Air conditioning repairs can be expensive. Technicians might charge hundreds of dollars to troubleshoot and service an A/C system. Before spending money on professional services, try to flush your vehicle’s A/C system yourself. The procedure for flushing the A/C system is fairly straightforward. You need a few automotive tools and about two hours.
Park your vehicle in a safe location on even ground. Engage the parking brake, but allow the engine to idle. Turn on the air conditioning system. Open the hood.
Locate the air conditioning service fittings. The low-side fitting is located on the refrigerant hose that goes from the accumulator to the compressor. The high-side fitting is located on the refrigerant hose that goes from the compressor to the condenser. Remove the plastic caps on the service fittings.
