How Air Conditioning Units Are Repaired
Air workout isn't a luxury when you're driving in a car in 90-caste rut. When a person overheats they can lose focus, have a shorter atmosphere and make mistakes. Luckily, it'due south possible to fix a broken Ac unit. There are 3 main parts to the air workout unit – the compressor, the condenser, and the evaporator. The error could lie with any of those parts or it could be that the unit of measurement needs recharging. First, brand a visual inspection of the unit to meet if in that location are any obvious signs of impairment.
Symptoms
The obvious symptom that something's wrong with the air-conditioning unit is that it doesn't run cold plenty merely in that location are other less obvious signs that suggest a problem with the unit of measurement including loud noises when the compressor is running or the Air conditioning clutch not moving. The fault could be something equally simple as a blown fuse, an opening in the wire to the clutch coil, a faulty clutch coil, a low-pressure lockout or something more complicated to correct.
If y'all're going to get this checked out by specialist mechanics, tell them the symptoms you've noticed which will give them a inkling to the trouble simply they'll ordinarily carry out a visual inspection of the air conditioner's compressor drive belt, it'southward serpentine belt and any other attainable components for damage, cracks and leaks. Replacing ane of these parts is the quickest and cheapest manner of repairing the mistake but if the issue's not obvious, the engineers volition demand to bank check how well the air-conditioning compressor is operating.
Air Conditioning Compressor
If no leaks are found during the engineer's visual inspection, dry nitrogen will exist used equally a pressure examination to brand certain there are definitely no leaks in the system. A vacuum pump is then used to remove any wet and static air from the system.

Put it at its highest setting and use the fastest fan speed as this volition piece of work the system to its maximum which volition accuse the system fully. Once the engine's running and the system is switched, the refrigerant enters the system and y'all'll begin to see the pressure gauges increase from low to loftier pressure. Your engineer will accept to be careful not to overfill the refrigerant as this tin lock upward the compressor, although in some cars the compressor shuts off automatically when the organisation's overcharged.
Regular Maintenance
Spotting small-scale problems before they become big headaches for you is the key with your ac but you tin can prevent problems by running the system once a week for at least ten minutes to maintain gas pressure and to proceed the compressor running properly. Run the defrost mode for at least five minutes too. This means that you'll need to use the air conditioning in all weathers and all seasons, including wintertime. Making sure that the arrangement is recharged when it needs to be and getting it regularly serviced are the other ways y'all'll keep information technology working.
