Rain drops in my central air/furnace unit?

Photo credit: @GeorgeBrazilPhx

Tresq13 asks: When it is raining I can hear pinging noise that sounds like rain drops in my central air/furnace unit in my basement. There is no rain on the ground near the unit and it appears dry within. At first I thought it might just be condesation drip sounds but it seems too coincidental that it was during a rain shower.

Any idea what this is?

Answer: With a gas furnace water could be dripping down the flue pipe or just pinging on it. Sound travels very well through steel. (Is it a problem?) Long term yes… it could rust several components and cause them to fail earlier than normal – Tranic

PRO-Fit™, the Next Generation of Reliable Refrigeration Pipe Flaring

PRO-Fit™ Precision Flaring Kit produces tubing flares in just seconds without splits, blemishes and burrs that cause leaks associated with slow traditional flaring tools/blocks.

RectorSeal®, Houston, a leading manufacturer of quality HVAC/R tools and accessories, introduces the PRO-Fit Precision Flaring Kit, the next generation pipe flaring tool for copper and aluminum tubing used in air conditioning and refrigeration work. PRO-Fit’s unique pipe flaring tool design/method is the easiest, quickest and most reliable method, because it helps prevent potential sidewall splits and leaks associated with slow traditional flaring tools when forming 45°, field-applied refrigeration tubing flare connections.

The kit consists of five bell-shaped, color-coded, size-inscribed flaring bits designed for 1/4, 3/8, 1/2, 5/8 and 3/4-inch (6, 7.5, 12, 16, 19-mm) tubing. The flaring process requires just seconds to complete using a (minimum) 12v drill or impact driver. The spinning bit forms the tube opening into a flare, without splits, burrs, blemishes or uneven edges that typically cause flare fitting connection leaks. The bits are also the most efficient option for flaring short stubs or existing tubing in cramped spaces with limited accessibility for traditional flaring tools/blocks.

The kit’s 7.5 x 11 x 2-inch (19 x 28 x 5-cm) clear durable plastic carrying case includes an interior foam organizer with cutouts sized to fit each respective bit. A four-color 7.5 x 11-inch instruction sheet mounted under the foam is readable through the bottom of the plastic case bottom without removing.

Other features of the PRO-Fit Precision Flaring Kit include:

  • Laboratory endurance testing proves bits last twice as long as competitors;
  • No-slip, 1/4-inch-diameter hex-shaft for the industry standard 1/4-inch hex chuck;
  • Hardened tool steel bits with a proprietary machine shop-grade non-corrosion coating;
  • Available to HVAC/R wholesale distributors in four-unit cases;
  • and replacement bits are available through distributors.

Product available early August 2017.

The kit is the first offering from RectorSeal’s newly-created PRO-Fit brand. Going forward, Rectorseal will continue to introduce more tools and consumables for the HVAC/R trade.
