Ducts play a crucial role but are often overlooked.

The ductless market has grown significantly in the U.S. in the last 20 years. What was once a fringe product has become a prominent subset of the HVAC world.

During my time in this industry, I think we’ve done a really good job of adding more women across different fields. Women don’t always think about HVACR, but it’s an industry that needs good leaders just like any other.

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.

Refrigerant regulations are another reason why change is coming, as HCFCs will be phased out by 2020, and given their high global warming potential (GWP), HFCs will likely be phased down in the near future as well. At some point, supermarkets will need to start considering low GWP alternatives such as HFO blends, as well as so-called “future-proof” refrigerants such as ammonia, CO2, or propane.

These Emerson half-day CO₂ transcritical booster supermarket refrigeration courses will take place March 28, 29, and 30 at the Energy Education Center in Irwindale, California.

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

Michael Daly, chief technology officer, ECM Technologies, offers insights into the HVAC commercial market.

While “smart” tools and tablets are becoming more and more common in an HVAC tech’s toolbox, there are still plenty of things an app just can’t do.

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

With a little ingenuity, HVAC contractors could come out on top in the smart homes market for years to come.

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

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.

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

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

Not only has VRF technology been widely accepted by contractors and end users alike, virtually every major U.S. manufacturer is now offering these systems, as well.

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.

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

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

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

In supermarkets, where HVAC and refrigeration equipment use 50 to 60 percent of all electricity consumed, new technologies and advanced control strategies have been developed to help boost energy efficiency as well as reduce emissions.

The benefits of portables, including speedy implementation, reduced downtime, and cost-effectiveness, are continuing to gain recognition from end users. And, as end users experience these benefits and the resulting uptime, industry experts expect the portable market to continue to heat up.

Each year, The NEWS spotlights the industry’s latest commercial heating products. The manufacturers provided us with a brief description of features included with each product.

This product is a leave-behind HVAC analytic device that technicians can install on each unit, regardless of the brand they service.

With the demand for new homes skyrocketing, more HVAC businesses are opening to meet demand, according to two new reports.

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

There is a new term making its way into the commercial controls arena: digital twin.

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

When it comes to comfort, not much beats zoning. In fact, many industry experts tout that once homeowners have experienced the comfort zoning has to offer, they will never own another house without it.

For residential HVAC contractors, smart homes are a fast-growing market that offers opportunity for profit.

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.

Gernot Starke talks about arc42: an open-source set of templates he developed to document software architecture based on his practical experience with real projects. Also Gernot and host Eberhard then discuss how documenting architecture fits into agile processes and how to find the right amount of documentation for a system. They walk through the different parts of the arc42 templates covering requirements and the context of the system and the solution structure, including building blocks, runtime, and deployment. They discuss tooling, versioning, testing documentation, and how to keep documentation up to date.

Mike Barker talks with Sven Johann about the architecture of the LMAX system. LMAX is a low-latency, high-throughput trading platform. Their discussion begins with what LMAX does; the origins of LMAX; and extreme performance requirements faced by LMAX. They then delve into systems that LMAX communicates with; LMAX users; the two main components of the system (broker and exchange); Mechanical Sympathy as an architectural driver; message flow using the Disruptor library; and lock-free algorithms. Mike and Sven wrap up by discussing how a well modeled domain model can improve the performance of any system; automated (performance) tests; continuous delivery; and measuring response times.

Nate Black talks with Jonathan Stark about platforms for mobile development, making decisions about how to develop mobile apps, how to deploy mobile apps, native apps vs. progressive web apps, React Native, and the future of mobile applications.

Shannon Selbert, co-founder of Soren and developer of Oban, and Parker Selbert, creator of the Oban background job framework, chief architect at dscout, and co-founder of Soren, speak with SE Radio host Gavin Henry about robust job processing in Elixir. They explore the reliability, consistency, and observability in relation to job processing, to understand how Oban, Elixir, and PostgreSQL deliver them.

The Selberts describe why Oban was created, its history, which parts of the Elixir ecosystem they use, and why this would not be possible without PostgreSQL and Elixir. They discuss the lessons learned in the 5 years since the first release, as well as use cases, job throughput, the hardest problem to solve so far, workers, queues, CRON, distributed architectures, retry algorithms, just-once methodologies, the reliability the beam brings, consistency across nodes, how PostgreSQL is vital, telemetry data, best use cases for Oban, and the most common issues that new users face.
