Called David on a (glowing) recommendation from a family member. Contacted David who got back to me right away, and set a date which I subsequently had to cancel, however David was very understanding and we booked another time. VERY HAPPY that David was recommended to us, himself and his assistant were on time, clean, courteous, and very thorough (so thorough he was finding stuff that should have been cleaned last time the ducts were cleaned, and 'treasures' my kids had left in the vents). Not only did he do a great Job, but also made some recommendations on how to improve our airflow to the upstairs of our home
Highly recommend David, and will be calling him back in a few years
