Complete 1 system a/c repair and preventative maintenance check. No cool mini-split system. Found system low on r410a. Performed leak search and found a leak at suction line connection at the outdoor unit. Removed charge, cut the connection and flared out a pipe for a new connection. Reconnected line, pressure tested with nitrogen and pulled vacuum. Weighed 2 pounds and 12 ounces of r410a into the system. The system is cooling at this time. Thank you so much for your business today!
