NO WARRANTY EVEN IF YOU PAY EXTRA FOR IT.
Beware
I purchased a casement window air conditioner AND the asurion 3 year warranty extension for the unit. The air conditioner was faulty from day one in that the temperature control did NOT control temperature and the compressor would not stay on unless the unit was set at the minimum 62 F setting. I called the manufacturer/distributor of the air conditioner and they informed me that there was NO WARRANTY on the unit because it was sold by a third party. The unit was only warranted if it was purchased directly from the distributor themselves.
I then checked with the extended warranty company *asurion" and was told they would not warrantly the product until after 12 months subsequent from purchase.
I highly suggest that anyone concerned with receiving a working product from Amazon should take care to investigate thoroughly before placing an order.
I contacted Amazon and they will replace or refund these items however I see no choice but to get a refund. Replacement with a non-warrantied product seems like something even a very foolish person would not consider.
Asurion's policy on not honoring it's extended warranty until 12 months after purchase is also hmmmmm unusual and makes their warranty products a questionable purchase.

Prompt service
Excellent service and got my refund via e-gift card. My portable ac heat combo unit failed after almost 3 years of use and I was refunded my purchase price. It’s easier to claim using their chat support.

Amazing, effortless, easy!
Excellent experience! I made a claim and they immediately issued an Amazon gift card for reimbursement. Entire process from start to finish was probably 2 minutes or less. Amazing, effortless, easy! Will purchase again for any other items that qualify.

ASURION 4-Year Housewares Plan - An Excellent ROI
The ASURION 4 Year housewares protection plan was definitely one of the best investments that I've made to date. I had a large, 12,000 BTU portable air conditioner that stopped working properly in its third year of use--one year after the manufacturer's warranty had expired--essentially leaving me with a glorified hot air fan. I proceeded to file a claim on my ASURION 4 Year housewares protection plan. The process could not have been easier and did not require much documentation since the plan was already linked to my prior purchase of the AC off Amazon.
I received an Amazon gift card within minutes of filing the claim, thereby definitively demonstrating ASURION's broad coverage scope, reliability, and overall value.
As such, I used part of the gift card to purchase another four-year plan on a replacement AC unit that's now sitting in my office. Hopefully, I will not need to use it, but it's good to know that I have coverage if needed.
