Five Signs Your Car AC Needs To Be Serviced

• Your car air conditioning blows only slightly cooler than the outside air.
• Your car's air conditioner blows air that smells like mildew and mold.
• Your A/C only works while driving.
• You have low airflow even at the highest fan setting.
• Water condensing or dripping on your foot while driving.

Don't wait! If your car's A/C is working at reduced efficiency, it's worth a visit to McLearen Shell. Taking care of regular maintenance now can help you avoid more expensive AC repair costs down the road. Sometimes fixing a broken air conditioner is as simple and cost effective as adding new coolant.

Repair Your Car's AC Compressor
Let McLearen Shell Repair Your Car's AC Compressor

The cool air in your car is produced primarily by the compressor. The four main functions that your vehicle's compressor carries out include pressurizing the refrigerant to cool cabin air, monitoring and controlling temperature output, sensing temperature changes inside and outside the vehicle, and moving air to your car's AC condenser.

Repair Your Car's AC Condenser

Your vehicle's A/C condenser is usually located in the front of the radiator. When your AC compressor is pressurizing the refrigerant flows to the condenser to reduce the temperature and pressure. The condenser is a vital component in keeping your car's cabin temperature cool. It moves the cooled liquid refrigerant to the receiver/dryer or accumulator.

Freon Recharging Questions and Answers

Q: How often should Freon be changed?

A: Never, at least not in the way you think of your oil being changed. Your car's AC system is a sealed unit. No new freon needs to be added unless there's a refrigerant leak. Over time as your vehicle ages small cracks may form in your AC system parts such as the compressor, condenser, evaporator, receiver-dryer, expansion tube and connecting hoses allowing freon to escape. If this occurs, you need to replace the failing part and have your freon recharged.

Q: How long should a Freon recharge last?

A: If your car's AC system was recently repaired and required a freon recharge it should not need to be replaced again. Your AC system is a closed or sealed system that does not allow freon to escape. Freon is not like gasoline; it does not get depleted. If freon is escaping after your car's AC system has been repaired, then additional work may need to be done to find the leak.
