Any recommendations for a small pin hole leak a/c
I have a Rheem 5 ton residential a/c condenser unit that sits outside the house.
This unit and all the similar ones in this neighborhood are approximately 20 years old.
This type of a/c condenser uses standard R-22 type freon.
This needs to be recharged after 25 - 28 months with R-22 freon.
Has anyone used these two types of products, Do they work, and what are the disadvantages.
1. A/C Leak Freeze® will stop leaks of refrigerant gas in HVACR air conditioning and refrigeration systems in homes and commercial buildings. A/C Leak Freeze® is inert until it mixes with the refrigerant. A/C Leak Freeze® is activated by refregerant escaping at the site of a leak — forming a chemical weld and sealing the leak.
2. A/C EasySeal: #4050-06
