A car air conditioner is a modern car climate system that is responsible for both air cooling and heating and ventilation of the car interior. When it rains, the air conditioner is useful as a dehumidifier for foggy car windows.
This system has a bunch of pipes, connecting rings, an air conditioning radiator and a compressor to which oil is added.
The easiest way to evaluate the efficiency of a car air conditioner is to measure the air temperature in the cabin using a conventional thermometer with the engine running and the climate system cooling mode turned on at maximum. The temperature of the air supplied to the cabin from the ventilation system should be approximately 41℉
A professional inspection of the air conditioning system is carried out in several stages
- visual check of the air conditioning system for metal corrosion, holes, cracks or other mechanical damage.
- Using special equipment (gas analyzer), a leak test is carried out. Using special equipment or an ultraviolet lamp, it detects freon, the vapors of which are released in places where the seal is broken, including from microcracks invisible to the human eye.
- Determine the level of refrigerant pressure in the air conditioning system and, if it is insufficient, refill the refrigerant.
- Preventative cleaning of the air conditioner radiator is carried out, with preliminary partial disassembly of the front part of the machine and washing with special liquids and solvents.
- Check the oil level in the compressor tank and top it up if necessary. If the machine has been in use for 5–7 years, a complete oil change is recommended.
- If an unpleasant odor appears in the cabin, antibacterial cleaning of the ventilation and air conditioning systems will be required. The reason for this is that over time, bacteria accumulate on the air conditioning evaporator in the car.
You also need to pay attention to your car's air conditioning because of health safety reasons. The less often the system is cleaned, the more bacteria and contaminants accumulate in it. In addition to the fact that the air becomes musty, the likelihood of respiratory tract diseases increases.
We recommend turning on your car's air conditioning for a few minutes once a month, as the system contains oil designed to lubricate the air conditioning parts. When turned on, it is redistributed throughout the system, providing a lubricating effect.
This will help keep the system in working order and increase its service life.
