How To Recharge Room Air Conditioner

When you notice your room air conditioner is blowing out warm air or not cooling the room as desired, the air conditioner unit needs to be recharged with coolant, or refrigerant.

Purchasing a new air conditioner will also fix this problem, but can be rather costly.

To repair and recharge your current unit you can chose to do so yourself by purchasing a refrigerant recharge kit at a local hardware store.
