Contractors who are embracing the technological advancements say ignoring a new neighborhood of home automation products could be a big mistake.

BIM technology has proven to be highly expedient for several HVAC plans, especially in terms of cost efficiency, time optimization, and effective planning.

Cochrane Supply & Engineering offers products for commercial and industrial building comfort, safety, and security as well as world-class technical support, development and training.

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

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

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.

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.

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.

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

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.

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.

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 the first episode on Refactoring we talked about the basic ideas behind refactoring and some base principles why refactoring is a key part of software engineering. Now we move on to more complicated refactorings and discuss three major situations, their problems and possible solutions: advanced refactorings in large projects that can hardly be finished in a few minutes or hours and refactoring in larger teams. Also covered are the refactoring of published APIs and how merciless refactoring could be aligned with backward compatibility of published APIs, and refactorings that affect more than just code like for example database schemas.

Jonathan Schneider, the cofounder of Moderne and the creator of OpenRewrite, talks with SE Radio's Gregory Kapfhammer about automated software maintenance. In addition to exploring the design and implementation of OpenRewrite, Schneider explains how the tool can automatically support software maintenance tasks such as framework migration and security fixes for programs implemented in languages like Java. The episode also explores how OpenRewrite uses the lossless semantic tree to support automated refactoring though the use of recipes.
