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.

EPIC Protect Plans

We're here for you if something goes wrong.

Our service plans can eliminate unexpected, out of pocket expenses for repairs with affordable coverage you can trust beyond the original warranty. It's peace of mind protection you can count on!

The protection you expect, the service you deserve.

When a problem arises and service is required, you need it fixed as fast as possible. But then you're faced with a costly repair bill. Are you and your budget prepared? Especially when you have no way of knowing when or how often service may be needed.

EXTREMELY LOUD AND ANNOYING WORST PURCHASE EVER

dajg 8/25/2024

If I could give it 0 stars I would. Very very disappointed. We bought it in November but did not have help to install it until after the three month return window. While it cools and heats pretty well IT IS SO NOISY IT MAKES ME WANT TO SCREAM

Great product

Hans55ley 11/30/2023

This is the 3rd purchase and I have been satisfied with this product. I dont have central air and heat. It provides enough heat in the winter and cool in the summer and keeps my home comfortable.
