When the air conditioner in your 2016 Nissan Sentra starts blowing hot air, you likely have a freon leak. Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant. The A/C system in your Sentra consists of a compressor that is belt-driven, an evaporator and freon. If there is a problem with your compressor or evaporator, adding freon will not restore cooling. How to add freon to your 2016 Nissan Sentra: hook up the can of refrigerant (likely r-134a) to the low pressure port. When your compressor kicks on, add freon to the correct pressure. In addition to cooling, freon lubricates the compressor when it runs.
