First of all, in a perfect world, your air conditioner should never need more refrigerant. Refrigerant isn’t used up like gas in a car.
So you only need more refrigerant if there is a leak somewhere. And to know that for sure, you need an AC technician to measure the amount of refrigerant in your air conditioner. (This is one reason a yearly maintenance visit is a good idea.)
Topics covered in this video:
• Low refrigerant levels are usually caused by a leak somewhere within the system or a component that handles the refrigerant.
• My energy bills are going up and it’s taking longer to cool my home.. sometimes it may run all day and never get to a comfortable temp.
• I’ve spotted ice on my coils and I’m hearing unusual noises.
