Hello, I am sorry you are having issues with the AC. I'm doubtful about your furnace claim, because If the furnace was oversized, the furnace would not have worked for the last 3 heating seasons at all.
If your AC has a Freon leak, which can happen no matter what brand you pick, or what company you select, the manufacturers don't cover that. We have been clear with you.
You also declined the extended labour warranty. If you had not, the manufacturer and us combined, would have covered all of this under warranty. All brands including Lennox, Carrier, Trane, etc only offer 1 year coverage on Freon.
This is an issue with central air in general as the new Freon gas is synthetic and runs at a higher pressure and can cause it to leak out over the cold winter.
We are still here to help you, please don't let a manufacturers defect tarnish our hard work and support of you.
I don't think the car someone drives has anything to do with anything sir, my brother Christopher is noted here on HomeStars over 300 times for his honest, helpful knowledge. Just because your AC has a defect, isn't on him or his footwear.
I am here personally, if you need more help - and willing to by pass the diagnostic fees for you.
