ST. LOUIS - Emerson Climate Technologies, a business of Emerson, has announced the availability of a toll-free technical service number in support of Comfort Alert Diagnosticsâ„¢. The technical service number (888-923-2323) allows contractors to contact specialized technicians when they have questions while working with units that contain Comfort Alert Diagnostics. The number helps to ensure that contractors, especially those who are unfamiliar with or have limited exposure to the product, are able to adequately take advantage of the product's diagnostic benefits when servicing units.

Introduced in 2003 as part of Emerson's UltraTechâ„¢ Home Series, Comfort Alert Diagnostics is designed for troubleshooting heat pumps and air conditioning systems. Comfort Alert helps guide service technicians more quickly and accurately to the root cause of a problem.

"With many manufacturers now featuring Comfort Alert Diagnostics in their units, the technical service number provides contractors with the ability to speak directly with specialized technicians about taking advantage of Comfort Alert Diagnostics to troubleshoot system problems," said John Schneider, director residential marketing for Copeland's air conditioning division.

According to the company, Comfort Alert Diagnostics improves diagnostic troubleshooting accuracy and speed of service by using the Copeland Scrollâ„¢ compressor as a sensor for system faults and communicates fault codes via flashing LEDs in the outdoor unit. With built-in communication, Comfort Alert also improves system reliability by communicating fault codes to a White-Rodgers thermostat which protects the compressor when severe, damaging faults are detected.

This year, Comfort Alert is expected to be installed in approximately 500,000 residential cooling systems including systems from Aaon, Arcoaire, Amana, Armstrong, Comfortmaker, Frigidaire, Heil, ICP, Keeprite, Lennox, Maytag, Tappan, Tempstar, Rheem, Ruud, Westinghouse, and York.
