Air conditioning systems work by removing indoor humidity and heat, and replacing it with cold air. The primary element in your AC that makes this possible is the refrigerant. In the past, R-22 — popularly known as Freon — was the most common refrigerant. This is no longer the case, however. Numerous studies linked R-22 to ozone layer depletion and human health issues.
There are various safe refrigerants used nowadays for AC units. Learn more about them so that the next time you hire an AC service for Draper clients like those from Airtime Heating & Cooling for a tune-up, you know what to expect.
R-134A is a hydrofluorocarbon with no chlorine in its mix. In fact, R-134A only has one component. This refrigerant is efficient, provides excellent air quality and improves your unit’s reliability. The effect of R-134A on the ozone layer and human health is insignificant.
The thermodynamic properties of R-407C are similar to that of R-22, which is why it is one of the most common alternatives to the latter. It includes a blend of various coolants which are 100% safe for the environment and human health. R-407C is the commonly used coolant in ductless split systems and packaged ACs.
This coolant is a blend of pentafluoroethane and difluoromethane. These constituents are both non-ozone depleting. R-410A is renowned for its energy efficiency. The coolant can also handle high pressures and cooling capacities better than others. R-410A can however not be used in units designed for R-22 since it requires a different pressure gauge.
The type of coolant used in your AC might not seem important to you. Without it, however, there will be no cooling in your AC. You should also know that there are various environmental regulations on the type of coolant to use in your AC.
With expert routine maintenance, you will be sure that the refrigerant you are using is safe and complies with any set regulations.
