  1. What was that? HVAC simply means “heating, ventilation and air conditioning”. This in no way refers to your review as a type of refrigerant. “Freon” is like saying “Kleenex” when referring to facial tissue. It has no place in the specificity of your review. Stick to refrigerant types “CFC, HCFC, HFC, and HFO”. Your comparison chart shows leak levels in grams and ounces. Surely you could make the conversion for your readers. The prices listed, really? $23 for a leak detector? It probably would serve far better as a paperweight. There were a lot of brands and models not represented in this review that deserved to be considered. I’ll have to rate your review with a “D”. Keep trying and have a covid free day.
