The main signs of a lack of freon

Freon is a refrigerant that circulates in the air conditioning system and provides cooling to the air. Over time, its amount can decrease due to natural leaks. Here are some clear signs that there is not enough Freon:

Decreased cooling efficiency: if the air conditioner starts blowing warm air or cools the interior very slowly, this is the first and most common sign of a lack of freon.
Unpleasant odor: the appearance of a musty or damp odor from the air ducts may indicate a malfunction of the evaporator due to a lack of refrigerant.
Oily traces: the detection of oily stains on the tubes and connections of the air conditioning system indicates a freon leak.
Frost on the indoor unit: Frost formation on the evaporator is also a sign of a lack of freon.
Hissing sounds: the appearance of extraneous hissing sounds during air conditioning operation may indicate a low level of freon in the system.

How often should the air conditioner be refilled?

It is recommended to check the freon level and, if necessary, refill the air conditioner every 2-3 years. However, if you notice at least one of the above signs, do not postpone a visit to the service center. Timely refilling will help avoid more serious breakdowns and extend the service life of the air conditioning system.

Monitor the condition of your car and contact specialists in a timely manner. Timely diagnostics and air conditioning refilling will ensure comfort in the cabin of your car in any weather.
