Understanding AC Leak Sealers
An AC leak sealer is a chemical solution designed to seal small leaks within an air conditioning system. These sealers circulate with the refrigerant and react with moisture at the leak point to form a seal. They’re often used as a temporary fix to avoid costly repairs or replacements.
How Do AC Leak Sealers Work?
AC leak sealers function by:
- Circulating through the AC system with the refrigerant.
- Reacting with moisture at the leak site to form a seal.
- Sealing small leaks in components like hoses, gaskets, and metal parts.
It’s important to note that these sealers are most effective for minor leaks and may not work on larger or more severe leaks.
Pros and Cons of Using AC Leak Sealers
Pros:
- Cost-effective compared to major repairs.
- Easy to apply with minimal tools.
- Can extend the life of older systems.
