Need Help with HVAC Recharge ?
How do you know if you need an AC recharge?
In the simplest form, you'll know when you need an AC recharge if your AC starts pumping warm air instead of cold. There is a very limited amount of refrigerant in the system, and when even small amount leaks, the system can no longer function properly, delivering lukewarm air instead of cold air.
The reason your car's A/C system needs to be recharged is that, over time, the refrigerant gas that makes the system work will leak out of the system. This process can take many years -- but, eventually, every vehicle will need its A/C system recharged.
Why Does Your Air Conditioning
On hot, sunny days, few things are more frustrating than having to ride around in a car with a nonfunctional cooling system. If your car’s air-conditioning system blows only warm air on hot days, it’s probably because it is low on refrigerant, and the most likely cause is a leak somewhere in the system.
