Cool Zone, Inc. is a company one can trust to have their mechanical work completed. The work was scheduled and performed exactly as stated without any delays or complications. The installers maintained my residence very neat and clean during the entire time of the new A/C installation. After the installation was completed they guided me through the thermostat settings and initial setup. They also assisted me with acquiring the Lennox App for my smart phone and instructed me on how to use this app. Cool Zone is a company I can truly recommend to anyone needing mechanical work.
