voters will help the staff at Peterman Brothers select four charity partner organizations for 2023.

Residential gas furnaces must all have a minimum AFUE of 95% beginning in five years. Some in the HVAC industry say the new Department of Energy rule will ultimately hurt homeowners.

This week, Arno and Markus take a look at error handling at the architectural level. They discuss the different kinds of errors, the groups of people who need to know about them and proven high-level approaches. Later episodes will investigate more technical aspects of error handling, such as idioms for using exceptions or a discussion of checked vs. unchecked exceptions.
