Some people believe air conditioners create cool air. It’s a reasonable assumption; when you put your hand near the vents, you feel cool air enter your home. However, this assumption is not entirely accurate. Instead, refrigerant, a chemical blend that changes easily from liquid to gas, removes heat from your home so that cool air can return through the ducts.
Refrigerant is a generic name for one of a number of chemical blends that continuously evaporates and condenses as it moves throughout your system. Originally, refrigerant was far more toxic than it is today, and it was once a major source of ozone depletion. However, these blends have been phased out in favor of refrigerant that is less toxic and better for the environment.
The ideal refrigerant blend uses very little energy to change from gas to liquid form. It begins its cycle at the compressor, where the chemical is compressed into a very hot, high-pressure gas so that it can move through the rest of the system. Then, it moves to the condenser coil. Here, a fan blows the outdoor air over the coil. As the air passes over the coil, condensation occurs and heat releases from the refrigerant into the air.
The cooled refrigerant, now a high-pressure liquid, moves indoors toward the evaporator coil after passing through an expansion valve which lowers both the temperature and pressure of the liquid. A fan blows warm indoor air over the evaporator coil starting the process of evaporation; refrigerant changes into a gas, absorbing the heat from your home in the process. Then, refrigerant moves outdoors to the compressor to begin its cycle again.
When your system is installed, refrigerant is given a certain “charge,” or level, at which it is to remain. If you run low on refrigerant, then either refrigerant was not charged correctly in the first place or you have a leak somewhere along the refrigerant line that needs repairs.
If you have a problem with your refrigerant, our technicians can recharge the refrigerant and seal any leaks for continued performance and efficiency.
