How Air-conditioning Units Are Repaired
Air workout isn't a luxury when you're driving in a car in 90-degree heat. When a person overheats they can lose focus, take a shorter temper and make mistakes. Luckily, it'southward possible to set a broken AC unit. At that place are three main parts to the air conditioning unit of measurement – the compressor, the condenser, and the evaporator. The fault could lie with any of those parts or it could be that the unit needs recharging. First, make a visual inspection of the unit to see if there 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 enough but at that place are other less obvious signs that propose a trouble with the unit including loud noises when the compressor is running or the AC clutch not moving. The fault could be something as unproblematic as a blown fuse, an opening in the wire to the clutch roll, a faulty clutch coil, a depression-pressure lockout or something more complicated to correct.
Visual Inspection
If you're going to get this checked out by specialist mechanics, tell them the symptoms you've noticed which will give them a clue to the problem but they'll normally carry out a visual inspection of the air conditioner'south compressor drive belt, it's serpentine chugalug and whatever other accessible components for damage, cracks and leaks. Replacing 1 of these parts is the quickest and cheapest way of repairing the fault just if the issue'south not obvious, the engineers volition need to check how well the air workout compressor is operating.
Air-conditioning Compressor
If no leaks are constitute during the engineer's visual inspection, dry nitrogen volition be used as a pressure test to make sure there are definitely no leaks in the arrangement. A vacuum pump is then used to remove any moisture and static air from the organization. Once that's done, a refrigerant source is attached, which can be bought from your normal automobile parts retailer or the internet. Make sure the engineer'southward using the refrigerant appropriate for your motorcar as set up out in the vehicle'south handbook or listed on the manufacturer'south website.
While It's Charging
While the system'southward being recharged, start the engine and turn the air conditioning on. Put it at its highest setting and utilise the fastest fan speed as this will piece of work the system to its maximum which will accuse the system fully. Once the engine's running and the system is switched, the refrigerant enters the system and you'll brainstorm to see the pressure gauges increase from low to high pressure. Your engineer will have to be careful not to overfill the refrigerant as this can lock upwardly the compressor, although in some cars the compressor shuts off automatically when the system'due south overcharged.
Regular Maintenance
Spotting small issues earlier they get big headaches for you is the fundamental with your ac simply y'all tin prevent bug by running the system once a week for at least ten minutes to maintain gas pressure and to keep the compressor running properly. Run the defrost mode for at least five minutes too. This ways that you'll need to use the air-conditioning in all weathers and all seasons, including winter. Making sure that the system is recharged when it needs to be and getting it regularly serviced are the other ways yous'll keep it working.
