We have had people burn a large portion of a living room rug, smash televisions, allow a pet to chew up a dresser in our pet free home, and puncture holes on the inside of the refrigerator.

We buy many refrigerators new from Lowes and get free delivery.

In the span of 6 months, I had to replace the AC unit, water heater, and refrigerator.   

Duct is maybe not the right word exactly because they just cover the refrigerant line.

Appliances included are a refrigerator, stove, dishwasher and microwave.

If they say that they were told the refrigerator worked and it didn't they would have to prove it and state an amount they were damaged.

The prices on Freon are rising and will continue to rise in coming years as it's only available from existing stock and aftermarket sales of refrigerant recovered from decommissioned systems.

I have gotten several deals over the years from people calling me from my business card refrigerator magnet that I sent years earlier and now the owner or relatives are calling me.Jon has a really good point and is correct you do have to send tons of letters and the key is to be consistent.
