Right tools make difference
By Mark Parliamnet If you are not installing air conditioning units, you're maintaining these machines, which means ensuring that you have the right tools for the tasks you'll be performing for your customers. Thankfully, tool choices are plentiful for our sector, but there are a number of ”must-have” tools that I turn to, since they are designed for ease of use, comfort and accuracy – and ultimately make the task of installing and maintaining this mechanical equipment much easier. And please note, while you'll see a number of my tools in these pages, I am not beholden to any particular brand of product on the tools front, but quality is important, so I tend to stick with some of the better-known brands out there when it comes to equipment that I need to be in calibration with good precision and accuracy. Check the flow Before beginning any maintenance on the air conditioning system, it is important to gain a proper understanding of the total system performance. To properly evaluate the system, the first test to run should be for proper airflow. Without knowing the proper airflow, we cannot be sure that subsequent readings are accurate, no matter the brand or make of tool we use. After all, garbage in (incorrect readings) equals garbage out (incorrect troubleshooting). By using a manometer and static tips after the filter and before the air conditioning coil, you can see the external static pressure that the air mover (furnace or air handler) is being subjected to on the duct system. By consulting the manufacturer's blower performance charts, you will be able to see the exact CFM that is being pushed across the coil. Once you ensure that the system is seeing the proper airflow, you can then move on to a more in-depth diagnosis of the system. How much heat? The next step is to [...]

RectorSeal now introduces Acid-Away PRO, the new quick-and-easy, all-in-one injector for eliminating acid in residential and commercial refrigeration and air conditioning systems. The Acid-Away PRO injector includes a 1.5 ounce dose of the same trusted Acid-Away formula that service technicians have used for more than two decades to eliminate and prevent refrigeration system acid formation. The six-inch-long Acid-Away PRO injector consists of a 1.5 ounce copper reservoir; a high-side 1/4-inch standard brass connection fitting and a low-side 1/4-inch low-loss Schrader valve brass connection fitting designed to protect the service technician's hands from frostbite and the environment from escaped refrigerant. The recyclable injector simplifies and expedites usage versus the original Acid-Away bottle/funnel method. Unlike the original Acid-Away, which was offered in both mineral oil and polyolester versions, Acid-Away PRO has been reformulated for all refrigeration oils. Compared to most competing products, which are defined as scavengers that attach to acid molecules for entrapment in the system's filter drier, Acid-Away PRO chemically changes acid into a neutral, non-corrosive substance that doesn't attack metals or cause future compressor motor burnouts. Unlike scavengers, Acid-Away doesn't deplete filter/drier capacity, which potentially leads to premature filter/drier replacement callbacks. While Acid-Away Pro is designed for compressor burnout system cleanup, it's also an excellent preventive maintenance treatment for systems with a history of acid buildup. Two other RectorSeal products complement Acid-Away PRO: Acid Detector acid test kit and the Turbo-Kleen Starter Kit for cleaning burnout residual from system components. Other features of the Acid-Away PRO include: OEM approval by Trane, Bristol and several other equipment brands Doesn't require replacing filter/drier beyond periodic replacement schedules Reformulation for all refrigeration oils results in only one inventory SKU Prefilled applicator minimizes introducing moisture and air into the system Available to HVAC/R wholesale distributors in countertop cases of 12 units, each which have a peg hole for optional displaying on wall [...]
