Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

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.

AC and Heat--great combo!

AW26 6/10/2024

I have the smaller of this unit, too, and love it for a small bedroom over my garage. I'm using this larger unit for the other, bigger room over the garage and couldn't be happier with the outcome. (Those rooms are not well insulated.) The supplemental heat is perfect for cold mornings. And the AC itself is excellent, keeping the room cool from all the heat that rises in the late afternoon. I'm especially fond of the 'eco' mode, as it keeps the room cool without it becoming too cold. The unit (while heavy) was easy to install and I was cooling the room within minutes. It used to be tough to hang out in the rooms above the garage in the peak of heat in summer and cold in winter but now we can use them all year comfortably!

Will not disappoint

EHairs 4/9/2024

This unit is amazing. I was super excited about this unit and it did not disappoint. This unit was easy to install and I was able to do it without my husband. Supplemental heat feature was a plus as it came in handy these last few days as the weather has cooled down. Having the remote will make it easy to control and switch over without having to always walk over to the unit. I would definitely recommend.

Easy to Install & Use

This unit has worked very well to heat and cool my husband™€™s home office. It is much quieter than the last one and he loves that it has heat as well as AC. It was very easy to install and program.

The perfect AC unit

TAH0220 4/8/2024

We received this unit and it has been added value to our lives since we opened the box. We were up and running quickly as the unit was super easy to install. The unit cooled down the area quickly and was very quiet. Being able to have the additional heat feature came in handy these past couple of days when we had a cold front. We also loved the fact that the unit helps to reduce dust in the air which is a huge benefit. You definitely can™€™t go wrong with this unit.
