On Jan. 12, 2016, Paul McElwee, a CroppMetcalfe HVAC technician, visited a home in Maryland on a no-heat service call. Shortly after entering the home, McElwee identified the problem as a cracked heat exchanger. The cracked heat exchanger was leaking dangerous levels of carbon monoxide (CO) into the home.

Nest Labs Inc. announced today the addition of Control4, Crestron®, Remote Technologies Inc. (RTI), and Universal Remote Control (URC) — along with Dropcam — to the increasing number of products, apps, and services that work with Nest products.

While contractors may not yet feel the effects of these changes, they will in the future, which is why they should familiarize themselves with the new version of Standard 62.2.

Unsafe levels of carbon monoxide, carbon dioxide, and other toxic gases can threaten the health and safety of occupants inside buildings and homes. 

Portable, the Monoxor^® Plus carbon monoxide analyzer delivers quick, accurate CO — 0-2,000 parts per million (ppm) in 1-ppm increments — and temperature measurements to residential and commercial contractors, safety technicians, and weatherization specialists who are performing IAQ and safety checks. 

When dangerous amounts of CO are detected, the CO1224T and CO1224TR CO detectors alert residents by sounding and flashing a temp 4-signal alarm.
