An A/C recharge puts the refrigerant back to the weight your vehicle specifies, after the leak that let it out has been found. We do the whole job at your location. Call 704-842-9774.
Recovery machine, vacuum pump, scales and gauges travel with us, so the recharge is measured rather than guessed.
Charged By Weight
We charge to the exact gram figure on your underhood label. Overcharging cools worse than a correct charge and strains the compressor.
Leak Check Included
Refrigerant is not consumed, so a low system lost it somewhere. We look for that before we put gas in.
We read the pressures, check for leaks, recover whatever is left in the system, pull it into vacuum, then charge to the labelled weight and measure the vent temperature.

The gauges tell us whether a recharge is even the right answer. A system with normal pressure and warm air has a different fault, and adding refrigerant to it makes things worse.
2
We show you the pressures and the leak test result. If the system needs a repair first, you get that price before we go any further.

Recover, vacuum to draw out moisture, hold the vacuum to prove the circuit is tight, charge to weight, then check high and low side pressures and vent temperature before we leave.
All of it is equipment work rather than lift work, so a driveway or a parking space is as good as a shop bay.
The can of refrigerant from the parts store is where a lot of Charlotte A/C problems start. Those kits have no scale and no vacuum, so the system ends up guessed at rather than measured, and an overcharged system cools worse than a correct one while putting extra load on the compressor. That matters more here than in a mild climate: the city logged 72 days at or above 90 degrees this past summer against a normal 44, and in traffic there is barely any air moving through the condenser to shed the heat. The other thing a can cannot do is find the leak, and since refrigerant is not used up, every low system has one. We trace it, fix it, then charge to the weight on your underhood label.
A recharge is measured work: the correct weight of refrigerant for that vehicle, not a can from a shelf. It belongs under Auto Repair Shop Charlotte.
A system that empties again within a season has a failed component rather than a slow leak, and that gets said plainly. Replacing compressors, condensers and lines is covered by Auto A/C Replacement Charlotte.
The recharge calls that come in most often around Charlotte, and what they usually turn out to be.
A system topped up with a store can that went warm again in a month. The leak was never found, and often the charge was well over spec. We recover what is in there, find the leak and start again properly.
Cooling that fades a little more every summer. A slow seep at a hose fitting or the compressor shaft seal. Annual top-ups treat the symptom; tracing it with dye or a detector ends it.
No cooling at all after the system sat unused over winter. Sometimes a lost charge, sometimes a seized clutch or an electrical fault stopping the compressor engaging. The gauges separate the two in a couple of minutes.
Common recharge questions: what it includes, how long it takes, and why the leak has to be dealt with first.
1
Cars, SUVs, light trucks and vans, on both R-134a and R-1234yf systems. Heavier trucks go through our truck repair service.
2
Call 704-842-9774 with the year, make and model and where the vehicle is parked. We confirm the refrigerant type and charge weight from that.
3
Not a problem. It is printed on a label under the hood, and the service port fittings differ between the two types, so there is no guesswork involved.
4
Around 30 to 45 minutes when the system holds vacuum and no repair is needed. Leak tracing or a component repair adds to that, and we tell you before starting.
