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.

Nice unit but exterior side could be built better

Desert Punk 7/7/2021

This review is for model number LT1237HNR with optional grille AXRGALA01 and the optional sleeve. Installation was quick. Good thing because the new unit and sleeve were not as high as the old one so the contractor had to fill in the gap with insulating foam then trim around the opening on the interior and exterior. This was expected. Here is where I advise a little caution. The back outside facing of the unit is of flimsy construction. First there is an included plastic diamond mesh that offers MINIMAL protection. If this unit is installed in a high traffic area or can be reached by people walking by the back of the unit will be exposed. If you have a lot of birds and insects around your home the back of the unit will be exposed. Also if you value how the unit looks from the exterior this may not be the unit for you. This is why I bought the optional grille. The grille itself is flimsy with the louvers easily crushed as it is stamped from light gauge metal. But the worst part is the instructions say you have to remove the unit from the sleeve before Installing it. In my case thats going to be difficult what with the trim and caulking around the unit. Plus the louver arrived after my unit was installed. Wish I knew beforehand so I could have postponed installation I am going to try attaching from the outside as the screw holes line up but it will look a little wonky. I just want to keep the birds and wasps out. I would have loved to have the option have a more durable louver or better designed exterior face of the unit. I understand that engineering and economic principles are in play but still I would have paid more if given the option. Im giving this unit three stars. It could easily be four or five if it was built better.

The product works great and the installation instructions made it very easy for the homeowner to install. I also bought the new sleeve as part of the system.

JP56 4/19/2021

I am very happy with both the installation and the performance of the unit. Here in south Florida where its been hot and sticky the unit has no problem in keeping our bedroom nice and cool. I will definitely buy another unit or recommend it to a friend

DaBearDen 3/23/2021

I installed this in my 315 sq ft tiny house. It has done great in heating it even with temperatures in the 20s. I am sure it will do great in summer months.

Very Expensive to Run Heater Loud

Professor Gerry 1/21/2021

We installed this unit in our eat-in kitchen in December 2020 to provide supplemental heat in the winter and additional cooling in the summer. The unit is very loud. It is also incredible expensive to run. Even though we only run it a few hours a day set at 64 degrees it has doubled out monthly electric bill The thermostat is so inaccurate as to be useless. I hope the unit does better in the summer.

Excellent heating cooling

Rr4455 1/10/2021

This is my second unit of its kind and we have loved the effective way it has cooled heating a home extension. The only issues we had is the noise from the blower. It would have been great if a direct wired option would be available.

Good Heat Noisy Highly Inaccurate Thermostat

Professor Gerry 12/22/2020

I bought this unit about a month ago to heat an eat-in kitchen and cool it in the summer. It heats well. However it is loud. The thermostat is widely inaccurate. The instructions are very poor. I wont know how well the air conditioner works until the summer.
