    Consider getting the condenser outside of the drip line from the roof of the home. Ice from the roof can damage condensers.

    What BaldLoonie said plus: Get the ten year warranty with labor and refrigerant included. (It costs more up front.) Keep any filter clean so that equipment lasts longer and costs less to operate.
