Best Car Air Conditioning Repair Near You

Low refrigerant is the usual answer, and that means a leak somewhere. Other causes are a compressor that has stopped engaging, a failed pressure switch, a blend door stuck on the heat side, or a clutch relay. Warm only at idle and cold on the move points at airflow through the condenser, often a cooling fan that is not running. The test tells them which; guessing does not.

For a season, maybe. A recharge puts refrigerant back into a system that already proved it cannot hold any, so unless the shop finds and fixes the leak you will be back next summer. Refrigerant also carries the oil the compressor lives on, and a system run low and dry kills compressors. That is the repair that hurts, so pay for the leak test first.

Yes, and it decides which shop can help you. Older systems use R-134a and newer ones use R-1234yf. They are different chemicals at different pressures with different fittings, and putting one into a system built for the other causes damage. Each type needs its own recovery and charging machine, which not every shop has bought yet. The label under the hood says which you have.

Because the evaporator is cold, wet and dark, which is where mold and bacteria grow. The smell hits hardest on the first start of the day. Start with a new cabin filter, since a soaked one holds the odor. If that does not do it, shops clean the evaporator with a foaming treatment sprayed through the drain or the vents. Running the fan without the compressor for the last few minutes of a drive helps it dry.

The compressor and the evaporator. A compressor that has come apart internally sends metal through the whole system, so the repair usually includes flushing the lines and replacing the dryer and the expansion valve, and a shop that skips that is setting up the next failure. The evaporator is cheap enough as a part and brutal on labor, because the dash comes out. Condensers and hoses sit at the friendly end.
