Absolutely perfect!! Courteous, professional, clean, timely service!! Technicians (Vano and Aleksey) were on time, explained every step of the process, and even took off the shoes in the house to help us avoid to washing floors later :) The job they performed was meticulous, with them paying attention to the tiniest details. Also, I want to express my gratitude to the highly professional customer service of Green Air Care - all communications were courteous, on time as well as kept us informed all of steps of the process.Highly Recommend!!!!
