Has your AC suddenly stopped cooling as it used to? Are you worried that a refrigerant leak could mean replacing the entire coil? Before you panic, there may be another option. In some situations, modern AC leak sealant liquids can help fix small leaks and keep your system running without an expensive coil replacement.
Let’s see how they work and when they are the right choice.
What Is AC Leak Sealant?
AC leak sealant is a special liquid added to the refrigerant system. It is designed to seal tiny leaks from the inside. When the sealant reaches a small leak, it reacts with air and forms a strong seal that helps prevent more refrigerant from escaping.
This solution is only meant for very small leaks. It cannot repair large cracks or badly damaged coils.
When Can Leak Sealants Help?
Leak sealants work best when the leak is minor and the rest of the air conditioning system is still in good condition. Instead of replacing an expensive evaporator or condenser coil right away, a technician may recommend using a sealant to extend the life of your system.
This can save homeowners both time and money while delaying a larger repair.
When Is A Coil Replacement Better?
Not every leak can be repaired with a sealant. If the coil has severe corrosion, multiple leaks, or significant damage, replacement is usually the safer option. A professional inspection can determine which solution is best for your home.
Trying to ignore a refrigerant leak can make your AC work harder, increase energy bills, and eventually lead to bigger repairs.
Why Professional Service Matters
Adding leak sealant is not a DIY job. HVAC professionals use specialized equipment to locate the leak, check refrigerant levels, and confirm whether the sealant is appropriate. This ensures your system continues operating safely and efficiently.
For homeowners across Reno and Sparks, changing weather and heavy summer AC use can put extra stress on cooling systems. Having a trusted local HVAC company inspect your system helps catch small problems before they become costly ones.
