Installers should arrive on time and bring all the necessary equipment required to complete the job on the first trip.

Installers should be professional, efficient and considerate of your home, cleaning up after themselves thoroughly.

Installers should use ozone friendly refrigerant and insulated copper linesets to connect the outdoor and indoor units.

All external linesets should be covered with UV protected linehide covers.

The outdoor unit should be elevated, leveled and secured properly.Installers should demonstrate how to operate and maintain the new system and review the inspection process.

Installation company should provide the necessary mechanical and electrical permits and ensure your system complies with all local building codes.

After Install
