Many changes have been made to freon recently and new government regulations have spurred refrigerant manufacturers to come up with “alternative” refrigerants that are claimed to be more cost effective. These are called “drop-ins” and are considered replacements for R22 freon. DO NOT USE THESE DROP-INS or allow your A/C company to use them. Many A/C manufacturers including Lennox have placed restrictions on their use and the results are voided warranties on your compressor. We encourage you to research on your own the pros and cons of using these refrigerants and as always, contact us with any questions.
As a note, A Team Hope Company and it’s subsidiaries NEVER uses replacement “drop-ins” nor do we advocate the use of them. Please make an informed decision before using these in your system.
