Found Dial One after searching my community FB page for duct cleaner recommendations. Got a prompt booking and then when I had an unexpected renovation-related delay (oh, aren’t they all, lol), Joe re-booked the appt., graciously and courteously. On the day, Aiman did the job and he was professional both in his work and demeanour: showed on time, was thorough and thoughtful as he moved through the house, explaining as he went. No upsell, just the service as promised, well done, at the price I was quoted. Def. recommend, thanks, Aiman and Joe!
