An A/C system loses some refrigerant every year, even without a fault. If it blows weak or warm, it usually just needs a recharge.
We connect the station, recover what's left, vacuum-test the system for leaks and refill the exact amount of refrigerant with oil.
If the system doesn't hold, we find the leak and tell you what to do about it. The best time for a recharge is spring, before the heat.
