Why Is My Car AC Not Blowing Cold?

North Potomac, MDTony Automotive

If your car's AC is blowing warm or weak air, the most common cause is low refrigerant from a leak, followed by a failing compressor. A recharge might get you cold air for a little while, but if there is a leak, that cold air will not last. For lasting AC repair around North Potomac, call Tony Automotive at 301-401-6669 and we will find the leak instead of just masking it.

Refrigerant does not get used up like fuel. If your system is low, it escaped through a leak somewhere — a hose, a seal, a fitting, or a component. That is why simply recharging it is a temporary fix. We test the whole system, locate the leak, and repair it so your air stays cold through the summer.

There is more to comfort than the AC, too. The same system handles your heating, so it is worth thinking about year-round. Our AC repair and heating service covers compressors, blower motors, heater cores, and the diagnostics to figure out which part is actually failing, whether you are fighting Quince Orchard summer heat or a cold January morning.

Do not sweat through a Maryland summer with weak air. Call 301-401-6669 and we will get your AC diagnosed and blowing cold again, the right way.

Why is my AC blowing warm?
