Have you ever wondered what’s causing your air conditioner to produce cool air? You are right, that’s the magic of the refrigerants! Another question: how much refrigerant does your unit need to cool your home? It can be really tricky. Since most of the homeowners are not very knowledgeable about this matter, we have some pieces of information to guide you in getting the answer to your concern.
The General Rule of Thumb
When estimating the amount of refrigerant in a residential A/C unit, the general rule that is used is in the 2-4 pounds per ton of cooling. Say, for instance, recharging a 3-ton A/C with a 35-foot line set from empty level will need an approximately 6-12 pounds of refrigerants. However, this general rule of thumb may depend on different variables. Take a look at these factors that determine the amount of refrigerant inside your cooling system:
- A/C Size. The size of your air conditioning unit significantly affects the amount of refrigerant needed to produce cool air. Of course, the bigger unit needs a larger liquid line on the line set, thus requires greater capacity.
- Length and Size of Copper Line Set. The greater the distance between the evaporator and condenser coils, the more refrigerant is needed. Air conditioning units come from the factory with the right amount of refrigerant which complies with the distance between these two crucial parts.
- Size of Evaporator Coil. Many homeowners would prefer larger evaporator coils for greater cooling power and efficiency. This however also means, your unit needs a greater amount of refrigerant inside.
- Type of System. Split systems may need a greater amount of refrigerant as compared to packaged units. Since there are indoor and outdoor components for this type of A/C, there are lots of factors that should be accommodated like the line set and coils. All of these can be determined by a professional installer.
