New Handheld Invention Improves Diagnostics and Troubleshooting on Gas Furnaces

July 20, 2010

CINCINNATI, July 20 /PRNewswire/ — A new tool named the “Draft Simulator” tests Pressure Switches by ensuring they open and close at their manufactured ratings. The invention is also used in finding a switch with a bad or weak diaphragm and verifying switch consistency.

The handheld tool was invented by Richard McFarland, a service technician in the HVAC industry since 1975. It weighs in at 13.7 ounces with its battery inside, and is measured at 6.5 inches in length, 3 and 5/8 inches width, and 1 and 3/8 inches thickness. Its lightweight design and handheld size makes it ideal for portability and ease of use in the field.

The Draft Simulator works by connecting to a manometer and the pressure switch using small rubber tubing. After the leads are connected to the pressure switch, a knob at the top can be turned to adjust suction to the pressure switch which, in turn, simulates the behavior of the Draft Inducer. Without the furnace running, technicians are capable of verifying the operation of any pressure switch.

An unnoticed faulty switch may result in undesired service warranty visits, lost potential income, and additional time spent diagnosing intermittent failures. “You spend hours and even replace good parts, until finally, you catch it in the act and it was the pressure switch all along!” said Richard McFarland, Inventor.

The Draft Simulator has caught the attention of instructors and contractors in the HVAC industry.

“Wow, this takes testing pressure switches to a whole new level! I can’t believe how easy it is to use. It makes other methods of testing seem so dated. It is amazing how you can test a pressure switch with such accuracy. If I was a tech in the field I would only carry a good adjustable pressure switch. Set it and forget it; this thing is slick!” said Adam Elza, HVAC Instructor at Great Oaks Institute of Technology and Career Development, Live Oaks Campus.

“You can make more money testing pressure switches,” said William Potts – President of Potts Heating & Air Conditioning. “It has reduced call backs, and improved our cost of doing business; it even allowed us to earn customers because other companies couldn’t figure out what was going on.”

The Draft Simulator is under US Patent NO 7,441,439 B2. It is currently for sale at http://www.pressureswitchtester.com. For more information, please visit our website.
