It will detect gasoline fumes but is not a carbon monoxide detector.

Although I have never tried it on refrigerant. The unit is made to detect combustible gasses. As is stated in the specs.

Flat batteries

A little disappointed to find that the batteries that came with the unit were flat and wouldn’t power the unit. Once batteries were changed everything was fine.
