Super-Heat is defined as any heat added to a substance beyond its saturation (boiling) temperature. Simple right? Actually, this is usually where people begin to get confused …. after all, doesn’t boiling indicate hot and aren’t we talking about air conditioning?

An HVAC brand is more than just a logo, slogan, and catchphrase—a “brand” is what your customers feel or think when they see or hear those things. In order to make a mental connection with your customers, you’ll need to develop a personal, emotional, and social brand identity. Once you establish what your HVAC brand is all about, you can start standing out against your competition, build long-term relationships with customers, and drive business growth.

Guess what the top HVAC/R industry trends are for 2019? If you answered energy efficiency and going green, you’re on the right track.
These were the top most important trends attendees of the recent ASHRAE- and AHRI-sponsored AHR Expo predicted for this year. They’re also the focus of two regulations that could impact the industry in 2019.
Read on to learn all about them and how they could shape your work this year.
Welcome to what was intended to be my second article on refrigeration circuit practices and the importance of pulling a good vacuum on a system during installation or repair. This was going to be the time where I discussed POE oil being
Welcome to the first of a two-part series covering the subject of key refrigeration circuit practices. In this post, I will be discussing the importance of properly using nitrogen when brazing refrigerant lines. The process is called “sweeping” and this is not a new process. What has changed over the years is that POE oil has become the predominate refrigerant oil used throughout the world. One characteristic of POE oil is that it’s an excellent detergent and will literally clean the inside of tubing within the refrigerant circuit. This will become problematic when short cuts are taken during installation.
The topic of refrigerant has been an ongoing saga since we first announced the phase-out of HCFC R-22 in 2010. There have been numerous rumors circulating throughout the years about what would happen to refrigerant and when it would happen. We have lived through a roller coaster of prices with not only R-22, but with R-410A as well. However, it is important to keep in mind that the value of anything in the world is only what you can find someone willing to pay for it. So, here we are in 2019, and I am not sure we have any better grasp on where we are headed than we did nearly ten years ago.
In the depth of winter, the weather outside is frightful and the heat pump is “chugging” away to keep the inside delightful. Without our trusty defrost cycle in these conditions our heat pump would quickly begin to look like Frosty the Snowman…minus the jolly part. There’s nothing jolly about a broken heat pump.
The defrost cycle is what allows for our heat pumps to continue efficient heating operation in cold weather. However, the actual operation of the defrost cycle is often not understood as well as desired. This leads to improper settings as well as misdiagnosis. Let’s dig into the basic concept of a heat pump operating in heat and the defrost cycle that protects it.
