One can will normally repair a leak in systems up from 1.5 to 5 ton. If you have a smaller unit, please contact us.
If the a/c system that will not hold a vacuum, you need to use the Enviro-Safe Prodry XL4.
The reason for the vacuum or the use of Enviro-Safe Prodry XL4 is that it will eliminate moisture in the system. Moisture mixing with oils and refrigerant can cause you system to make sulfuric acid which will corrode and eat your system!
**ProDry, Removes Moisture from System
Should be used in all systems to prevent acid-corrosion.

Use before ProSeal XL4 to protect sealants from reacting in system.

Protects against leaks formed by corrosion.
Enviro-Safe ProDry XL4 contains a dehydrating agent that converts system moisture into oil. We recommend the use of ProDry XL4 before the use of Enviro-Safe ProSeal XL4 to ensure all moisture has been removed from the air conditioning system.
Should be used on any home A/C system that has leaked below 15 psi (running or not running) or if the system has ever leaked below 15 psi in the past.  If you do not wish to use Pro Dry XL4, the system must be vacuumed prior to installing ProSeal XL4.
When put into an A/C system that has moisture or air, Pro Dry XL4 mixes with the moisture and air in system forming a synthetic oil which then mixes with the oil in the system.
