Nice unit but exterior side could be built better

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, thatÕs 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. IÕm giving this unit three stars. It could easily be four or five if it was built better.

Easy installation by homeowner.

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.

I am very happy with both the installation and the performance of the unit. Here in south Florida where itÕs 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

Great performance

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