Why NSI Protection Plus?

Our service plan is an economical way to extend the terms of your product's manufacturer parts & labor warranty.

Most manufacturer's limited warranties leave customers with no protection against the rising cost of repairs.

Even the best products can malfunction and the most minor repairs can cost hundreds.

About NSI Protection Plus

Administered by Warrantech and insured by AmTrust Financial, NSI Protection Plus is the largest service network in the industry with 30 years of building the network and over 22 million in paid claims.

The most comprehensive repair plans in the business!

  • Day one coverage on special features
  • Removal and reinstallation coverage
  • $25 Laundry credit (Washers and Dryers)
  • 5 year appliance contracts include 10 year major component coverage
  • $250 Food credit (per incident, eligible products)
  • The only true "No Lemon Guarantee" in the business
  • No "CAP" on repairs or replacement, unlimited repairs.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Its not the right kind

Louise 14 12/19/2023

Maybe I would be satisfied if I had been sold the right air conditioning. I was sol air conditioning for the window instead to be installed in the wall. On march it doesnt work they change something and April 5 th they change the air conditioning but they installed always a window instead the only one for the wall. I want you change for the good.

New A/C

Lake loafer 8/28/2023

I installed a/c a month ago in a second floor bedroom. Did not use until temperature was in the high 90s-100s last week. The a/c worked great and cooled the room quickly. The a/c was not too loud and I used the energy saver mode. Our last window a/c lasted 20 years doubt this one lasts that long. Case did come with a dent in it.

Great size

Sleepy D 8/20/2023

I bought this window a/c month ago and prior to installing I noticed a dent in the unit case. So check it out for dents as soon as u receive the product. Have not used it yet to evaluate how well it cools but with hot temps on. Horizon I think I will know if it is any good. Looks about like the 22 year old a/c it is replacing. Dont think it will last as long as the old one.

LG -18000 btu Air Conditioner

Mike Fox 8/9/2023

I replaced my LG Air Conditioner after 20 years with another LG 18000 btu Air Conditioner because it worked really well for that period of time. I chose LG for my replacement because it was very reliable.

LG air conditioner

AC unit was delivered and we installed it. We noticed immediately when it was first turned on that it is very loud and vibrates a lot when the compressor comes on.

JackieBaucon 5/17/2023

The air conditioner I had played out in September of 22 and I needed another one. So I found the exact same brand and almost just like the one that quit and I bought a new one its really good. The one I had lasted for about 15 years it served its purpose..
