Zoning remains a small but growing segment of the overall HVAC market, representing less than 5 percent of equipment sales.

Customer comfort is the top sales driver in the HVAC industry, or at least it should be.

Zoning technology has experienced success in both residential and commercial applications of hot water and hydronic systems.

How many of standard HVAC sales include add-ons like a humidifier, air cleaner, HRV/ERV, UV lights, or zoning?

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

Contractors have numerous options for offering homeowners solutions in energy management systems.

What is the best approach to providing a holistic smart home experience for consumers?

Contractors and HVAC technicians can create a wealth of opportunities by adding residential HVAC zoning to their list of services.

“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.

For more HVAC contractors to sell zoning systems, they have to understand the benefits, challenges, know how to approach customers to even be able to sell it, and then comes the install.

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.

His jacket was emblazoned with the logo of a manufacturer of high-performing heat pumps, but when I mentioned that we were thinking of getting one, the tech shot down the idea.

Industry experts are telling contractors to stay informed and get involved with the new regulations that are likely to impact everyone this coming year

Hybrid systems offer a pathway that balances environmental concerns with practical considerations, ensuring a more sustainable and feasible transition towards cleaner energy sources.

Customers looking for increased value out of their HVAC systems will find high-end features like connectivity, greater efficiency, and more intuitive controls attractive.

What are the most common mistakes in heat pump installs, and how do you avoid them? Here’s what experts had to say about heat pump installation — a must-watch as electrification continues to gain momentum.

All-electric options have come a long way since their inception, and there’s never been a better time to get on board.

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

The equipment in this month’s troubleshooting problem is an electric furnace that has been in service for at least ten years and has no service history.

Any furnace with induced draft combustion may occasionally exhibit unburned gas odor near the furnace in the off cycle.

HVAC industry representatives are pushing back on a bid by more than two dozen public interest groups for an eventual ban on new fossil-fuel-burning heating appliances.

Two major HVAC industry organizations have weighed in on a DOE proposal that would phase out noncondensing gas furnaces for consumer use beginning in about six years.

If contractors in colder climates focus on educating their customers on what new higher-efficiency furnaces bring to the table, often times the furnaces will sell themselves.

The ACHR NEWS visited Flame Furnace in Warren, Michigan to learn how to do maintenance and basic troubleshooting on a furnace.

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.

Manufacturers will have five years, from the date the rule is published in the Federal Register, to ensure that new gas furnaces comply with the new minimum.

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 winter, HVAC contractors might be dealing with a wetter winter than years past, coupled with more snowfall than maybe most people would like.

Due to a lack of training, time constraints, and numerous other reasons, many HVAC contracting companies are not performing combustion testing, potentially compromising customers’ safety.

The final rule from the U.S. Department of Energy, issued recently, requires newly manufactured indoor residential gas furnaces to be at least 95% efficient starting in December 2028, meaning furnaces made after then will have to be condensing models.

Taking a look at the major concerns around replacing an 80% furnace with a high-efficiency one such as venting requirements, drilling extra holes, and financial costs.

U.S. Senator Ted Cruz is leading the charge to assist HVAC contractors in pushing back on the final rule on gas furnace efficiency standards from the U.S. Department of Energy (DOE).

Using water to transfer heat energy into the home can minimize or even eliminate the issues of dry air and loud operation.

There are plenty of reasons to shut down a potentially dangerous furnace, just make sure the facts back up that decision. 

If contractors don’t have a plan in place to handle red tag furnace second opinions, they can expect some mistakes.

A homeowner in Pickering, Ontario works with an experienced HVAC pro to improve comfort, efficiency, and energy savings with a high-efficiency hydronic forced-air furnace upgrade.

This Episode as well as the next one take a look at remoting infrastructures such as CORBA, .NET Remoting or Webservices. In this first part we will take a look at why remote communication is necessary in the first place, what remoting middleware can do for you as well as which other middleware technologies exist in addition to OO-RPC systems, such as messaging middleware. Finally, we conclude with a brief overview of what the broker pattern can do for us in the context of remoting middleware.

Ruby has been getting more and more attention by the developer community over the last couple of years. Nevertheless Ruby as language and as a plattform is not too widespread. Most developers don't know people who have actually done commercial Ruby projects. Therefore it is sometimes hard to judge if Ruby is just a hype topic or if Ruby can be used for serious projects today. In this episode Alexander speaks with Thomas Quas about a commercial Ruby project Thomas finished a while ago. Thomas shares his insights and practical experiences with Ruby doing a project under strong time pressure. As Thomas has many years experience doing Java projects we also do some high level comparisons between both platforms.

This is a short episode that outlines the upcoming episodes and interviews, as well as reports on some listener feedback.

This is an episode with some more of your feedback. Specifically, the episode also contains a 5 minute section from Geert Bevin where he explains how Continuations are used an implemented in the Rife Framework. This is in response to a discussion about continuations and Rife in Episode 15, Future of Enterprise Java. We also have some feedback from Bill Pugh about flaws in our description about the problems of double-checked locking in Java.

Changeable software has been a goal of several technique in software engineering. Probably the most important is Refactoring, changing the code without changing the behaviour (or at least without breaking the tests). In this episode Eberhard talks with Martin Lippert about this technique. The episode covers a history of refactoring, a definition of code smells and how to actually do refactorings in your everyday work. Also some advanced topics - like the ROI of Refactoring or Refactoring in dynamic languages - are covered.

In this episode, Arno and Michael take a look at Design by Contract, a programming technique formalized by Bertrand Meyer. The idea is that an interface is more than method signatures - it is also about specifying the expected behavior that implementations must provide. While some languages include direct support for this style of programming, it is a useful mindset when desiging interfaces even without such language features.
