Most people know that air conditioners run on refrigerant, a chemical combination that encompasses a number of specific names and formulas. The specific type and amount of gas depends on the make and model of your air conditioner, but all refrigerant has a few things in common: a relatively low vaporization point, an ease of shifting from liquid to gaseous form and back, and the ability to pull heat energy from the nearby air in the process. It’s what makes air conditioning possible, and has proven to be a revolutionary technology in hot cities like Mesa, AZ.
A lot of people assume that air conditioners consume refrigerant the way a car consumes gas, and that when a technician recharges refrigerant levels, he or she is just “refueling” the system. In fact, the opposite is true. The system relies upon precise amounts of refrigerant levels to do its job. Understanding why will help you understand why you can’t just recharge refrigerant levels when they get low.
A Closed System
Refrigerant moves through a closed system in your air conditioner. The system first applies a great deal of pressure to it while releasing the heat: shifting it to a liquid form. It then moves the liquid through an expansion valve, which releases a precise amount into the evaporator coils where it shifts back into a gas. The gas then moves to the front of the system to start the process over again. This all relies upon specific amounts to work. When the refrigerant levels are lowered, it results in an imperfect cooling system: lowering efficiency and increasing the strain on the rest of the system.
Seal Before Recharging
All of that means that, if there’s a leak, simply recharging the refrigerant won’t work. Otherwise, it will just leak out again and you’ll have the same problems a short time later. That’s why you need a trained professional to pinpoint and seal the leak before you can properly recharge the refrigerant.
