Summer is here, and we can feel the heat here in Central Florida! If your vehicle’s air conditioning isn’t holding up to the temperatures, you may need to have yourA/C Inspected.
We’ve heard several people talking about those DIY manual recharge kits that let you add refrigerant into your system. Many of these kits seem like an easy, “too good to be true” alternative to a full AC Service, and that’s because it is too good to be true!
Manual Recharge Basics
Manual recharge systems do not evacuate the freon in your system. Instead they add refrigerant on top of your current levels. It’s like adding fresh, new oil on top of old oil – topping off fluids does not solve any problems, it only temporarily covers up the symptoms. In fact, topping off can even lead to bigger problems and costly repairs!
Refrigerant does not evaporate, it leaks. If your air conditioning is low on refrigerant, it is leaking refrigerant into the atmosphere. While the environmental impacts of leaking refrigerant are significant, DIY kits pose many more risks to your vehicle.
Contaminants in your system
Not only can refrigerant continue to leak into the atmosphere, but contaminants can leak into your system. Dirt, dust, and grime can build up inside your A/C, plugging up the hoses and pumps necessary to keep your car cool. Even water can wreak havoc in your A/C system.
Manual recharge kits often leave behind water in the lines. When water and refrigerant mix, they will hydrolyze, forming hydrochloric or hydrofluoric acids that can deteriorate parts, corrode metal, and fill the system with sludge. This can cause problems much more costly than the few dollars you save purchasing the DIY recharge kit.
Because there are many types of refrigerant, you may not know if the refrigerant you are adding is the same as the refrigerant currently in your system. Mixing refrigerants can cause dangerous chemical interactions. In addition, mixing refrigerants can cause damage to the compressor or other parts of your A/C system. If you cannot identify the type of refrigerant in your system, you should have a professional evacuate the system and replace with new refrigerant rather than risking “topping off” with the wrong type.
Many recharge kits also feature a stop-leak sealer, claiming to fix and prevent leaks. One of two things typically happen with these sealers, either it won’t work at all and you will continue to leak refrigerant into the atmosphere, or it will stop the leak, and it will block your hoses, the compressor, and the pumps in your A/C! Kits that offer a “stop-leak sealer” may temporarily plug leaks, but can interfere with system components and lead to larger, costly repairs. This “stop leak” doesn’t know where the leak is, so it blocks everything in its path.
If there is a problem in the A/C system, DIY kits will only cover up the symptoms temporarily. Water and contaminants can get into the system, refrigerant can leak out into the environment, and leaks are not repaired. All of these factors can lead to even more problems, and more expensive repairs, for your vehicle.
