is aircon gas toxic

Ah, aircon gas – the silent, invisible companion of every Aussie summer. Most modern air conditioners use refrigerants like R-410A, which aren’t exactly toxic but are far from a health tonic. If leaked in a confined space, these gases can displace oxygen and cause dizziness or worse, but they’re not poisons you can sniff for fun. Older systems might have used refrigerants like R-22, which can be harmful and are phased out due to ozone depletion. So, while not outright toxic, treat your aircon gas like a dodgy ex – best kept sealed and handled by a professional.
