The installer, William Karl, was excellent. Very friendly, patient and thoroughly explained everything step-by-step. He did a very professional looking installation with minimal disruption of the lawn and outside area (he deserves 5 stars). Our salesman, Danny, seemed very genuine during his presentation, however, after agreeing to purchase a system and signing a contract, he was less than professional. He promised an install date that we later found out was not possible, he could not schedule the installation, only the office could schedule installation (installation was actually not available until a week after his promised date). During the scheduling process, I attempted several times to contact him requesting written confirmation of the date to no avail. I finally contacted the office and was able to confirm a date and time on my own. I have not heard from Danny since the contract was finalized (obviously he was only interested in closing a sale and would say/promise anything to close the sale. I rate him 2 stars at best). Also, he stated that a cover for the unit was included in the sale; we later found out that was not true and we had to purchase an aftermarket cover.
