" Brandon and Nate did a fantastic job! They were nothing but polite, and helped explain the work they completed. We are really enjoying our newly installed Ecobee4, which gave us control back of our house! We are also appreciating the whole-house humidifier which has improved our quality of sleep. Thanks to Liz for keeping us updated on scheduling, and making changes to get us scheduled asap! A big THANK YOU to the Harmonic team for the fantastic work!"
