IF your AC is down, use this to power back up!
We have AC on the hottest days of the year!! Thanks to this product sealing where ever the leak was, our system is up an running just fine. IF our system goes down, we will then go looking for the leak, with again thanks to this product's dye.

Easy to install if you have the gauges.
My HVAC guy said I had a leak in evaporator coil. He went ahead and put some refrigerant in the mean time. I went ahead and ordered this sealant and installed it myself since I have the gauges. We will see if it holds. I expect it to seal. This product has very good reviews. I also like the idea as a preventive measure. I manage properties, and in this area no cooling becomes a crisis.
