low on refrigerant

do not reccomend doing it yourself no sealer, contaminates the system. fix the leak. diag is 39.95 average repair is between 200-350 with evac and charge Roy

Get a kit with a gauge - it'll tell you how much refrigerant you need. They have good instructions on the bottle. I put in leak sealer and then later I read that after time the leak sealer breaks off inside the HVAC system and fouls it up. If I could do it over again I wouldn't have got the leak sealer. It should cost less than $40. If you take it to a shop - who knows, $250 - $600? It takes maybe 15 minutes in the parking lot of the store you buy the can at. DIY.
