We needed climate control for our attached garage where I spend a lot of time working.  But summer especially in South Texas made it impossible to be in our garage for more then a few minutes!  After researching our options, I decided on the 8,000 BTU Frigidaire AC/Heating model.  This unit was easy to install and made an instant positive difference.  In fact, we were so impressed, we bought a second unit for the same garage to put in the other window.  Now the sun can bake and the freezing winds can blow but our garage stays at just the right temperature all year round.  And they are pretty energy efficient as well. Choosing these units was an excellent decision to go with an excellent product!
