Technicians Eric and Brandon came out on time (they were even slightly early). Very professional and friendly. Both technicians provided information throughout the job regarding all the steps to cleaning the ducts, and also provided tips along the way regarding maximizing home efficiency of furnace. Technicians were very clean, ensuring carpets were protected, taking shoes off, etc. One of the best experiences I have had to date with any home service. Would highly recommend. Price quoted was price I paid.
